First things first: I'm a newcomer to the whole Linux idea and know basically nothing about it. I managed to install Ubuntu 24.04.3 LTS on a 2014 Macbook Pro. I chose it partly out of curiosity, partly to try and get away from some of the commercialized version (even though I'm not sure if, at least for the moment, I can rid myself completely of paid services). I had my first experience with the terminal but I know very little to be effective with it. However, I would like to learn to use it properly, or at least good enough to find my way around it.

My first question to the long-established among this community who are also willing to put up with a Ubuntu-illiterate like myself, pertains to a well-established mainstream service namely: "Good-Ol" Microsoft Office. I use it A LOT and, at least for the foreseeable future, can't see myself switching seamlessly to LibreOffice.

Using the Online version of Microsoft Office may be an option, but my templates are not accurately formatted there either.

I have read multiple posts with conflicting ideas. Some say I can install Microsoft Office 365 on Ubuntu, others are adement I can not. I also don't know how recent this information is. (Some supposed "links" to help with that, are broken).

I also managed to install Wine. I opened the *.exe file with Wine and i get the screen with the Microsoft logo and a line stating that "loading is in progress" - however, nothing comes out of it...

Anyone with helpful insights out there? - Can I or can I not Install Office365 on my Ubuntu Platform? The last post I found regarding this topic on this platform dates back to 2021. Anything changed since then?

I am not afraid of the "work" associated with this... I just need guidance, and possibly patience... ;-)

Since Ubuntu 25.04, I have issues the wifi connection. My motherboard has a Qualcomm FastConnect 7800 WCN785x card. Three cases (appears random to me)

1. No Wifi "5 GHz" when listing available networks, but the 2.4 GHz appears. In such case, iw reg get returns

phy#0 (self-managed)
country 00: DFS-UNSET

2. Wifi 5 GHz looks fine, but the bandwidth is slow, right now, for example, 144 Mb/s (5.2 GHz). In such case, iw reg get returns

phy#0 (self-managed)
country FR: DFS-ETSI

3. Wifi 5 GHz works fine with good bandwidth (about 800 Mb/s). In such case, iw reg get returns

phy#0 (self-managed)
country FR: DFS-ETSI

The 3rd case seems to appear only when it's not working in the beginning and I do iw reg set FR (I'm in France), although it affects only global and not phy#0. It also appears that if I start the computer in Power Mode: Power Saver (or Performance?), I am more likely to be in case #1 and if I start in Balanced, I am more likely to be in case #2.

For sure, case #1 didn't happened prior to Ubuntu 25.10 upgrade but it's not clear when bandwidth issues started, but it's been few months. I first thought I changed something at home, so I put the wifi access point closer to this computer, but it didn't change anything.

If I boot with the previous kernel, 6.14, instead of the 6.17, I always end up in case #2.

Right now, I'm in the 2nd case (with kernel 6.17 and started the computer in Power Mode: Balanced)

########## wireless info END ############

As reported in the topic On Ubuntu 24.04, Qualcomm FastConnect 7800, which supports Wi-Fi 7 and Bluetooth 5.3, has Bluetooth working, but Wi-Fi is not or here Install Qualcomm Wifi Driver this card was not working with the latest LTS Ubuntu 24.04, hence the update to minor versions. It was working fine with Ubuntu 24.10. I cannot pin point the time this issue started, as the first symptom was a slow bandwidth, I did not notice immediately.

There is at least an issue with regulatory (allowed frequencies), but it's difficult to investigate since wifi management changed recently and existing topic looks obsolete (no more iwconfig nor iwlist, crda seems outdated as well).

I'm trying to get sound out of my speakers on a Dell XPS 8930 where I've just installed Ubuntu 24.04.3 LTS with no success.

My audio device is:

I've looked on the web for advice on this and have found various help regarding pulseaudio.

I've reinstalled using : sudo apt reinstall pulseaudio

When I execute: systemctl --user restart pulseaudio.service

I receive:

Job for pulseaudio.service failed because the control process exited with error code.

See "systemctl --user status pulseaudio.service" and "journalctl --user -xeu pulseaudio.service" for details.

systemctl --user status pulseaudio.service yields:

     Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; enabled; preset: enabled)

When I try systemctl reset-failed pulseaudio.service

I see: 

Failed to reset failed state of unit pulseaudio.service: Unit pulseaudio.service not loaded.

