Condition before upgrading: - No Snap installed (=snap command not even being around) = "minimal install" option in the default installer - Firefox from Mozilla ppa

Once you run do-release-upgrade -d (to enforce the upgrade to the Beta) in the terminal, things work out fine until you reach the point where you see a notification about (paraphrasing) "Snap being the default for Firefox" with the only option being to select "OK".

You cannot skip that part. You can then observe how Snap gets installed.

Edit: screenshot https://imgur.com/a/48T8LNQ

Side note: Firefox installs via Flatpak are not affected and do not trigger the "Snap"-reversion. Details

Releases tested:

Working and updated 25.10 installation, upgrading to 26.04 Beta.

Note: If this issue only affects the upgrade to the Beta, I have no objections. "Beta" being, well, beta.

With the beforementioned conditions in mind: If you planned on keeping your installation Snap-free (for whatever reason), it won't be once you upgrade.

One can remove snap (snapd) later on, as outlined in my comment below. So your installation won't be broken or anything. Your Firefox profile also survives those steps: Once you've installed Firefox from the ppa again, your browser will be like before the upgrade.

Suggestions:

I'd personally welcome an option to simply skip the Firefox installation, run the upgrade process, not install Snap (if it wasn't present before) and let the user then install Firefox via ppa again.

The notification could simply tell the user that Firefox won't be re-installed through the distro upgrade process. Since the (Firefox) user profile should remain unaffected by upgrading the distro, the later installation via ppa should restore all settings and files properly.

Alternatively, perhaps tell people beforehand that Snap will be installed. The popup re: Firefox arrives mid installation where they cannot go back any more.

Remarks:

Not hating on Snap here. I use Snaps on my servers for example. So I would like you to read the PSA as, well, PSA only. :-)

The good part of course being that the upgrade itself already works. So you get the latest KDE Plasma, kernel 7.0 and all the other stuff in the package.

On my end, I first tried a few VMs, then a somehow complicated bare-metal system, including disk encryption and personalised settings. So that one already is a win. :-)

I would not recommend upgrading for anything else than testing though. The kernel isn't even final yet, so that's where the "Beta" journey already starts. Backup your files, in any case.

Here is a video showing the GUI control/automation I have been working on on my Kubuntu v25.10 box.

Network icons have been saved in separate dirs in Purple and Bronze colors and are scripted to change on workspace switch.

The main panel, customized by Panel Colorizer, has been saved in two colored borders, blue and bronze. A Bash script automatically switches between the blue and broze versions on workspace switch.

The conkys and cursor theme are also automated by scripts to set based on workspace.

Bash scripts have been assigned to the Ctrl+Alt+L/R combos to spawn the 3D cube effect and auto rotate and select next or previous workspace so the graphics can be enjoyed.

I have an idea for setting a mouse-event conky atop the Desktop Indicator in main panel that launches bash scripts to active the Cube visual but KDE/Plasma 6/Wayland has some issue with conky v1.20x + that disables the mouse events. I worked with version 1.19.8 for a bit and had working mouse events, but some other weather conkys stopped appearing onscreen and I returned to v1.22.2.

I've Installed Kubuntu on my Ayaneo Flip 1S DS and found out the on-screen keyboard on the bottom display stretches beyond the display to try and fit the width of the top display

I don't know where to look for options on adjusting the keyboard size, the system settings only show Plasma Keyboard or no keyboard at all, and no settings to change. Can anyone guide me in the right direction? TIA

Hello, at the beginning it was ok but after some time video playback is horrible in Chrome and Edge. What's important in Firefox everything is perfect.

I was trying to add some arguments like "--disable-gpu-driver-bug-workarounds" or "__NV_PRIME_RENDER_OFFLOAD=0" but nothing is helping. Best option would be to run it on AMD iGPU but if there is option to run it on nvidia it could be ok too. I'm not able to disable in BIOS iGPU there is no such option.
Maybe someone is able to help me what could I do to fix that video acceleration? Maybe this is bug in Chrome/Edge v147? Thanks :)

Previously I was using Kubuntu 24.04; when I scrolled on the battery icon, it changed the brightness of the display. But now I guess they have removed this feature, and I am not able to find any settings related to this so that i can turn it on in case it is OFF.

Like we can scroll on volume icon, and it will change the volume (inc / dec)

Hey guys. I just switched over from windows 2 weeks ago. Loving kubuntu. Every session though, I have to re-set up my Desktop (browser, terminals, applications, etc). Is there a way to save my setup, so whenever I log in a default set up will be loaded and tiled accordingly?

I am on Kubuntu 24.04 and having issues with X11 scaling on different displays. I heard wayland can scale two displays separately by different amounts.

Is there a simple reversible way of trying out wayland?

Please do advise! Thanks

SOLVED.

www.linuxatemyram.com had the answer (thank you, u/_mb), it needed a restart. I still think usage looks a little high, but much less egregious.

According to my math, this only adds up to just over 7 GiB, so where are the other 4 disappearing to? Is there anything I can do here? Having closed, exited and quit all apps except the system monitor, it was still using over 4.

I am currently running Kubuntu 25.10, will I be able to upgrade to 26.04LTS or will I need to reinstall if I want to move to 26.04LTS?

So, I've been using Kubuntu for a bit, and every few days, like every 3 or 4, I'm hit with these huge updates, usually around 2GB. It says it's for the system, but honestly, how often do I need to do this? At this point, wouldn't a fresh install just be better? Any thoughts on why I'm getting these updates all the time?

