I try to follow this tutorial but I want to be able to close the ssh session. so I'd need a way to have the setup work in the background and I'll just check hours later if it went through.
if I had setid or nohup or similar in initramfs I could do it.
When doing sudo apt update && sudo apt upgrade, I get the following error:
N: Skipping acquire of configured file 'stable/binary-i386/Packages' as repository 'https://download.docker.com/linux/ubuntu noble InRelease' doesn't support architecture 'i386'
I'm not sure why I'm getting this error. I followed the instructions for the Docker Desktop installation. The app runs well and I've used it for some tasks, so everything seems to be working well, but seeing this message every time I update is annoying.
How do I remove it?
I am aware of this post. I installed Ubuntu 24.04.3 LTS on my computer which has Broadcom Inc. and subsidiaries BCM4360 802.11ac Dual Band Wireless Network Adapter [14e4:43a0] (rev 03). I do not have Wifi. I tried the post I mentioned earlier, used
sudo apt install broadcom-sta-dkms
and it worked! I had Wifi until I rebooted my machine. Then, again can't see Wifi. Followed the instructions to purge broadcom-sta-dkms, and try to reinstall it but I get this error:
he following packages have unmet dependencies:
dkms : Breaks: broadcom-sta-dkms (< 6.30.223.271-25.1~) but 6.30.223.271-23ubuntu1.1 is to be installed
E: Unable to correct problems, you have held broken packages.
Does anybody know what to do at this stage?
I have a 14" laptop screen with 1920x1080 resolution, thus I'm using %125 scaling (I didn't know about scaling before because I didn't have this resolution for the same screen size on my previous laptop). I wonder if this is only effective for scaling desktop graphics or it is also effective for videos. I'm curious because videos wouldn't need scaling but maybe the technology cannot separate videos from other desktop elements. Why would I sacrifice performance whilst watching a video on youtube or from a non-streaming media file?
Having finally managed to get Ubuntu 24.04 installed, it boots fine and I am gradually getting some software added. It is a dual boot with Windows 11, and the problem I have now is that the Ubuntu boot manager shows the option to boot to Windows, but always fails with this screen.
This shows nearly 30 messages saying "prohibited by secure boot policy" followed by "no such device" and then "file /efi/Microsoft/Boot/bootmgfw.efi not found". From what I have found out, this should work with Secure Boot active. Is this simply telling me that's wrong, or could there be a different reason why it is failing?
I installed Ubuntu 25.10 yesterday and before doing anything else I noticed the notification for Software Updater on top right of the screen. I click to show updates option, software updater opens up but when I wanted to remove some apps that I don't need to update I get this not responding message. It doesn't go away even if I select to wait many times. I bought this laptop (Thinkpad T495) second hand but it doesn't seem to have any problem other than this. Is this a bug of 25.10?
I have a Thinkpad T495. I installed Ubuntu 25.10 on it with a USB drive. I want to do a memtest now, but it doesn't boot from the same USB drive. Nothing happens when I select USB drive in the boot menu and press Enter. I also moved it up to the top in BIOS boot options, but it's still loading Ubuntu at startup. What should I do?
The goal is to enable fingerprint authentication for sudo, but disable it for initial login. This question has been asked a few times, but the answers available here no longer work for Ubuntu 25.10.
Some other answers mentioned that the following setting is available to configure this, however attempting to set it fails:
$ sudo -u gdm dbus-launch gsettings set org.gnome.login-screen enable-fingerprint-authentication false
Authorization required, but no authorization protocol specified

You can avoid the latter errors (process:) by changing the permission bits on the relevant files it changes (idea is to switch it back afterwards - not sure if there will be other issues down the line with that). However, you still end up with the following error when running dbus-launch:
Authorization required, but no authorization protocol specified
What is the correct way to set this up? How do I provide a mechanism to authenticate the gdm user's request?
I followed a guide for updating the PAM configuration as well, but it didn't work and I'm somewhat nervous about making changes there. Will give it another go and keep some notes if absolutely necessary, but I would rather use the functionality above if it is possible to get it working.
I'm installing Ubuntu for the first time and i had an issue with the password and needed to change it, i got into the recovery boot menue (the magenta one) and i cant drop to the desired option... Neither my keyboard or my mouse work and I'm at loss atm (I dound a similar question in the mint forum but they have server problems atm and the magenta is really horrible) Anyways, pls lmk your thoughts! I wouldve added a picture but I'm too new for that:/
I installed the latest version of Ubuntu on a Dell Latitude 7340. Everything works fine except for the webcam and its microphone. Ubuntu doesn't detect anything. I managed to get the camera working after a first attempt, but I replaced the SSD and then reinstalled everything from the same ISO, but this time I can't get it to work. Do you have any suggestions?