So, even though I've re-installed pulseaudio and started it with pulseaudio --start (with not error message) the service isn't there.

So, what do I need to do next to fix this?

Thanks

I tried to connect the audio-playback interface from wpe-webkit-mir-kiosk to pipewire using the following

snap connect wpe-webkit-mir-kiosk:audio-playback pipewire:audio-playback error: cannot perform the following tasks:
- Connect wpe-webkit-mir-kiosk:audio-playback to pipewire:audio-playback (connection not allowed by slot rule of interface "audio-playback" for "pipewire" snap)

Isn't this how pipewire:audio-playback suppose to work? I tried chromium / firefox everything can imagine, all not working. I still trying to figure out how to play sound with wpe-webkit-mir-kiosk / chromium, and got totally stuck while my project is running out of time! Hope someone can help here.

How can find out what is missing?

I have been running 24.04 on Wayland for some days successfully. I logged off, selected the xorg graphics system and logged on again . unfortunately at this point the computer crashed and powering on defaults to booting with the xorg graphics system which also crashes. how do I default back to Wayland, as it was in the beginning?

I would like to install Zoom from snap so that it automatically updates every time there is a new release.

I tried to do it from the App Center. Zoom client shows up there, but when I click Install, it asks for authentication, then the original screen comes back, with the green button saying Install - Zoom is not installed.

When I try to install it from the terminal, I get the following error:

sudo snap install zoom-client

Fetch and check assertions for snap "zoom-client" (258) (cannot verify snap "zoom-client", no matching signatures found)

It offers me to update freedesktop and gnome apllication platform

I recently discovered an application called "software" in my system. All the applications I find there are offered to be installed from flathub. Considering that I recently installed Flatpak, I assume this is a Flatpak application. However, I would like to clarify whether this is actually a system application or not. In addition, I often receive notifications suggesting the update of the freedesktop and Gnome application platforms. Is it safe to update them?

Network problems so trying to remove and re-install Samba but get error 'apt-get check failed, you may have broken packages'. How do you clear broken packages? I've tried the suggestions in How do I fix apt-get check` failed, you may have broken packages but still get same error.

I think this should be easy but I am failing to do it and finding much contradictory information around the internet and much that goes back before various aspects of networking were changed. I last did this probably 20 years ago when I remember it being easy but so much has changed that I am going to ask here. Point me elsewhere if this is the wrong place.

I have two laptops: Tux and Juno (may convey their origins!), Tux is my main one and Juno is "fallback". Both are running Kubuntu 25.10 with everything updated daily. Both can use the various wifi networks I use as I move around. I use Tux as a qemu/virtual manager host running another Kubuntu 25.10 guest inside it. (So when things go pear shaped I can just use the backup copy of the guest and not have to reinstall and reconfigure everything.) That's a new set up as of a month or so. What I want is for the two actual machines to be networked through wired ethernet (through a portable "Ubiquiti USW-FLEX-MINI UniFi USW Flex Mini Managed Switch"). With the ethernet wires plugged in I see the status bar connection icon in the guest and it says it's connected and shows tiny amounts of traffic. I don't see icon on host, not sure if that matters or is a function of the host passing it on. Oddly, and worryingly to me, I don't see the icon on the Juno fallback machine.

I had thought I could just set up fixed IPv4 addresses for the ethernet interfaces on both physical machines using private address space not being used by my wifi and, with the right netmask and same network and broadcast addresses, and perhaps having to declare a route I would have an wired network between the machines.
But so much has changed with everything managed by NetworkManager in System Settings now that I'm not passing go.

I had assumed that I might have to do a bit more in the guest/host configuration to enable the guest to see the fallback machine though that's not absolutely vital for me as this is mainly for overnight backups from the guest to the fallback machine done when the guest is down.

I can happily supply more information of course and, cautiously, tweak things, but ...

first edit starts here, replying to comment from vidarlo

Not sure why I lost "but I am worried about messing up a working host/guest machine." OK. Many thanks for helping vidarlo.

"What doesn't work when you simply configure static IP's?"

