I'm having a weird problem trying unsuccessfully to update the kernel to 6.8.0-100 on a 24.04 computer. It's throwing apt errors (held back and/or no installation candidate).

The host popped up this morning as requiring a kernel update from 6.8.0-94 to 6.8.0-100. I have some scripting in place that would normally handle this, but today things are not going my way.

I'm trying to decide if this is:

• repo lag? - but I've tried various regional repositories with the same outcome

• 6.8.0-100 has been pulled?

• Something I've never encountered before

EDIT: "aptitude -f install" and "apt install -f" also refused to install the new kernel. "apt install -f" declared 6.8.0-100 "REMOVED" despite not being installed, and no longer appears as an upgrade option after "apt -y update".

Dell management has referred this issue to Ubuntu for guidance regarding Ubuntu 22.04 on their server.

Their response was as follows: “Ubuntu Server 24.04 U3 is supported on the R7725, as this is the latest 17th-generation server. However, you may wish to check with Ubuntu support for any further assistance.”

Could you please share Ubuntu management’s perspective on this case? Specifically, is there a need for Ubuntu to provide guidance or coordinate with Dell to ensure proper support for this configuration?

Thank you for your time and assistance.

I decided to snag my dad's old computer tower, and of course like a goofy goober he is running Linux and was met with a password. I got into contact with him and he said it needed to be rooted, so I went to Google which was very unreliable because it kept asking for a Recovery mode which I can't find. Going into the Advanced settings all I see is the generic kernels. There's nothing with (recovery mode).

I have a fresh install of Wine on Debian 13 (Xfce4) and am trying to adjust the UI scale because I have a high DPI screen. When trying to set DPI in winecfg > Graphics > Screen resolution and applying, these settings produce the following (4 is max DPI of 480):

Is it supposed to be like this, am I missing something? Is this a bug? How can I scale the text and controls in other ways?

I wouldn't post here if I didn't feel like I'm struggling with something basic that I'm missing.

I recently installed a new Ubuntu installation. It was originally installed as Ubuntu-server, due to the desire to install in RAID, and then Ubuntu-desktop immediately installed via apt.

It has booted fine, but I've had problems with the hardware crashing. I got rid of an NVIDIA card and crashed went from daily to less than weekly, so I guess that's an improvement.

The problem is that I can't boot the system, but it looks like everything is going fine. It is booting without the splash screen, and everything has a green [OK] but then, it just stops. This is before networking is working, no GUI and no terminals running on tty2,3,4,5. I can switch to those ttys, but there is just a blinking cursor. Without networking, of course, no SSH.

If I boot into recovery mode, networking works right away, and if I "continue boot" it goes into the desktop, and networking, ssh, etc. are working, but only at 1024x768 resolution and SSH won't connect to a terminal because it isn't "fully booted" and kicks me off.

I've run fsck on all of the filesystems and, although the array that gets mounted as /home has some issues with tree dpeth or something, they didn't seem like hard errors and correcting them didn't fix it.

For reference, this is where I end up:

System responds to ctrl-alt-del and reboots cleanly, as well as REISUB reboot, it just won't load the environment completely - seems like it thinks it's done.

Logs don't seem to contain any issues. I've disabled the wait for network servic, for now, since that seemed to be hanging, if that is a clue. Where should I be looking???

I got on 24.10 these problems

I have just upgraded from Ubuntu 22.04 to 24.04 and I'm regretting it.

The file manager nautilus has become horrible, the icons are massive, the lines spaced out, it's a scroll fest. It was fine in 22.04. There was a button on the tool bar that allowed me to create a new folder or open a new tab. That button is gone. There is no straightforward way to create a new folder now.

This is not the first time that nautilus has been downgraded. In earlier versions, nautilus remembered the folder I had selected. But after one of the upgrades that functionality went and every time I return to nautilus I have to start finding the folder from scratch.

Why do software engineers do that, why do they create upgrades that are in reality downgrades?

My personal computer has an integrated GPU (a Radeon Vega 3 Graphics), from which my first monitor is connected through a VGA cable, and a dedicated GPU (an NVIDIA GTX 750 Ti), from which my second monitor is connected through a DVI-I cable. It is running a dual-boot Ubuntu 25.10/Windows 11 set-up. On Ubuntu, I've selected the nvidia-driver-580 additional driver for the dedicated GPU.