I just got a new PC and installed dual boot Windows and Ubuntu 24.04. Everything seemed to be going well until I got some disk space issues. I tracked this down to /var/log syslog . and kern.log which are showing the following issues:
syslog:

Initially both logs were up to 45gb each, resulting in Ubuntu not being able to boot up. Journal logs are also fairly sizable at 4GB, but less of an immediate issue. Syslog and kern.log are still both creeping up in size, but I've cleared them with:
sudo sh -c 'echo > /var/log/syslog'
sudo sh -c 'echo > /var/log/kern.log'
I'm aware this is only temporarily keeping things going. I've looked into logrotate and may set that up, but it seems that there's a broader issue with "pcieport 0000:00:1c.0: AER". I don't know what this is though or have any idea of how to fix it.
Is anyone able to help me with this? My command line skills aren't great and I don't really have and understanding of what's going on with these processes other than something with pcieport is throwing up unresolved errors and they're building up and taking over memory that I want to use for other things.
I'd really appreciate any clear advice, explanations or solutions.

I installed dkms and ran it, but it returned nothing, so I take it that means I don't have it.

I'm using ubuntu 22.04 and I have the following configuration acting as a router
WAN - DHCP (enp2s0)
LAN1 - 10.42.1.1/24 (enp1s0)
LAN2 - 10.42.2.1/24 (enp1s0.2)
I am using Network Manager to share WAN with LAN1 and LAN2 using the ipv4.method shared.
Everything works great except LAN1 can't access LAN2.
For example, from a client in LAN1 I get
$ ping 10.42.2.175
PING 10.42.2.175 (10.42.2.175) 56(84) bytes of data.

nc: connect to 10.42.2.175 port 22 (tcp) failed: Connection refused
I know the packet is reaching the router at 10.42.1.1 because inside it I get

^C
8 packets captured
8 packets received by filter
0 packets dropped by kernel
10 packets dropped by interface
Also, inside the router I get
# ping 10.42.2.175
PING 10.42.2.175 (10.42.2.175) 56(84) bytes of data.
64 bytes from 10.42.2.175: icmp_seq=1 ttl=64 time=0.188 ms