Sadly, I am not confident of how to do that! That's not helped by not seeing the wired connection icon on the task manager on Juno, the fallback machine and being worried about wrecking things for the Host/Guest pass through on the Tux machine. If you are confident of some instructions that work for [K]ubuntu 25.10 do please point me to them and I will try to follow them.

"What is your configuration like? Please provide output of ip a, ip route when you have it configured statically, ..." I am guessing there is no point in me giving those until I pass go.

"... and tell us what doesn't work." What doesn't work at step #1 for me as far as I am concerned is that the wired connection icon doesn't come up on the Juno machine yet it does on the guest on the other machine. That's not a cable issue as I have swapped the cables over and the situation stays the same. In case it helps ip a on Juno gives:

Very happy to do anything more on the fallback machine and get any diagnostics on the host machine. Many thanks, Chris

"Could you please clarify, because it's not very clear from what you wrote: what setup exactly do you want to have (involving both hosts and guest), and what is the current state." Sorry, hard to know how much to say. I want both machines to continue to access whatever wifi network I am using (I travel). The guest currently sees that through the default pass through from the host on Tux.

What I want to add to that is a static route across wired ethernet through that switch between the two physical machines. I will use that mainly to do nightly backups from the Tux host with the guest shut down that would run, like my current ones backing up to external USB drives on Tux, from cron jobs. I assume that the static wired route will automatically take precedence over the wifi connection so ensuring that the backup doesn't waste wifi/internet bandwidth.

If possible, it would be nice also to "see" the fallback machine (Juno) from the running guest on Tux through ssh and, ideally VNC or similar, so that I can control Juno from the guest without having to change my seat and keyboard.

I only have the two machines at present but some time in 2026 I will have a more stable base and will wire in powerful desktop on the static network. That machine will have a host/guest configuration matching the current on on Tux.

The current state is that both machines currently access wifi fine still, including the guest on Tux but I gave up even starting to configure the static IP addresses for the ethernet adaptors or any route as I found so much on the internet that was either contradictory of other things, or too technical for me, or obviously way out of date.

"When you click on the Network Manager icon in the status bar, what connections do you see and how are they configured (use "Modify Connections" option to investigate)?" I don't see any such icon on Juno. In the guest on Tux I do but there is no "Modify Connections" it does show "Wired connection 1" with IP address 192.168.1.223 device name enp1s0 and gateway and nameserver both as 192.168.1.1 connection speed 0Bits/sec and MAC 52:54:00:4C:D6:F3. I assume that's a masqueraded wired address provided by the host, the MAC address fits with "vnet3" in the output of ip a on the host (below).

If I go to System Settings and "Wi-Fi & Networking" in the host I see various wi-fi connections including the one I am using now in infrastruccture mode with IPv4 just staying "Automatic" but ip a gives:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

and ip route gives

192.168.122.0/24 dev virbr0 proto kernel scope link src 192.168.122.1 

"And how is the networking for guest configured in virt-manager?"

<interface type="network">
  <mac address="52:54:00:4c:d6:f3"/>
  <source network="default" portid="2dcb5860-a23c-4a2f-9491-0f99e905b360" bridge="virbr0"/>

  <model type="virtio"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>

That seems to fit the guest and host information.

I think all this is saying that the host/guest passthrough is set up conventionally and is working and that the wifi/internet connection is using the local private IP name space of 192.168.122.* so I was guessing that if I used any other private name space, ideally one that few ISPs use, a static wired network between the machines wouldn't collide with the wifi/internet connection. (Though I suspect that I would have to add something to the host configuration to add the wired connection to pass through separately from the wifi one?)

Am I understanding things correctly so far? Is this clarifying for yourselves? Any instructions now how I might set up a static wired route between the two machines at least for the host and not clashing with the host providing the passthrough to the guest?

Thanks again both, Chris

Edit replying to user68186

"Does the "mini managed switch" run a DHCP server? Is the switch connected to the WiFi router by Ethernet cable? Does the switch provide IP addresses? Are those IP addresses in the same range as the WiFi router?"