While on Windows this dual-monitor setup works fine, on Ubuntu the second monitor isn't being recognised by the system, and I'm unable to use the two monitors together.

When the additional driver for the dedicated GPU is changed to Nouveau in Software & Updates > Additional Drivers, the two monitors work together well, but, as I regularly play Steam games on Ubuntu, I wish to continue using the better-performing NVIDIA drivers, as I did when I only had one monitor and used it plugged to the dedicated GPU.

Being on Ubuntu 25.10, I'm on GNOME 49 and thus using Wayland. GNOME 49 is incompatible with X11 and makes using xrandr ineffective.

How can this issue be solved?

My laptop is running in a kernel 6.14.0-37-generic.

And since then, it didn't get any updates. Now I don't know what is the procedure.

My battery was very low (which was understandable). Plugging the power failed to charge the laptop consistently.

I suspected a bad contact, and maybe a hardware failure, but the behavior of the Battery Level app seems inconsistent or at least unclear to me.

Here is a log of recent values:

Power mode: -> Power Saver
10:37 2:20, 60%
10:55 2:19 until fully charged, 65%
11:00 2:27 -, 66%
11:10 2:37 -, 68%
11:29 3:15 -, 71%

I mean that it is charging, isn't it, as the 'level' keeps growing,
but then, why is the time until fully charged grow as well?

• Dell Inc. XPS 13 9380

• Intel Core i7-8565U × 8

• Ubuntu 24.04.3

It stalled at 73%
At times, I've seen 'Charging'
The time until fully charged grew to 275 hours 36 minutes... (at 13:35)
Down to 125, up to 153...

Surprise: it rather abruptly jumped to Fully charged 100%
I'm still unsure about the contact of the power cable...?

After a couple of hours, I found the situation: 4 hours until fully charged 100% and restart required.

So the battery level and the charging speed are completely disconnected. Now should I buy a new laptop, or is this fixable?

I've been able to use in terminal:

sudo kill 4893 (to stop fwupd, using its PID, from running without any issues.

Today I tried recklessly in terminal:

sudo killall fwupd

Now my 'Files' is quirky, crashing, etc. Entire display will freeze, blink off, then back on and seem normal until trying something else then blink on/off...

So I tried in terminal:

sudo systemctl enable fwupd

which ran for a while then had to just do ^C to stop and then typed exit to close terminal.

Tried GRUB recovery but didn't help...

Everything else works fine - just file system access is screwy.

Any advice?

I run nautilus in terminal and get:

$ nautilus

...and it opens the GUI, but it is still freezing/blinking/crashing

Description:
The goal of this PPA is to provide the latest point release of Mesa plus select non-invasive early backports. Deviations from upstream packages are listed on the package details page.

--- Support status ---

Bionic (18.04), Focal (20.04), Jammy (22.04) - Discontinued - Long term users can use kisak-mesa stable
Noble (24.04) - Supported
Plucky (25.04) - Preliminary support (Not tested locally)
Questing (25.10) - Preliminary support (Not tested locally)

Note: Please report any issues to mesa. ARM builds are not tested locally.

--- Is this PPA stable? ---

Short answer: Mostly.

Long answer: Compared to bleeding edge mesa PPAs, there is a much lower chance of complications, but as Ubuntu LTS releases age, the odds of unexpected interactions between older kernels / compilers / X increases with each major release. Anomalies are inevitable the further the host system gets from the configuration active mesa developers use on a daily basis. If you value stability over support, https://launchpad.net/~kisak/+archive/ubuntu/turtle/ is available as an alternative.

In the event that there is a major issue with new mesa on an older Ubuntu LTS and the mesa devs are not interested in triaging the issue, then the Ubuntu LTS release will be dropped from this PPA and the last release pushed to kisak-mesa stable will be frozen.

--- Package status ---

llvm - Following latest point release supported by mesa
mesa - Following latest point release
libdrm - Updating as needed for mesa

--- Removal ---

It's strongly recommended to remove this PPA before upgrading to a newer Ubuntu release or using another mesa PPA.

sudo apt install ppa-purge
sudo ppa-purge ppa:kisak/kisak-mesa

Note: Using ppa-purge with Ubuntu derivatives needs to include -d <based_on_name> to work safely. For example, Linux Mint 20 is based on Ubuntu Focal, so that would make it:

sudo ppa-purge -d focal ppa:kisak/kisak-mesa

--- Donations ---

I can't accept donations and any random donation site account is a scam. If you have some extra money burning a hole in your pocket, please consider sending it to a charity of your choice (for the poors, animals, whatever else you may think it might need it), then send Oibaf a note that I stole the suggestion from his PPA.