rtt min/avg/max/mdev = 0.188/0.227/0.274/0.035 ms
So I know the router can access LAN2.
Also I have
# iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
and
# nft list ruleset
~snip~
table ip nm-shared-enp1s0 {
chain nat_postrouting {
type nat hook postrouting priority srcnat; policy accept;
ip saddr 10.42.1.0/24 ip daddr != 10.42.1.0/24 masquerade
}
chain filter_forward {
type filter hook forward priority filter; policy accept;
ip daddr 10.42.1.0/24 oifname "enp1s0" ct state { established, related } accept
ip saddr 10.42.1.0/24 iifname "enp1s0" accept
iifname "enp1s0" oifname "enp1s0" accept
iifname "enp1s0" reject
oifname "enp1s0" reject
}
}
table ip nm-shared-enp1s0.2 {
chain nat_postrouting {
type nat hook postrouting priority srcnat; policy accept;
ip saddr 10.42.2.0/24 ip daddr != 10.42.2.0/24 masquerade
}
chain filter_forward {
type filter hook forward priority filter; policy accept;
ip daddr 10.42.2.0/24 oifname "enp1s0.2" ct state { established, related } accept
ip saddr 10.42.2.0/24 iifname "enp1s0.2" accept
iifname "enp1s0.2" oifname "enp1s0.2" accept
iifname "enp1s0.2" reject
oifname "enp1s0.2" reject
}
}
which leads me to believe that nftables is doing NAT instead of iptables, but I don't understand nftables yet to know if the above is where the problem lies.
Note: I do have
# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
I believe it is set automatically as a requirement by Network Manager when creating a connection with type ipv4.method shared.
I'm also using UFW and have
To Action From
-- ------ ----
Anywhere ALLOW FWD 10.42.1.0/24 on enp1s0
Anywhere on enp2s0 ALLOW FWD 10.42.2.0/24 on enp1s0.2
which results in
Chain ufw-user-forward (1 references)
pkts bytes target prot opt in out source destination
19230 1466056 ACCEPT all -- enp1s0 * 10.42.1.0/24 0.0.0.0/0
2353 213722 ACCEPT all -- enp1s0.2 enp2s0 10.42.2.0/24 0.0.0.0/0
which leads me to think that a client in 10.42.1.0/24 should be able to reach 10.42.2.0/24 (but not the other way around, which is my goal).
Note: My goal is to use the high level tools Network Manager and UFW ONLY and not mess with iptables or nftables at all. Right now, I'm not sure if I've misconfigured something with Network Manager or UFW, OR if Network Manager and/or UFW have some bug in their design. So, any references to iptables or nftables I've made is purely observing the result of Network Manager and UFW and not some custom iptables or nftables changes I've made.
Note 2: If you look at my network interface names, you my deduce that LAN1 is an untagged VLAN and LAN2 is a tagged VLAN on the same physical ethernet interface. I don't think this has anything to do with my problem as the VLAN stuff is all working totally fine if the router tries to access LAN1 or LAN2. Also, LAN1 and LAN2 can both access the router and the internet no problem. Also, if the VLAN is the cause of the problem, I feel like the Linux VLAN implementation is severely broken because I don't see why it should be able to affect things at the IP level.
How can I further determine if this is a NAT issue or a firewall issue?
UPDATE:
I've done some more testing. I created a new test router and test networks and did not use VLANS and UFW was disabled. I got the same result.
Upon further hacking, I discovered that if I temporarily manually delete oifname "enp1s0" reject and oifname "enp1s0.2" reject shown above, the problem is fixed.
So, it seems like Network Manager is doing some firewalling. Not sure that I like this because Network Manager is not doing any other firewalling, so why do just a little bit?
Also, understanding the rules a bit more (and testing with tcpdump), it looks like it is doing NAT to my local networks, which isn't necessary and maybe isn't preferred (but this seems to be another issue).
So, my question now comes to two options:
reject rules, orreject rules in the first place, on my custom local setup and/or through a bug report somewhere for everyone (I don't know where to report it)?So I installed wine64 and wine32 sudo apt install --install-recommends wine64 wine32 and I’m not sure where it go from there I did some googling and got to this wine ~/Downloads/Creality_Slicer-X.X.X.exe but changed it to the name of the download file after I downloaded it from Firefox it was the windows version. Crealityprint_6.1.2.2458_Release.exe is it case sensitive or am I missing some setup for wine. Please excuse the code not being copy able I left for work and later used my iPhone to ask this.
I have 3 TP Link Wifi extenders (2 different models) and can not connect to any of them in Automatic mode in Ubuntu 24.04. Connecting directly to my hub works OK. Manual configuration of IP addresses to extender connections works OK, so it looks like a DHCP problem. I have tried all the variations to NetworkManager.conf recommended elsewhere.
if I try:
nmcli device wifi connect <SSID> password <PASSWORD>
I get:
Error: Connection activation failed: IP configuration could not be reserved (no available address, timeout, etc.).
I notice that there are other similar questions related to DLink extenders, so it looks like Ubuntu has a problem getting an IP address from DHCP via an extender.
Windows 10 connects with no such problems.
This is a problem with an upgrade to 24.04, and two fresh installs on different machines.
I'm on Ubuntu 22.04 and looking for a way to live cast / stream / mirror my desktop (only Firefox tabs actually) to my LG TV (WebOS v5.30) over LAN.
Note (in case it's useful to give you more ideas to help me): besides the smart TV itself, I also own a Fire Stick 4K and it's connected to it! I also have Kodi on it.
This is what I've already tried with no success:
udp://[my_PC_IP]:[port] in the VLC Fire Stick app nothing happenedCould you please help me in finding other working methods to try (or provide some tested and working instructions for any of the methods above that I've already tried)?
Thanks
I am attempting to install Ubuntu v23.04 over Windows 7 on an old Sony VAIO. I have an 8GB USB flash drive that I am using to do this. The VAIO is not showing the USB in Boot Manager. I have installed the ISO file onto the USB twice with BalenaEtcher and once with Rufus, have enabled booting from external devices in the BIOS, and have set external devices as the highest priority in the boot sequence. There is no option to enable the legacy boot mode. The VAIO's model number is VGN-SR510G
I installed the WSL Bash on Windows 10 so it can act as my terminal in VScode, but the default directory is ~/home/USERNAME
I would like it to be /mnt/c/Users/USERNAME (so on my windows domain side)
I've looked at so many different angles on how to change the default from adding a command to .bashrc that manually changes the directory on startup, to going to the registry editor and trying to change the default directory for CMD, (turns out even that's a challenge as the file I needed to alter doesn't even exist but that's a problem for another day)
Any ideas on how I can change the WSL ubuntu18.04 terminal so that the default directory on startup is different?
i have a ubuntu server system on a dell hardware with two logical LVM2 volumes. One is the boot system an the other is the data storage exist out of two physicall drives which are organized as a RAID1. After boot the data storage is not automatically mounted.