Web page is: https://uk.store.ui.com/uk/en/products/usw-flex-mini. I believe no DHCP. That's deliberate as I didn't want two DHCP servers in the mix. I know you can configure some switches and routers to protect IP name ranges from each other but as I move around a fair bit at the moment I wanted to go for simple static routing. and no, it's not connected to the wi-fi/internet router which may sometimes be not mine and currently none of them are in wired connecting distance of the computers. That means I have to choose the IP range manually to avoid the collisions.

edit replying to user68186

"Thanks! Can you change the "Wired Connection 1" in Tux so that it is "Shared with another computer?" Then it will assign an IP address from a different range (different from your WiFi). It will also dynamically assign an IP address to Juno. Try this and let me know. You can also try this by directly connecting Tux and Juno using a single Ethernet cable totally bypassing the switch. See this answer for a similar question." So in System Settings > Wi-Fi & Networking on Tux I created using the nearest option to that that I could see so "+" "Wired Ethernet (shared)" and then "+ Create" and that gave me a new connection named "New 802-3-ethernet connection" and in the "IPv4" tab the Method is "Shared to other computers" and it works. Has allocated 192.168.1.3 to Tux and 192.168.1.13 to Juno and certainly I can ping between the two in either direction. Brilliant, thanks! That is brilliant and embarrassingly simple.

Re single wire: yes, I do know that's now possible, no more crossover wires! But I wanted my solution to allow for more than two machines.

One, I hope final, question: I guess those addresses are dynamic. Is there a way I can fix them. I suppose that would fail if I were using another wifi/internet router which used in the 192.168.1.* address space. However, I guess I can use ip route every time I move and see what IP addresses have been allocated and tweak my backup scripts to that. Now to set up scp and the necesary scripts!

Thanks user68186 and all.

I was running snap remove cups on my Ubuntu 22.04 system because I wanted to re-install "cups" directly via "apt" instead of running it as a snap. While this snap remove cups was running, I wanted to kill a different process, but I accidentally chose the PID for that snap remove cups process, and that process was killed.

Now, I get the following output for the following commands (and note that I'm running all these commands as root):

snap remove cups
    error: snap "cups" has "remove-snap" change in progress
snap remove cups --purge
    error: snap "cups" has "remove-snap" change in progress
snap disable cups
    error: cannot disable "cups": snap "cups" already disabled 
snap enable cups
    error: snap "cups" has "remove-snap" change in progress

    snap "cups" is already installed, see 'snap help refresh'

When I run snap abort 29, this doesn't produce any output and exits with return code 0, and it doesn't change anything, and the snap commands that I listed above still give the same results.

I rebooted, and this doesn't change anything, either; I still get the same results for all those snap commands.

Obviously, my accidental killing of that snap remove cups process caused this situation.

Does anyone know how I can fix this and get the "cups" snap to be totally removed?

Thank you in advance.

UPDATE: Also, running snap refresh doesn't fix this problem. The refresh succeeds with return code 0, and all the above snap commands still return the same results.

FURTHER UPDATE: I'm hoping for a solution to this problem which doesn't involve something as drastic as a complete uninstall-followed-by-reinstall of snap ... if at all possible.

After startup and typing the password I get a screen about a system mistake on my Xubuntu laptop. I can't see what mistake it is about. Where can I see it? And what to do further? My Xubuntu version: Xubuntu 25.10

I have Thunderbird 140 and I cannot send or receive mail. I have wiped the computer 3 times and each time it sends and receives about 3 times and then just stops. I have a Intel i7 with 1TB storage and 16GB memory. I tried Evolution, but that wouldn't work either.

I have Ububtu 2403.LTS which came with Thunderbird. I didn't get any e-mails at all, Thunderbird simply checked the smpt and went silent, with no new messages. I checked the message count against my Linux phone which had 4 new messages. Version 140 of Thunderbird is used.

I'm having about half of my single toGNOMEuchpad taps ("tap-to-click") ignored on Ubuntu 23.04 GNOME. It was working fine on 22.10 on same laptop right before upgrade. I imagine there is a sensitivity adjustment that can be made, although it is not in settings. I've searched around, but cannot find a solution. How can I adjust the tap sensitivity?

Second question: libinput reports tap-to-click is disabled, yet it is enabled in GNOME. settings, so does GNOME interpret tap-to-click in software or some other way?