$ sudo -c 'rm -rf /root

I've been trying to figure out for days what this problem is. It happened after I updated to Kubuntu 25.10. At first it minced the bootloader somehow, but I fixed that. Now I have another problem.

Safe Boot is off, EFI firmware exists, and the grub menu is correct, but when I try to boot into Kubuntu, I get nothing but a black screen (edit: forgot to mention, when i press power button after waiting forever, the kubuntu logo shows up before power off).

Booting from recovery mode works, though. I don't dual boot, there is no Windows install.

I've tried reinstalling Kubuntu numerous times to no avail.

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p2,
using the following options:  nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 25.10 entry (nvme0n1p1/efi/****/grub****.efi (**** will be updated in the final message) file) !

I'm new to fiddling with Kubuntu, so I might be missing something obvious. I've tried to find info online, but nothing seems to work.

What could be causing this problem?

Maybe I've no audio from my HDMI monitor because the card as alsamixer reports it, has 00 for everything and that everything is S-PDIF?

Someone else solved their "No audio from NVIDIA GPU, alsamixer only showing S/PDIF for HD" by:

disabling intel gpu and replacing noveau with Nvidia prop drivers.

But, my NVIDIA GT 220 is stuck using nouveau.

Also found: 6-year-old archlinux bug fixed by regression?

Maybe also relevant: occasional HDMI loss from my mixer if I wake up monitor from sleep. And speaker-test doesn't produce sound.

DVI-1? Hmm... People are saying "Some DVI-D sources use non-standard extensions to output HDMI signals including audio (e.g. ATI 3000-series and NVIDIA GTX 200-series)."

And well, "NVIDIA GTX 200-series" sure does describe my "NVIDIA GT 220"... Is that the problem???

I have Kubuntu 25.10 on a laptop with Intel internal graphics and an Nvidia 4060 laptop GPU. I installed Nvidia drivers (590-open) and now my boot gets stuck at Begin: Running /scripts/init-premount. When I Ctrl+Alt+F3 I can log in from a tty and run startplasma-wayland and it will load into the GUI and everything works, but if I reboot I get stuck at Begin: Running /scripts/init-premount. I changed the sddm settings to auto-login and I can boot with no issues from a shutdown, but then my computer is not locked with a password. Do you have any ideas?

Replaced Gnome with Enlightenment on 24.04, and got past the boot logo, even though it took a while where the throbber stopped spinning but my cursor was on screen, but this doesn't look anything like a desktop at all, so I shut it down.

Took a video and turned it into a gif with ffmpeg:

journalctl is reporting some red logs, when looking things up, feels like a similar report to this Bug 206225 - nouveau: Screen distortion and lockup on resume, given that I'm seeing well, distortion and the logs are mentioning nouveau, TRAP_MP_EXEC, and INVALID_OPCODE.

Maybe I also deleted the drivers for my NVIDIA GT 220 via apt autoremove?? Because I can't find any nvidia-driver entries in my installed packages. But neither can I install them via apt?

I need some help troubleshooting my system.

I can never suspend my laptop. It's always blocked by some file tasks that completed with no problems:

andy@Inspiron16:~$ gnome-session-inhibit --list
org.gnome.Nautilus: Moving Files (logout, suspend)
/usr/bin/google-chrome-stable: Download in progress (suspend)
org.gnome.Nautilus: Moving files to the Rubbish Bin (logout, suspend)
org.gnome.Nautilus: Moving files to the Rubbish Bin (logout, suspend)

GitKraken also tells me: File watching failed to start for this repository.

I increased the inotify max watches and instances, but it didn't help.
I'm running latest Ubuntu, normal usage and some development, nothing crazy.

I'm doing this:

play -V2 -e signed-integer -b 16 -r 44100 -c 2 -t raw myfile.pcm  

And it says this:

play WARN alsa: can't encode 0-bit Unknown or not applicable  

The file seems to play perfectly OK, but it would be nice to get rid of the warning.