I have a strange situation here. If anyone can help, please do so.
We're talking about a Linux Box running as Router using Ubuntu 18.04.3 LTS, with 2 interfaces: "lan" - which connects to my internal LAN and "wan" - which connects to my ISP.
However, my ISP requires PPPoE connection, so, basically, the "wan" interface is used only a starter for the ppp0 interface.
My problem is that I cannot get IPv6 global address on this server.
I am able to successfully connect to my ISP. I already followed the tutorial from here: http://gruffi.be/mediawiki/index.php/Ipv6_with_PPPoE_on_Ubuntu , but it doesn't work for me.
So, here is what I did:
/etc/ppp/options:
+ipv6 ipv6cp-use-ipaddr
/etc/sysctl.conf:
net.ipv6.conf.all.forwarding=1
net.ipv6.conf.ppp0.accept_ra=2
/etc/wide-dhcpv6/dhcp6c.conf:
interface ppp0 {
send ia-pd 2;
send ia-na 1;
};
# Use subnets from the prefix with id 0
id-assoc pd 2 {
prefix-interface lan {
# Assign subnet 1 to eth0
sla-len 8; # <----- BELANGRIJK: 8 omdat ons klein net 64 en ons groot 56 is en dat het verschil is
sla-id 2;
};
};
id-assoc na 1 { };
/etc/radvd.conf:
interface lan
{
AdvSendAdvert on;
prefix ::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
RDNSS 2001:4860:4860::8888 2001:4860:4860::8844
{
# AdvRDNSSLifetime 3600;
};
};
My ISP told me that it doesn't use Router Advertisement, however it uses DHCPv6 Prefix Delegation and offers /64 subnets.
The problem is that I tried more configs from the net, non of them worked for me.
When I "ifconfig ppp0", it says:
inet 1.2.3.4 ...
inet6 fe80::xxxx:yyyy
No sign of a global IPv6 address.
If I turn on debugging on wide DHCP client and I examine /var/log/syslog, I see that it tries to send Solicit messages to ff02::1:2%ppp0 and the timers reset. I get no reply.
However, router advertisements are working, both on "ppp0" and on my internal lan, because I have a Default Route: "default via fe80::1" when I "ip -6 r". However, no global IPv6 address.
I suspect it something to do with DHCP. The address is not obtained correcly.
I can ping:
ping6 fe80::1%ppp0
64 bytes from...
But when trying to "ping6 google.com", it says: "Beyond scope of source address"
I need to do 2 things, in the long run:
Try to get a global IPv6 address on "ppp0" so my websites can be accesible from IPv6 addresses (DNS already taken care of)
I need to forward whatever /64 prefix my ISP gives me, let's say: "2001:abcd:dead:beef::/64" to my internal computers, but using a fixed part for the internal computers.[/COLOR]
For example:
Computer 1: 2001:abcd:dead:beef::1/64
Computer 2: 2001:abcd:dead:beef::2/64
Computer 3: 2001:abcd:dead:beef::3/64
I do NOT want EUI-64 addresses, NOR do I want Private Addresses. I want my computers assigned an ORDERly IPv6 address with the prefix given, regardless of the dynamic prefix.
For example, after reboot, I might get "2001:1234:beef:dead::/64". I want the same Host-part allocation using "::1", "::2", and so on...
Thank you !
HP Spectre x360 laptops have a hinge screen that can turn 360 degrees. It can be folded to imitate a tablet, for example. When you do fold it, Ubuntu enters its tablet mode -- keyboard and touch-pad will be disabled.
I want to stop that. I'd like to keep keyboard and touch-pad on so that I could connect to an external display and still be able to use them. I've done some googling and found a few solutions:
On Windows, you can do this by disabling the Inter(R) Integrated Sensor Solution driver. I have Windows installed parallel to Ubuntu, so I tried doing that. It helped solve the problem while I'm in Windows, however, when I go back to Ubuntu, the problem remains.
On Ubuntu, people generally recommend using the xinput command to control input devices (e.g. inable/disable them). But it doesn't seem to reflect the real state of affairs... For example, right now I'm typing this using an external keyboard and mouse; embedded keyboard and touch-pad are de-facto disabled -- I cannot use them -- as the screen is folded and tablet mode active. Yet, if I run xinput and check the props of my touch-pad, it reports it as being enabled.
Here are some snippets from of xinput betraying me... :)
As you can see on the second snippet it says Device Enabled (154): 1 which is a plain lie. Trying to run xinput --enable 18 anyways gives nothing -- touch-pad stays disabled.