Ubuntu Settings:

I'm switching from Linux Mint to Ubuntu, having created an installer of 21.10 on a USB stick. When booting into the "Try Ubuntu" mode, my wifi adapter didn't work out of the box. So I went to the Additional Drivers section of the Software & Updates application and enabled the proprietary driver (Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source) for a BCM4352 802.11ac adapter.

That works like a charm. After enabling the driver, I can connect to a wifi network, browse the internet, etc... This is exactly what I had to do in Linux Mint as well, which isn't surprising since that one is based on Ubuntu.

So after confirming that wifi worked, I installed Ubuntu. I picked the option with the additional software and also checked the checkbox to install third party drivers. After the installation completes and I reboot into the new installation, I try to repeat the steps of enabling the wifi adapter, but when I click on Apply Changes, I get the error:

pk-client-error-quark: Cannot download packages whilst offline (257)

To try and fix the issue, I've plugged in the installation USB, went to the Ubuntu Software tab and made sure that it is checked in the "Installable from CD-ROM/DVD" section. No good. So I tested installing a random package from the command line with apt-get and the error message suggested that it was looking in /media/cdrom for the installation disk, where it was mounted in /media/username/[something]. So I created a link from the mount point to /media/cdrom and the command line installation worked.

But, activating the proprietary driver still returns the same error and it won't let me activate it.

It's a bit baffling that the process works perfectly fine in the "Try Ubuntu" mode, but it completely refuses to do the same thing when installed to disk.

I have a bunch of computers I'm trying to connect to each other with some random router I found lying around. I have all the machines connected to the router and have given them fixed IPs. I have used ssh before and I thought it would be super easy just remote-control the other machines with ssh, but for some reason I get this "permission denied, please try again"-error.

I've tried making firewall adjustments, various conformations of the /.ssh/sshhd_config, but nothing works. I'm at least sure that the machines can "see" each other, since when I enter the IP I'm asked for the password of a username@machinename of the computer I know I'm connecting to.

I'm worried that I may have some configurations to do with my router, or that I'm somehow giving bad static IPs, but in those regards I don't have a first clue about what to do. Do you guys have any other suggestions as to what might be wrong?

Oh yeah, I'm using Ubuntu 20.04.

I like turning off the monitor when I don't need it, to reduce eyestrain and energy consumption (e. g. when only listening to music). On X11, I have been using the sleep 0.5; xset dpms force off shell command and assigned it a custom keyboard shortcut.

Recently, I've switched my entire workflow to Wayland, and the xset dpms commands apparently don't work on this platform - output says server does not have an extension for dpms option.

Is there an alternative method which I can use to turn off the monitor on Wayland?

So for some reason I haven't been able to open the terminal in ubuntu anymore, I already tried the solutions from these threads

Terminal does not start on Remote Desktop; how to fix it?

Can't open terminal in Ubuntu 18.04 after upgrade from 17.10

and none of them have worked for me.

With the solution where I need to run locale.gen,I kept getting an error that I did not have an application to open it properly, I then got prompted to downloaded the Games app but it couldn't open it either (wasn't surprised)

With the solutions where I'm being told to run some commands with the terminal, it's not possible as I can't even open the terminal (and I'm not to sure what the gnome terminal is, I tried searching for it on my system but it just led me back to the regular terminal)all I can do is press on the terminal icon and then nothing happens. I'm pretty new to using ubuntu so I was hoping I could find some help here. I am running ubuntu 18.04

thanks

I cant able to use my Touch pad as well us USB mouse once i suspend or put my laptop on hibernate. how do i fix it?

once laptop went sleep i cant able perform Button Click using Touch Pad / USB Mouse.. even my laptop having touch screen that too not working. only Button Click event. otherwise scrolling and all works fine..

Was thinking of using a joycon as a presenter's clicker. A quick test on my Android phone shows it paired just fine via Bluetooth, though the input is a bit slow and laggy.

However, in 16.10 the Device Search doesn't seem to discover the joycon in sync mode. I've paired bluetooth headphones to this computer successfully, so I don't think it's the hardware. Are there settings or libraries I need to tweak to fix this?

Yesterday I was watching a video on youtube and suddenly my laptop got frozen.
I wasn't able to even move my cursor, so I gave it 10 min and after no response, I pressed the shutdown button for 5 seconds and rebooted my machine.