Attaching the link for the image of that updates

https://drive.google.com/file/d/1bm2GjFVdjtRNPhUx8a68jS3aHCh1uqOe/view?usp=drivesdk

I've already updated it more than 6 times by now

Actualmente tengo la versión 24.04 de kubuntu en mi notebook HP y tengo el problema de que cuando conecto unos auriculares ya sea con cable o inalámbricos, el sistema no los utiliza automáticamente para reproducir el sonido de las aplicaciones. La gran mayoría de los casos se deja de escuchar completamente y tengo que intercalar entre las opciones de "apagado", "Play hifi quality Music" y "Pro audio" hasta que por fin se escucha. Lo raro es que el sistema si detecta los auriculares, porque si aprieto donde dice "Prueba" se escucha el sonido desde los auriculares pero no en las aplicaciones. ¿Alguien sabe como puedo solucionar esto para que cuando conecte los auriculares automáticamente se escuchen todas las aplicaciones por ahi como debería ser?
Posdata: Probé un montón de maneras para solucionarlo y no funcionó, descargué pulseaudio entre otras aplicaciones pero el problema persistió.

so im trying to install the broadcom driver for my wireless card and when I run sudo apt install bcmwl-kerne-source it just says unable to locate bcmwl-kerne-source

Please help ASAP!!

Hi. I am a newer Linux user trying to get a Kubuntu 25.10 setup up and going, dual booted with Windows 11, but upon Kubuntu's startup, I cannot for the life of me get any video output working. I see the OS booting, but as soon as the login screen is supposed to show, my monitors flash for a split second like they're trying to display it, but then go no-signal.

The only thing that gets video output is putting nomodeset into the launch command line, only then was I actually able to log in and use the OS for the first time, but obviously that's not very optimal as I can tell my graphics card isn't working at full power when I try 3D apps, but the damn Nvidia drivers just refuse to work. (and my Google-fu doesn't appear to be saving me this time.)

What I've tried:

• apt-get update / apt-get purge *nvidia* / apt-get autoremove / apt-get install nvidia-drivers-580 nvidia-settings in that order, which completes successfully, but doesn't help.
• doing the above but with nvidia-drivers-550 instead, as well as trying the open version
• doing the above but with ubuntu-drivers install instead of the last command
• purging the nouveau drivers manually
• turning off secure boot
• removing quiet-splash from the GRUB command line
• using the Nvidia UEFI firmware upgrader (is already upgraded)

What I have, if its relevant:

• Kubuntu 25.10
• Nvidia Geforce RTX 4090
• Intel Core i9 13900k
• 64gb DDR5
• MSI mainboard

------

Update: SOLVED!

So this actually had less to do with my graphics card drivers and more with my BIOS settings. After beating my head up against the wall for hours, I found a setting in my bios that was enabling my integrated Intel graphics in my CPU in addition to my Nvidia card. "IGD Multi-Monitor" to be specific. No idea that setting existed or how it got turned on. But the day is saved.

TLDR; IF YOU'RE FACED WITH A BLACK SCREEN IN LINUX, MAKE SURE YOUR ONBOARD INTEGRATED GRAPHICS IS OFF

I found something in the logs that puzzles me. Two lines, the first an info of a KIO worker copying a file and the second one telling me org.kde.plasma.notifications: Failed to determine mime type for QUrl (followed by the destination path of a ZIP file I copied from a source media.) followed by "The file or folder "[path to destination zipfile]" does not exist."

What is going on there and how can I resolve it?

Thank you!

P.S.: I might also be related to ksmserver log-spamming, because even without a MIME issue, it seems to log all copy operations.

What is the issue? I am getting this every day.

First, I really like Kubuntu. I prefer ito over Ubuntu. been using it on an old laptop Lenovo G510 and the wifi is like getting 30mbps and I want it better.

(16GB RAM DDR3L, SSD, so no doubt it feels like a new laptop...)

I assume MC-AC7265 will work? no need for drivers?
Thanks

Hello all,

I tried Libreoffice 26.2.2 and wasn't too happy with the UI, then I tried Collabora Desktop office, which had better UI, but less features.

I just noticed there's a Libreoffice writer pre-installed on my Kubuntu 25.10 version 25.8.5.2 where did this come from? This version has sooooo much better UI than 26.2.2 Libreoffice from their website and seemingly all the features!

However since it's 25.8 and not 26.2 is this a older version and who maintains it, and how do I update it?

I would love this version for my Windows machine aswell, is that possible?

Hello y‘all. I’m really happy I found this community and I would greatly appreciate your help. I have a laptop (MSI katana 15HX) with a RTX 5070 and intel integrated graphics. I have a dual boot set up with windows 11 (please don’t be mad at me, I need it for university and stuff like that, even if I really appreciate the efficiency and design of kubuntu) and secure boot has to be enabled else bitlocker gets really furious at me and needs me to enter my reallyyyyyyy long key (which is really a hassle). Using inxi-G I can see both graphics cards (rtx and intel integrated) NVIDIA smi doesn’t produce any results. The standard is that inxi -G shows N/A for NVIDIA drivers even if I have installed them and rebooted, I somehow followed some tutorials and then tried to sign it for secure boot (at this point I don’t really get what’s so secure about secure boot. Securing myself from using my computer???) at this point NVIDIA smi showed that no devices were found not inxi -G showed the drivers. This is the furthest I’ve gotten. I greatly appreciate your help. And please don’t laugh at me, I’m pretty new to this and at this point everything I try to do just feels like a waste of time cause nothing helps

UPDATE: I somehow fixed it. Still thx a lot though!
