I am a new Ubuntu user. I would like to install Ubuntu 25.40 in WSL on Windows 11. Please advise how can T do that.
Until recent Ubuntu updates everything was ok ...
Now however, not so much ..
VirtualBox. I have an Ubuntu server with static IP via netplan. I have an Ubuntu VM (DHCP/DNS) with a static IP created on a Windows machine that runs with the assigned static IP. However when it's transferred to the server, the VM's IP/interface is consistently down and I cannot get it to come up. Both the server and the VM are both running the same version of Ubuntu.
What am I missing?
I 've a dual boot system with Windows 11 (Emule) and Ubuntu 24.04 (Amule). As I change O.S. the ip configuration for IPV4 change and I can't use the Emule ports because i've set them with the ipv4 that workd in Ubuntu. How to have a unique IPV4 that works as for Windows as for Ubuntu?
I'm trying to find an audio graphic equalizer for live audio editing. My laptop has two USB audio adapters one for input (as a microphone) the other for analogue output (as headphones) as well as the standard mic / headphones port.
I've tried using Easy Effects with PipeWire and can do either:
audio in for recording and manipulate using the input graphic equalizer.
audio out from an app like VLC and manipulate the output graphic equalizer
But so far I can't find a way to connect the input to the output. If you know a way to do this with Easy Effects then I'd love to try it. Alternatively is there another app that will run on Ubuntu?
I am trying to use the sound recorder from GNOME to record mp3 audio files for my lectures, but for whatever reason, it won't start recording and is simply stuck at 0:00. When I try to stop it or trash it, it just will acknowledge I clicked it, but won't actually take the action to do it and becomes essentially soft locked until I kill the task.
The sound recorder works fine when I record in FLAC, but for the purposes of what I am doing, FLAC isn't an option and I'd rather not convert it to MP3 every time. Is there a solution to this?
I know this topic if often coming up with other people. But I haven't found the solution in their posts.
In my Ubuntu 24.04, I decided to change the G810 profile because all it was doing was turning white all keys. I wanted to change this using key groups. But it totally stopped working. Nothing happens. Keyboard backlit is black or not working at all.
I checked a few internet suggestions but still nothing.
I checked the vendor ID and product ID in the command line and it matches 046d c336 wthat I had put in my g810-profile.
I am not detecting any UDEV rules for any G8*.
I am not detecting any services for any G8*
I changed back my profile to just "a ffffff" but still does nothing.
I am not detecting any error messages in journalctl following this.
I am pressing the backlight button twice but nothing.
There is a /etc/g810-led/profile (just above command line) and /etc/g810-led/reboot (no command line).
I tried reinstalling it.
Following some internet suggestions, I tried creating a UDEV rule and the service but it was causing errors in the journalctl. So I removed them.
My mouse g203 light is cycling but I have not done anything for it to work. It started working on day one that I plugged it.
Last time, it was doing the same thing than a few days later, it was working. No idea why and how.
I purchased a new Framework 13 laptop a few weeks ago and set it up with Kubuntu. All has been working well except for when I tried to take calls with my airpods. I could hear fine through them, but the mic didn't work. After a lot of troubleshooting, I determined that the issue had to do with the fact that I was running PulseAudio and not PipeWire, so I followed this tutorial and was able to fix the problem. Unfortunately, in the process I somehow lost access to my speakers and my headphone port, as now when I disconnect my airpods, the only audio option is Dummy Output.
I have no idea what caused this and was up until 2 am last night trying various fixes with no luck. I'm wondering if maybe the issue is that I'm running an older version of pipewire (1.0.7) as I've seen a newer stable build in some forum posts (1.4.7). I'm open to anything though, this is my first time with Linux as a former Mac user, so I'm still getting used to it.
Audio tab under System Settings, no Bluetooth:

