My Canon MF4350d multifunction printer no longer prints. It is reconginzed via USB and it worked, but not any more after upgrade to 25.10
I've been running an Intel NUC11PAHi5 Mini PC on my local wired ethernet. I assume this has an Intel ethernet adapter. I am on Ubuntu 24.04.3 w/ kernel 6.17.0-14-generic. Recently I noticed the wired ethernet no longer appears in the Ubuntu 24.04.3 Settings. I noticed this at some time after what appeared to be a very nearby lightning strike. So I suspect a hardware issue. I'd like to ask for ideas as to further steps I should take to diagnose this issue and determine whether it is fixable. I have pretty rudimentary linux skills, but so far I've tried "lshw | grep -i ethernet" and "ip link". These show my wireless adapter, but my wired ethernet is nowhere to be seen.
thanks
I can't remember if I've already asked this here, so I apologize if I have.
I did an update this past Sunday, and it turns out that I have no WiFi. I can get Ethernet, but no WiFi connection. I'm able to get to the GRUB screen and choose between kernel 6.17.0-14 and 6.14.0-37, but the newer kernel has no WiFi connection. I've been to several places and have read numerous solutions, but nothing seems to work. I can connect to my WiFi with an Ethernet cable and that works, but there's no WiFi, even though I had it working fine in earlier versions.
To make things worse, somehow kernel 6.14, which had WiFi and which I could switch to with grub also has lost WiFi connectivity. I don't know what else to do, or where I should go to look for information.
Is there any way I can 'reset' things in the older version, etc.? I apologize if it's a stupid question, but I don't know exactly what to say. I'm familiar with the terminal and the command line, but I'm not that well versed in Linux commands, etc.
I've been on other websites, and this is the information I have about my WiFi so far:

Can I go back to some older kernel, etc.? What do you think would be the best thing for me to do?
Desktop environment was recently changed from unity to plasma kde. Initially both environments worked fine. A few days later while attempting to revert to ubuntu environment, the login screen only presented me with The computer owner's name instead of the user name. Since the computer's owner name is not the login name I am locked out of the system. It will not accept logon attempts even when I supply the actual login name. I cannot change the Desktop manager. All attempts to get the system to offer the actual login name have failed. What does one do. Why does the system present the computer owner's name when it is two names, both capitalized and separated by a space? This is a dautting situation for a novice?
I'm selling my 1TB hard drive to a friend who's a data recovery geek. This drive contains a lot of my personal data, which I rightly don't want to give to him. Then I used shred to clean the entire disk. This is the command I used:
root@cellar:~# shred -z -v /dev/sdc
It took him many hours, making 4 passes, including the final one of zeros.
However, I read online that shred can have problems with some filesystems, making its work ineffective, thus not completely removing the data from the drive.
I also read that a lot depends on how the filesystem is mounted, whether journal or ordered. So I thought I'd post the fstab snippet where it talks about the drive:
# /srv was on /dev/sda1 during curtin installation
/dev/disk/by-uuid/d97db283-0f7b-4c34-84bd-68c28cb3a65e /srv ext4 defaults 0 1
And now I ask you: have I done a safe data wiping or do I need something else?
Thanks
Can someone provide me a link to a page that explains how to properly format a post in this forum. Or is there a video example etc.. Thank you.
I have no sound on my active stereo speaker connected via SPDIF to this motherboard.

Then I found out:

This finally makes sound.
I know I can do:
pactl load-module module-alsa-sink device=hw:1,2
Then select this newly created device as fallback (default) device.
But do I have some more elegant way to do this? Maybe without load-module?
I'm looking for a solution for Ubuntu 22.04 CVE-2025-37899 remediation as a new kernel is not available.
Kernel version: 6.8.0-1044-azure
VERSION="22.04.5 LTS (Jammy Jellyfish)"
I am on Ubuntu 22.04. In trying to get my laptop to suspend, I have both clicked "Suspend" from the GUI and executed sudo systemctl suspend from the command line. In both cases, the screen goes black—but not the kind of black that's a fully turned off display—for 10-20 seconds and then it comes back on. In neither case is any input being sent to the computer via keyboard or mouse. What is causing this and how do I fix it?
Update #1: I think I did something to disable suspension in the past due to the USB drive from which I'm running Ubuntu always being disconnected after waking up. But, I already unmasked suspend.target, so I don't know what else I'd need to do.
Update #2: Here is the output from dmesg after attempting sudo systemctl suspend:

Why does installing programs with the terminal seem excessively slow and often fails? For example, I tried to install Inkscape using the sudo apt install inkscape terminal command, then lower down on the page I confirm by typing Y
Then it dragged out for 10-15 minutes and eventually failed with a repeating error message line that would not stop, and I had to close the window to stop it.
Warning: Tried to start delayed item https://mirror.lc/ubuntu questing/universe amd64 fig2dev amd64 1:3.2.9a-4, but failed
Then I installed the program again using the App Center, and it worked fine and finished in 5 minutes.
What is the preferred method to install programs? Now I am trying to install the Gnome Panel using the terminal and getting sort of the same thing: ##% [Waiting for headers] (I'm not sure if it will fail or not, and it is taking an extremely long time.), but I did not find Gnome Panel in the App Center.
Furthermore, I have been trying to learn how to create a desktop link to commonly used websites. Even though I have read the help menus it doesn't work. I don't understand how something that should be so common and simple is so overly complicated.
I'm using Ubuntu Studio 24.04 LTS (Long Time Support ...)
Since I had problems with the Dolphin filemanager on my NAS drives, I've tried to find a solution. I've got all my media files on NAS (video, audio, photos). To work with it, it is required, to have the media data in columns of the filemanagers details window to be able, to compare it quickly. But this depends from baloo, which is incompatible to network storage (changing inodes and device IDs after each reboot ...).
Posting this at https://bugs.kde.org/show_bug.cgi?id=515574, I had to learn, that Ubuntu 24.04 LTS uses a rather outdated version of Dolphin:
Hi, I'm afraid Dolphin 23.08.5 no longer receives updates or maintenance from KDE; active versions are 25.08.3 or newer. Please upgrade to an active version as soon as your distribution makes it available to you, or use other application distribution methods such as Flathub. Dolphin is a fast-moving project, and bugs in one version are often fixed in the next one.
If you need support for Dolphin 23.08.5, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.
The official repositories are containing no newer versions than 23.08.5.
Actual is 25.12.2
How can I update?
As an alternative, I've tried to install nemo (Cinnamon filemanager). It works well, but the nemo-media-columns are missing for ubuntu noble. Installing it manually does not work and let nemo crashing.
Ubuntu install on Dell Inspiron 15 7586 fails with no Bootable drive found.
I am able to successfully boot from bootable Ubuntu USB, delete all the paritions, an install Ubuntu as default with Standard installation (it is connected via ethernet cable for internet access). At the end, setup requests removing installation media and press <ENTER> to reboot. I press enter, remove USB when laptop powers off. When it boots, Dell BIOS begins a memory check; then boot fails.
I have followed Dell suggestion to prepare BIOS for Ubuntu Linux.
This is not a dual-boot system. I have successfuly installed Ubuntu as a VM to verify I am not missing something. Apparently, I am. Any suggestions?
Having issues connecting with ASPERA to NCBI SRA; connection is "timing out". Tried the test connection page that IBM set-up and got the following error. Any suggestions? (Using FF).

Last night my Dell 7590 on Ubuntu 24.04.3 LTS ran fine. This morning there was no network except lo and I didn’t do any updates.
ifconfig only shows lo running, but no other interfaces hard or WiFi. It’s hard to include much here because it can’t connect, so I can either add photos or hand type.

I was able to get some information off of the computer to a USB and I'm uploading it here.
What drew my attention to this is that something went wrong with nvidia at the same time and without the network I couldn't solve it. It does appear that some quiet upgrade occurred. I just tried sudo apt autoremove, and here is the relevant error I see there. I wonder if they have a common root cause.

When I installed them it said the gcc version used for v4l was different than what was installed. It was built with gcc 15.2 and I have 13 something. It looks like getting that installed is not easy. I'm really puzzled how this went so wrong. There must be a lot of people out there with similar problems.

We have been developing an architecture where the system disk has four partitions, two boot partitions and two root partitions. This allows a system running in boot1/root1 to self-install a brand new operating system on boot2/root2 and reboot on it (and vice-versa). We successfully implemented this strategy on the Intel/AMD and ARM64 RPI architectures and it has been working very well until now. With Ubuntu 25.10, the kernel can't boot anymore, as it seems unable to locate the root partition.
See the below error message.