It's not clear (to me at least) what it's complaining about. The -b 16 should have set it to a 16-bit input value, so I don't think I'm telling it to encode a 0-bit sound, and if I was, why would the sound be playing OK?

I can of course just ignore the warning, but I prefer to know what's going on.

I have Ubuntu installed as a dual boot along with Windows 11. I also installed Thunderbird for email. The dates in Thunderbird show as mm.dd.yyyy I would like to see dd.mm.yyyy, which at least to me is more logical.
The date in the desktop clock is Feb 16 12:46.

I have searched high and low for a solution to this without having to type code. Any ideas?

I'm trying to install Ubuntu in a Hyper-V VM on a Dell Latitude 7455, which has a Snapdragon X Elite X1E-80-100. I've found an ARM64 version of Desktop Ubuntu 24.04 and 24.10 on cdimage.ubuntu.com, but could not get past the Try or Install Ubuntu screen.

Every time I attempt it I get a black screen with a cursor that blinks once and then freezes.

I have also attempted to use VirtualBox, but VirtualBox doesn't support ARM64 Windows.

Is it possible to get Ubuntu to work in this environment. If so how? If not, are there alternatives?

When I try to run pnpm start after installed pnpm with this method: npm install -g pnpm, the result giving error:

Look at all these groups! I have no idea what most of them even do. Is there documentation for what each group has access to? A lot of them are self explanatory, and I could google them individually, but I would appreciate an online documentation of the groups created by Ubuntu and what they are for. My search for this has turned up fruitless.

I was trying to install geopsy software, but when I ran sudo make install the following error occured:

before I ran sudo make install, I ran sudo ./configure -prefix /path sudo make -j 2

Please help me fix this problem. I'm new on Ubuntu.

Installed wireguard in Xubuntu (Ubuntu 18.04.4 LTS) via PPA. The kernel module failed.

# modprobe wireguard
modprobe: FATAL: Module wireguard not found in directory /lib/modules/5.3.0-51-generic

I've searched a lot about this issue, but mostly found the poster either did not have kernel headers or they were mismatched. I checked and those on my system were fine.

When I checked

Can you tell me how can I get the missing libraries please?

Thank you Hadeel

I was trying to install Windows 10 from USB, but I get "Windows cannot be installed to this disk due to GPT partition style" error.

I found out that I needed to convert partitions to mbr, but that would erase data so I searched for another solution and I tried some things through commands.

The last commands I tried were:

bootrec /rebuildbcd  
bootrec /fixboot

...and then it died.

When I try to boot up I get this error message, then it restarts itself automatically.

How can I at least get Ubuntu back running?

After selecting ubuntu from the grub screen, it hangs on a solid purple screen and I have to shut down. I have an Asus laptop with an Intel UHD 620 graphics card. I am able to boot in "nomodeset" but the resolution is stuck at 800 x something. Is there any way to get this working without nomodeset?

this question might seem pretty basic and straightforward but I wanted to make I do it properly without data loss.

I have two drives. My primary being windows 8. My secondary is partitioned with one part being Ubuntu and the other partion being room for storing my back up files, important files.

So my question is how do I remove the partition and uninstall Ubuntu from my secondary? I'd also like the space freed up from the process to go back and combine to one partition so I have more storage space for my back up files.

As you can see I gave ubuntu way to much space. C drive is windows 8. E Drive is my storage drive.

I upgraded Kubuntu 14.04-x64 to 14.10. Now flash does not work in Firefox. Now flash is an empty area which sometimes is black when cursor is under it.

But flash still works in Chromium.

I installed a single cluster node on my personal laptop. It has successfully installed and jps is displaying all 5 demons, but when I try to enter into on top of hdfs by using hadoop fs command it shows "command not found".

Can anyone explain what is the problem and what we have to do to run hdfs commands?

I bought the Asus Zenbook UX31E a few days ago and installed Ubuntu 12.04. Everything works well, but the CPU temperature (and overall the machine) seems too hot and the fan works too often, even with moderate or no CPU load.

I understand that there where similar issues in the past, but I thought these where resolved (I had the same issues with a Dell and 10.04, but it almost went away eventually after some updates).

I've installed Psensor and it reports around 81C, after a fresh boot and minimal load (12% CPU) and the fan is constantly on.

Anyone with suggestions?

Note: This laptop only has an Integrated Graphics Chip.