When I run pactl info
Server Name: PulseAudio (on PipeWire 1.0.7)
Server Version: 15.0.0
Let me know what other information would be helpful.
Edit:
I think I might have identified the problem though still unclear on what the fix is. When I type aplay -l into the Konsole, I am met with this:
**** List of PLAYBACK Hardware Devices ****
ALSA lib conf.c:2012:(_snd_config_load_with_include) _toplevel_:2:0:Unexpected end of file
ALSA lib conf.c:4120:(config_file_open) /etc/alsa/conf.d/pipewire-jack-x86_64-linux-gnu.conf may be old or corrupted: consider to remove or fix it
ALSA lib conf.c:4042:(snd_config_hooks_call) function snd_config_hook_load returned error: Invalid argument
ALSA lib conf.c:4649:(snd_config_update_r) hooks failed, removing configuration
aplay: device_list:286: control open (0): Invalid argument
So there seems to be something wrong with my ALSA config. How would I go about fixing or removing it?
If I suspend and log back in after a short amount of time there's no problems, but if the laptop stays in suspend more than an hour or so I can not log back in. I enter the password and the wheel spins and spins but I can not get back to my desktop.I have to reboot to be able to get back into my account. What could be causing this? This started to happen pretty recently.
In the cli I have had this happen twice today on two different PCs. In the cli I can run simple commands like cd or ls -a with no issues. Then I run the update and then upgrade and reboot. I open the terminal and run the same commands I get permission denied. I am at a loss on this.
My machine is a HP Probook 4540s. My version is 24.04.4 LTS. The internal disk is 500 GB with a GUID partioning table. I have connected a number of disks from my old machine, an old MacBook Pro running 10.15.7, Catalina.
When I run Files I see three disks, an empty one called BIG DISK, 1TB, with MBR partitioning, PO-40595, 320GB with GUID partitioning table, and a disk called TM, also 1 TB, which once was used as a Time Machine (backup unit for Mac) and has GUID partitioning. I haven't reformatted the Time Machine disk yet.
But I have a fourth disk, 2TB with GUID partitioning, formatted on the Linux machine and I can't see that disk in Files. How do I make it visible?
It's a while since I used linux (Ubuntu) and I'm a bit out of touch so forgive the very basic nature of my query.

I successfully installed Ubuntu 24.04 LTS and I needed to roll back to kernel 6.8 on my 2013 MacPro 6.1 (Trash Can).
I managed to get everything working which was, the Dual D700 AMD GPUs, a 1TB NVMe drive for the Ubutnu OS and a Pegasus2 R4 Thunderbolt External HD.
I was wondering if there is a fast/easy method to search for apps to install that will work on my old machine?
For example, Blender no longer supports Open CL, I need to go way back in their versioning to find one that used it, etc.
Thanks
I recently installed Ubuntu 24.04.4 LTS on my windows pc. I added the efi entries on my main drive containing windows and wanted to dual boot, such that grub loads on default and I can select whether I want to boot into Ubuntu or Windows. But it boots to windows by default.
I tried changing the boot order with efibootmgr and changed the first priority to Ubuntu Grub, but on restart, it boots to windows, the order reverses back.
I tried the same in Windows with bcdedit with the same result.
I suspect it is something to do with my motherboard, which forces me too boot to Windows. Renaming the windows EFI file leads to failure to boot. The only way to boot to Ubuntu is with the f11 boot menu.
The bios also has a weird drive selection, with no proper names. Boot priority lists stuff like UEFI USB Hard Drive, USB Hard Drive, CD ROM, Network Drive, etc, instead of the actual drive names. The drive with windows shows Windows Boot Manager, but no such luck with Ubuntu.
I am very new to OS flashing and BIOS stuff, and am very scared to brick my PC. But I still want to have the grub menu by default. I have listed my specs below, Any help would be appreciated.
OS:
Ubuntu 24.04.4 LTS on 100GB partition of a 250GB HDD
Microsoft Windows 11 22H2 on a partition of a 500GB SSD
Motherboard: MSI B70 M-E DDR5 (Secure Boot Disabled)
Drive Setup: 
I’m running Ubuntu 24.04 inside VirtualBox, and I’m experiencing persistent screen flickering inside the guest OS. The flickering happens during normal desktop use (moving windows, opening menus, switching workspaces, etc.). It continues even after installing the correct VirtualBox Guest Additions packages.
This is not a hardware issue, since the host system is stable and only the VM shows the flicker.
What has already been tried
1. Installed the correct VirtualBox guest drivers.
I installed the proper packages for Ubuntu 24.04:
sudo apt update
sudo apt install virtualbox-guest-utils virtualbox-guest-x11
Video Memory: 128 MB
3D Video acceleration: off
Switched to Ubuntu on Xorg - didn't help
Ubuntu 24.04
I have recently bought a 2.5 gig network card when i just plugged it in it was limited to 100mb, i suspect i need to install some drivers, from searching around the internet a bunch i think its the r8125 driver i need.
When following the packaging i find this page from RealTek with a script. (i'm getting mixed signals, the website says kernel versions up to 6.12 (I'm running 6.8.0-101) but in the readme it says 2.6.x and 2.4.x. What am i missing there)
When i try to run the script it simply gives this message:
Check old driver and unload it.
Build the module and install
make: *** No rule to make target 'all'. Stop
This is the out put of sudo lshw -C network