In the above partitions layout, it is normal that ROOT2 is absent, as our initial disk contains only one ROOT1 partition, the second ROOT2 partition being created on the fly on the first boot.
So I've read the comprehensive Broadcom installation article. I ran lspci -nn -d 14e4:
which gave me:

After upgrading the Linux kernel on Ubuntu (via sudo apt upgrade) to a newer version (in my case 6.17.0-14-generic), Wi-Fi stopped working. The laptop uses an Intel Wi-Fi 6E AX211 adapter with the iwlwifi driver. The device was detected by PCI tools, but the Wi-Fi interface was not usable and the device showed as UNCLAIMED in lshw.

As as developer of a Linux video cutting software I used Virtualbox the last 20 years for different distros. Until last month that software could be tested on any of my vdi images. Today (as of 23/12/2025) the app does not seem to work on 25.10 - testing it on a "native" installation of Ubuntu 25.10 there was no problem.
I wonder if the 3D acceleration is currently broken for Wayland in VirtualBox and if someone knows a "tweak" to fix this, except not using that software and going for KVM/QEMU (my host is Linux as well).
My software currently works on Linux Mint, Ubuntu 24.04 (Wayland), Fedora, Elementary and Arch Linux. In Virtualbox I use VBOXSVGA and 3d enabled.
The VM for Ubuntu 25.10 was configured for VBOXSVGA, VBOXVGA and VMSVGA, but none of these have worked.
Update for clarification
The problem is that 3D acceleration does not seem to work with my Ubuntu 25.10 guest. Other guest distros do not have that problem, hence my question in this forum.
The installed Virtualbox is up to date, with the latest GuestAdditions on its hosts activated.
I'd appreciate any ideas that could help me to run and test my software on VirtualBox or a reason why I should abandon this platform.
This issue started when I upgraded to Ubuntu version 22. I've followed various methods and solutions given on this platform, including adjusting the BIOS settings, but the issue persists. Furthermore, it alerts;
After some boot messages have appeared, the process stops at this point:

Additional Informations:
Dolphin shows:
A view to the information panel on the right side shows the correct data. So the information is available for dolphin.
Just to clarify the question, wether indexing has to be enabled, or not:
With indexing enabled (including content):
On my system, Dolphin does NOT show Width and Duration in its columns, but still in the preview. The display according to the first picture above has not been changed.
The pictures show also, that the path for the displayed movies and images are within the indexed path.
There must be some other settings or configurations, to get it working, but out-of-the-box it does not work on Ubundu Studio 22.04 LTS.
I'm trying to run immersed executable and I get the following errors:
Immersed: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by Immersed)
Immersed: /lib/x86_64-linux-gnu/libpthread.so.0: version `GLIBC_2.30' not found (required by Immersed)
Is there a way to upgrade GLIBC or does I have to upgrade Ubuntu to do that? I'm running Ubuntu 18.04.6 LTS
When I open the same websites in Firefox, Chrome, and Vivaldi, the content appears much smaller in Firefox than in both Chromium based browsers, despite site zoom is set to 100% in all of them.
Using content with annotated pixel sizes, taking screenshots, and measuring them in GIMP makes me conclude, that the display size is correct in Chrome but too small in Firefox.
I found an old Mozilla support issue. While it's about content being to large on Windows, it says that Firefox is supposed to respect system-wide device pixel density settings by default, and that it can be overridden setting layout.css.devPixelsPerPx to a custom value in about:config. While a value of 1.2 seems to "fix" the problem, I would rather fix the root cause and make sure my system is set up correctly.
Where would I adjust Linux device pixel density settings to correct the zoom in Firefox without breaking it in Chrome?
I use Ubuntu 20.04.3 LTS with Ubuntu Budgie desktop on a Tuxedo Infinitybook.
I switched to Ubuntu, recently. I usually work with a printer that does not have support for automativ duplex (Canon MP495). I know the printer is old, but it works. I installed gnome-manual-duplex package manually as it is not supported in the latest versions. It does not work at all. What should I do?
Installed Tomcat by following this link. Installed the latest Apache NetBeans from Ubuntu Software center, version 12.1. The installation of tomcat completes without any issues and I am able to access the Host manager and application manager. When I try to add TomCat server in NetBeans IDE the error "The specified Server Location (Catalina Home) folder is not valid ". I tried all the other solutions but nothing works for me. Anyone who has experience in setting this up on an ubuntu machine may be of help in this case.
If any further info is needed please mention them and I will provide it here.
I installed Ubuntu 18.04 on my Mac mini (late2014) and when it boots, it goes directly into Ubuntu. However, it won't load. An error message states the following:
failed to open \EFI\ubuntu\grubx64.efi - not found
failed to load image \EFI\ubuntu\grubx64.efi: not found
start_image() returned Not Found
I know for a fact that I haven't overwritten my partition of the Mac OS (I was very careful about this and double checked everything) but I didn't load rEFind in the Mac OS side before doing this. I have tried using the Apple commands such as option, command+r, and command+option+O+F to bring up the UEFI or other menus with no success and I keep getting returned to the screen error above. I have tried an Ubuntu live boot on USB and booting with a bootable USB containing rEFind iso and still get returned to this error screen.
I do not have a keyboard that has a USB connection port (all my stuff is Bluetooth) and I will try this tomorrow because I found somewhere that the new Mac minis don't load the Bluetooth keyboards until the kernel is loaded which may explain why I can't open the UEFI.
what I am looking for is any additional help that might solve the problem. I currently can't get into either OS or reinstall either of them. I really would like to get into using Linux, but I don't want to give up my Mac OS either. Please help!
Thanks.
What are some different ways to view what groups a user is in?
I've spent a couple of days on this and am at my wit's end as to how to move forward.
I have an ASUS Zenbook UX303UB with Windows 10 and Ubuntu 16.04 Dual boot. It has an NVIDIA GeForce 940M dedicated GPU with 2GB memory. I use Ubuntu primarily for programming. I want to play around with some deep learning tools like tensorflow and theano, for which I first need CUDA to work. Only CUDA 8.0rc appears to work with Ubuntu 16.04 officially.
First, I went to the NVIDIA website and downloaded the CUDA 8.0 runfile. I followed their instructions to install and did so in TTY1, including blacklisting noveau and adding
export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
to the end of the .bashrc file.
When I try the test example that NVIDIA provides,
$ cd NVIDIA_CUDA-8.0_Samples/5_Simulations/nbody
$ make
my output is:

In the diagnosis process, I realized 2 things:
1) nvidia-smi doesn't seem to work (nvidia-smi: command not found)
2) When I do cat /proc/driver/nvidia/version I get cat: /proc/driver/nvidia/version: No such file or directory
I then decided perhaps there is some trouble with the NVIDIA driver. So I followed the instructions on Issues with Nvidia graphics driver and CUDA after apt-get upgrade
Basically, to purge all nvidia drivers, turn off lightdm and enter runlevel3, and install the NVIDIA driver runfile from NVIDIA's website.
However, there is an installation error and it aborts.
I then reboot and purge all nvidia drivers and do a sudo apt-get install nvidia-367
I'm back to square one now. Additional diagnostic information as follows:

What changes should be made to make haproxy as a daemon service?
I was formatting my drive and found a partition system named cleared and unformatted. What are those partitions and why they are in GParted app ?
I'm attempting to set up a VPN from my Android phone to my home computer using pptpd on Ubuntu 12.10. I have so far done the following.
Setup a virtual NIC like this...
cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto eth0:0
iface eth0:0 inet static
address 192.168.0.1
netmask 255.255.255.0
and then configured pptpd like this... (commented line has been omitted to save space)
cat /etc/pptpd.conf
option /etc/ppp/pptpd-options
debug
logwtmp
localip 192.168.0.1
remoteip 192.168.0.100-200
/etc/ppp/pptpd-options
name pptpd
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
proxyarp
nodefaultroute
debug
lock
nobsdcomp
/etc/ppp/chap-secrets

But all I get from syslog even with debug turned on is..
Apr 8 14:53:25 Ellit pptpd[19488]: MGR: connections limit (100) reached, extra IP addresses ignored
Apr 8 14:53:25 Ellit pptpd[19489]: MGR: Manager process started
Apr 8 14:53:25 Ellit pptpd[19489]: MGR: Maximum of 100 connections available
and when I finaly try to connect with my phone all it says is...
Apr 8 14:29:43 Ellit pptpd[25180]: MGR: dropped small initial connection
I don't realy know where to go from here... have I made and error in thinking that a virtual NIC will work and why can't I get any debug information even when I asked for it in the configurations?
EDIT: The last line when I try to connect seems to appear somewhat random, I can right now not reproduce it but I fairly sure it related to my connection attempt before and I have not changed anything from then. I'm starting to suspect that my Android ISP is blocking VPN but that would be... insane.