Another program, acpi_listen seems to catch that moment of folding the screen. It prints video/tabletmode TBLT 0000008A 00000000 every time I do that. Although I am not sure as to how to use that to resolve the issue.
It seems like the problem is deeper, at the hardware level, but I'm not an expert yet, so I'm asking for help. How can I prevent keyboard and touch-pad from being disabled?

I'm trying my hand at getting my laptop to run Ubuntu.
My laptop is a Toshiba Satellite L755-S5153. It came preloaded with Windows 7. I upgraded the laptop to Windows 10.
I downloaded the Ubuntu 16.04.3 disk image (ISO) file to the laptop's hard drive.
UNetbootin was downloaded and run. The type was set to hard disk and Diskimage was set to where the ISO file was downloaded. I pressed OK, and UNetbootin proceeded without any problem.
When I try to boot from UNetbootin, I get a black screen with the this error:

I have A laptop with Ubuntu 17.04 & installed Gthumb, I need to sync my phone and remove the photos because I'm running low on space, but the PC isn't recognizing there are pictures.
Is there a specific way to do this? I'm open to any other software suggestions as well.
I'm using Ubuntu 17.04
I'm completely new to Linux and just installed Ubuntu 16.04 LTS with Windows 10. (I've installed Ubuntu on a different partition than Windows, if that would be of any help). So I set up Ubuntu but my Ethernet is not being detected and connected. The same works fine when on Windows. I've searched other questions on this site but none of them solved my problem. I would be glad if someone helped me out here! Thanks!
Okay, so I am the user who put a bounty on the question. I was unable to comment due to lack of reputation. But now I think I should take the reins of this question into my hands. So, I will describe my system's properties.
I had installed Ubuntu 16.04 on a separate partition in parallel to Windows 10. The laptop is Lenovo Z51-70. The problem is that the ethernet is not connecting on Ubuntu.
This is the result of "ipconfig" on Windows.

Also, I would like to add that rebooting didn't help. Restarting network-manager didn't help. Giving up IP on Windows before booting into Ubuntu didn't help.
The output of the script which @DavidFoerster mentioned is at wireless-info.txt.
I have deployed my codeigniter folder into /var/www/html . But when i am trying to access it using http://localhost/CodeIgniter/ this is showing Server error

The website encountered an error while retrieving http://localhost/CodeIgniter/. It may be down for maintenance or configured incorrectly. But when i am creting a new folder into /var/www/html/ and creating a hello.php file in it and that is working fine.
I am posting this question with the reply because I already find the answer after some searches and I think it could benefit other people since I didn't find easy to solve this on Ubuntu 15.

How to I configure this setup in Ubuntu 15 server?
Every time I try to install the Nvidia drivers for my graphics card, the GTX 760, I end up with a black screen on boot which stops me from using the computer.
This happens regardless of where I download it from, it seems, as I've tried both with the Nvidia website, apt-get and Ubuntu Software Center. I've tried nvidia-current (349) as well as 319, with the same result from both.
I actually sat down and read Nvidia's readme as well, which simply doesn't help.
How do I install drivers that work? Could I be missing a step?
EDIT: Apparently it's not my graphics drivers that are messing with my - it's my screen. I have one of those cheap 27" 2560x1440 monitors, a QNIX QX2710, and this monitor does not report it's EDID correctly. I tried following a couple of guides but with no progress. I'll put this on hold, it's simply not worth the time and frustration.
I have two 27" monitors with a 2560 x 1920 resolution each. When I try to extend my desktop across them both I get the below error:
So, if I need to increase the maximum virtual screen size? To include a resolution of 5120 x 1920.
I've been trying to do this for about 12 hours now....
I have tried using xrandr arandr and a bunch of other tools recommend on this site and other forums.
I have added a xorg.conf file to /etc/X11 (which didn't exist already, and I generated) which now looks like this:

I also tried a bunch of other similar answers, and in the process messed up the xorg server and wasn't able to boot at all until re installing it.
I know xserver changed a bit from 12 to 14, and now uses a bunch of files in /usr/share/xorg.conf.d, which I have also played around with. My understanding is putting a xorg.conf file in the /etc/X11 folder would overrule that anyway (but really, I've been trying anything).
So far nothing has worked.
Some things have had an effect, like me not being able to boot up at all, or get past the logo, which have been solved by root terminalling in safe mode to undo changes or reinstall xserver.
Any ideas would be appreciated.