I would like someone to guide me pretty diligently through how to install the drivers i need.

After running apt install r8125-dmks i got this ethtool output.

Can I open/view multiple MBOX files at once instead of loading them individually? Please suggest an easy solution.
Any advice would be great. I am trying to install Ubuntu 22.04.5 on a Dell workstation. I previously was able to install 24.04 dual boot with windows easily with no issues, however a software package I need to use is only compatible with 22. So I wiped that drive and tried to install 22.04. Everything goes fine until the very end of installation, the installer crashes at the same point when it reaches, Installing Packages. After that I cannot restart installation and have to reboot to try again. I have disabled secure boot and tried booting via the safe graphics mode with no success. I have tried installing it on three different SSDs and even removed the windows installation but still haven’t been successful. Using 24 is not an option. One thing to note is that after every crash when it goes to report the bug it cannot because it says my package is unofficial. Idk what that means I am getting the ISO direct from Ubuntu and have tried redownlading/reflashing multiple times. Thank you.
Edit: I am installing using a usb drive and balenaEtcher and validated the checksums. Intel XeonR w3-2535 with 64 gab of DDR5 RAM. Precision 5860 tower. The crash dialog doesn’t load properly it says there is a problem in ubiquity, but I’ve attached logs from the installer folder. https://docs.google.com/document/d/1-G07jqBMVjH74QK4LKCE8TLrpyJAHlIVAEFF1t6osts/edit?usp=drivesdk

I use Thunderbird for several of my email accounts.
Today I have new messages as usual, but they don't show up in the list of emails (middle panel) so I cannot open them.
Strangely, the count of unread messages shown next to the inbox is correct and updated : when I open emails in the webmail, the number of unread emails is the same as the count in Thunderbird, and it gets correctly updated in Thunderbird. So it seems that Thunderbird is able to download the emails, it just does not show them. Additionally this happens for two different email accounts (with different providers), so it's not caused by something specific to the settings of the account.
I'm on Ubuntu 24.04, using the default snap package, currently version 140.2.0esr-3.
What can I do to solve, or at least diagnose the issue?
When I open the terminal, the window appears without the ability to write in it. I cannot type, and I also do not see the directory. You can see the screenshot:
I have already tried killing all running processes and restarting the computer. Additionally I attempted to reset the terminal. How do I fix this?

What happened with my drive? Is it already broken? Is there any way to fix this?
As the title states I'd like to obfuscate my wifi's credentials and know that wpa supplicant has wpa_passphrase to do this.
My question is can I place wpa_passphrase's hashed output in the entry for password of the network-config file that Ubuntu Server 20.04 LTS uses?
Or is there a similar command to hash the psk for cloud-init files that I should be using instead?

I am creating an unattended installation using preseed for Ubuntu Desktop 18.04.4, and I want to install openssh-server (openssh-sftp-server for desktop) making it actually possible to ssh after installation is completed.
I have tried using commands such as: pkgsel/include,ubiquity/success_command and preseed/late_command without any luck.
The preseed does not install software nor does it update the packages.