When it rebooted, it presented me the following screen:

Since than I've been searching the internet for any way to get pass this with absolute no luck.

Bellow I'll leave all the steps I've tried so far:
[First I was having problems enabling networking so these were the steps that helped me:]

• selecting the option Advanced options for Ubuntu

• choosing the option Ubuntu, with Linux 4.4.0-66-generic (recover mode)
• selecting the option Enable networking from the Recovery Menu

• when it finishes and returns to the Recovery Menu, I select the option Drop to root shell prompt

• and then running the following commands with my Ethernet cable plugged in did the trick:

Commands:

/etc/init.d/networking start
echo "nameserver 8.8.8.8" > /etc/resolv.conf

Then I followed this answer referring to this link and repeated the commands for about 10 times each in random order as described in the post:

apt-get update
dpkg --configure -a
apt-get dist-upgrade
apt-get -f install

And I also tried this: answer

cd /etc/dhcp/dhclient-enter-hooks.d
sudo rm debug
sudo ln -s ../debug.dbkg-new debug
cd /etc/dhcp/dhclient-exit-hooks.d
sudo rm debug
sudo ln -s ../debug.dbkg-new debug

After all of that, my machine is still showing the screen in the first image. At this point I don't know what more can I try so I really need some light on this.

Don't know if this is relevant but this is my uname -a:

Linux rm-pc 4.4.0-66-generic #87-Ubuntu SMP Fri Mar 3 15:29:05 UTC 2017 x86_64 x86_64 GNU/Linux

Also when I executed journalctl -xb and this are all the red lines in the code:

I've recently purchased an Asus E202S desktop computer and tried to install Ubuntu 16.04 on it. I had no problems to install or make a dualboot with Windows 10, but the real problems started to show up almost an hour after I've finished the system installation.

Basically, my wifi is periodically "freezing" (The wifi signal shows that everything is ok, but I do not have Internet connection), and I am forced to restart the network-manager. Even after restarting the manager, sometimes my wifi won't show up on the list of available networks or will not work at all. I don't have any of these problems on Windows 10, and also my Internet speed is much faster.

I've been trying to find the problem for almost one week, and here are some of the dozens of cases which seemed to be the closest to mine:

It makes connection a little bit stable, with this driver I can upload 30-40 mb instead of only 5mb, but after upload freezes again.

b.) If I boot with older kernel (3.19.8) networking is working perfect and two times faster. But!, only in shell because Xorg fail to start on this kernel with error:

 [   113.698] 003f:1bdf: 3F ILLEGAL EXTENDED X86 OPCODE!

 Fatal server error:

Can anyone help me to solve these issues?

I'm pretty new to linux, but I did my best to obtain all information regarding my issue so maybe someone could help out.

I have an HP Pavilion dv6 Notebook, with Ubuntu 14.04 manually installed.

The log of lspci | grep VGA is:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev ff)

I need to disable the Intel graphic card and only use my NVIDIA, as currently I'm pretty sure the NVIDIA is not in use.

From lsmod I see it uses the i915 module. I tried blacklisting that module in /etc/modprobe.d/blacklist.conf but that didn't really work because i still couldn't use the NVIDIA card for display.

I can't enable NVIDIA from BIOS, nor disable intel.

So what I'm looking for is a solution allowing me to use the power of my NVIDIA laptop, as currently the graphics are pretty bad due to the intel usage.

Thanks

I just switched from xmms to Audacious and I'm trying to import the Winamp presets but without success so far. I checked various guides but none of them works. I have a file named eq.preset but If I try to import it to Audacious I get an error:

Error importing Winamp EQF file 'file:///home/edem/winamp_presets'

I think that either this is a bug some people mentioned about Audacious or I'm using the wrong file. It looks like this:

[Presets]
Preset0=(WinAmp) Classical
Preset1=(WinAmp) Club
Preset2=(WinAmp) Dance
Preset3=(WinAmp) Full Bass

Since I'm using a rather new version (3.3.4) I think I'm using a wrong preset file. Can you help me out on this one?

I've installed a version of Java. How can we set the $JAVA_HOME environment variable correctly?