So in general it looks like there are no errors, but I am unable to verify whether I actually made the connection or not. The biggest issue is that no ppp0 device shows up when I execute ip link:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 6c:f0:49:70:55:16 brd ff:ff:ff:ff:ff:ff
Because of that I am unable do define which traffic should go through the VPN server. How can I ensure that ppp0 device shows up and the IP address is assigned to it by the DHCP/VPN server?
I'm trying to set up an Ubuntu Server 16.04 in a VM to act as a gateway for traffic to be tunnelled through a connection via OpenVPN.
The concept is that this VM has a static IP and clients on my network can set that IP as their gateway and the VM should route traffic through the OpenVPN connection. All other clients default via DHCP to the primary gateway.
I followed this webpage as a guide and adapted it to my purposes, however when I set a client to use this tunnel gateway VM as the default gateway it cannot connect to anything outbound.
Here is my configuration:
Tunnel Gateway (Running Ubuntu Server 16.04)
IP: 192.168.2.3
Gateway: 192.168.2.1 (This is the primary gateway that DHCP clients get.)
Contents of /etc/rc.local:
# /etc/rc.local
# Default policy to drop all incoming packets
iptables -P INPUT DROP
iptables -P FORWARD DROP
# Accept incoming packets from localhost and the LAN interface
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -i ens160 -j ACCEPT
# Accept incoming packets from the WAN if the router initiated
# the connection
iptables -A INPUT -i tun0 -m conntrack \
--ctstate ESTABLISHED,RELATED -j ACCEPT
# Forward LAN packets to the WAN
iptables -A FORWARD -i ens160 -o tun0 -j ACCEPT
# Forward WAN packets to the LAN if the LAN initiated the
# connection
iptables -A FORWARD -i tun0 -o ens160 -m conntrack \
--ctstate ESTABLISHED,RELATED -j ACCEPT
# NAT traffic going out the WAN interface
iptables -t nat -A POSTROUTING -o tun0 -j MASQUERADE
# rc.local needs to exit with 0
exit 0
tun0 is established via systemctl on system start with a config file. Once established the tunnel gateway VM has no problem sending traffic through it by default.
The client is configured like this:
IP: 192.168.2.42
Default Gateway: 192.168.2.3
I've gotten RDP through Remmina to connect to a Windows 8 guest running locally on my Ubuntu 17.04 installation on my home network using the Bridged Adapter setting in the VirtualBox Manager.
The problem I have is that I would like to be able to connect to the Windows 8 guest on the same machine when I'm at work. Unfortunately, there the Bridged Adapter doesn't work because of internal IT rules; the guest OS is blocked from seeing the internet.
My current thinking is that I can create a second connection in the VirtualBox Manager, a Host-Only Adapter, and use that to connect from my host to into the virtual machine. That way the guest OS can see the internet through the first connection via NAT and I can log into the guest through the host-only adapter.
Unfortunately, trying this, Remmina won't connect to the guest OS. I can see the local vboxnet0 network in the host ifconfig and the guest OS reports an IP address for the connection. I'm assuming, though, that Remmina is asking the internet to the connect to the IP address, rather than trying to connect to the guest running locally. Is there a way to accomplish this successfully? Or is there a better solution for what I'm trying to do?
Ultimately I'm hoping to use RDP to run individual applications on the host rather than having to turn on and log into Windows every time I need to run a Windows-specific application. This is mainly to be able to use Office365 on my regular Ubuntu installation.
Thanks in advance for your time, consideration, and advice. I'm looking forward to hearing back.
Ok, I know there are many questions about this topic, but I can't found a convince answer (fixing the problem or not).
Recently I bought an SSD drive and installed in main SATA (hd0), I've replaced my cd/dvd drive with old hdd drive, using a caddy adapter.
Now I've installed Ubuntu on SSD and windows 10 on hdd.
The problem is on the boot, when I select windows in grub menu I'm faced with this error: cannot get C/H/S values.
I can't set hdd boot on BIOS because it's expected a ODD driver.
I have a Dell Inspiron 14R-5437.
Is there a workaround for this?
I've installed fglrx driver on my Asus k52je laptop with mobility radeon hd 5470 using additional drivers window in ubuntu. I get black screen after reboot. When I hold power button i can barely see shutdown, restart, lock and suspend icons and I am able to choose one. I've also tried building driver from sources and installing from xorg-edgers. None of those worked. Is there any workaround?
EDIT:
It seems I can use external monitor without issues
I suspect there might be bad sector on a disk. I used ext3 filesystem.
What tool is the best equivalent of the error checking tool of Windows?
