Is anyone else on Kubuntu 25.10 still waiting for the 26.04 upgrade to become available through do-release-upgrade?

The ISO has been out for almost 3 weeks now, but my system still says no new release is available. Fully updated system, official repositories only.

Completely botched my install of Kubuntu 25.10 by chmoding the root directory to help troubleshoot a program that was installed on the root that wasn't working. I was trying to troubleshoot OpenOffice not working because it installs on the root and it just crashes immediately on launch, figured it was a permissions problem because or something related so I wanted to add myself to the root so that I could modify and make changes to it. That was a big fucking mistake and by the time I realized that it was too late. Any chance of recover or I am I just fucked and have to reinstall from scratch. I can't even back up my user folder to my 5TB Portable HDD. The filesystem permission are totally fucked up and I don't know how to fix it due to being new to Linux, any suggestions on what I can do to recover my system or at least my files?

I tried restoring to default permissions with the sudo chown 775 command or something like that, didn't work. Tried re-installing the corrupt packages by using recovery mode to get sudo ownership back (that worked, but I still can't log in due to the it being unable to find the var directory and my home directory is completely wiped from the root. My user directory still exists, so I tried backing up via Deju-due or on an external, that fails due to permission problems, trying to run it through a Live CD and currently having problems with copying with elevated privileges due an unknown error that Dolphin just spits out with no log or anything. Said that the directory creation failed, but no other information is specified.

My guess I'm just royally boned, unless there is another way I can backup my user folder to keep me data. Any help or suggestions would be greatly appreciated.

It wasn't too bad tbh, I back up my files in case this sort of thing happens. But yeah, everything just kind of broke.

I was about to do a do-release-upgrade, but I backed out last minute as I wasn't too confident proceeding. About a day or so later, I saw almost every app in my Discovery update channel needing an update for something Ubuntu related. It was like 2,000+ things to update. I thought that was weird, but tried to update anyway.

It crashed multiple times, and during the final try my audio drivers went out. I did a force restart (I know I probably shouldn't have, but I'm impatient) and I couldn't boot into the OS anymore.

I kept my 24.04 LTS drive so I just reinstalled and redownloaded everything, but good lordt that was annoying.

I have installed Flathub and want to get rid of Snap altogether. I have my main apps installed from Flathub now and the Snap versions uninstalled. However, Software Manager shows a few apps installed with names I don't recognise, possibly some sort of system apps? Plus snapd and a load of other snap admin stuff. How should I go about dealing with all this so I can remove Snap entirely?

I'm getting these lag spikes quite often on kubuntu. I hate them and I need some help to resolve them.

SO I fresh installed from 25.10 to 26.04. and have had constant issues with memory and boot.
My laptop is weak on RAM and I literally cant afford to upgrade. It has 8gb ram but 2gig is allotted to igpu. Processor Ryzen 3500U.
25.10 ran just fine. I could open 2 chrome windows with 7-8 tabs each with my chosen IDE like antigravity or Vscode. But now I contantly get notifications that memory crisis avoided and IDEs keep crashing. random hangs when doing more than 1 browser window + 1 IDE window. It will even hang if I try to install an extension or something heavy like tensorflow library in IDE while having 1 browser window open.

Today there was another issue. Kubuntu refused to load. after grub selection, it would just hang on Kununtu splash screen.
I tried booting from a Live iso to see if there are any recovery options but was unable to find. So I just tried normally booting once more and it normally booted. I dont know what is happening. Is the install bugged or Resolute is really that resource heavy on RAM.

I want to switch to kubuntu from pop is to try kde and just pop is having problems. I mostly want to stick with .Deb and flatpak packages and want something easy and we'll supported like I have been using so kubuntu was the easy choice.

But like I've heard that Ubuntu distros will just secretly swap your .deb for snap I don't know enough to have an opinion on snap but I don't like the idea of downloading one thing only for my OS to say no u actually downloaded this other thing

I am getting a new Lenovo P16s Ryzen AI 7 PRO 350 notebook.

Which OS should I run Kubuntu or Fedora? It's going to be used for work.

I only ever used Ubuntu/Linux Mint (and as a kid Arch based distros and Crunchbang, but that was long ago). I heard bad things about snap, not sure why that is. Can it be replaced with flatpak easily? Which would you guys pick and why?

As the time to upgrade my 24.04 LTS is nigh, I am wondering what issues I might encounter when moving to the new LTS - 26.06 - and are there any ways I can prepare to make it more seamless.

Can you share some general tips? Should I do-release-upgrade when it becomes available or rather install new version clean?

Maybe you know of any particular issues with some of the apps I rely on?

The apps I rely on day, and issues with which would cause me quite some pain, are:

• Slack
• Tidal (unofficial client)
• Nextcloud Sync
• Zen Browser
• Telegram
• Signal
• WhatSie (wrapper for WhatsApp)
• VSCodium
• Obsidian
• Proton VPN and Mail
• Betterfox

I have some CLI apps configured, but nothing difficult to reinstall quickly. I also use Steam and Heroic for gaming on the other PC. My PC has nVidia GPU and I use the official proprietary drivers for this.

Hi folks,

I've just done a clean minimal install of Kubuntu 26.04, and then installed both chromium and firefox. All fine so far, looks great and works well. However, I then thought it would be neat to export my passwords from a different system and them import them into these browsers. The imports fail for both: no permission to read the file. Even though it's right there with read permissions in my own home directory.

My previous experience with snaps wasn't the best, but I thought I'd give this another try, and I've been disappointed yet again.

Does anyone know if there's actually a way around this? How would a snap be allowed to read a file like this? Is this a bug in the snap, or something which needs configuring manually? I'd have expected something so basic to just work. Is anyone using these snaps, or manually installing .deb packages instead?

I thought after spending 15 years as a Debian developer would have been enough to figure this out, but this is a new complication I know nothing about, so any suggestions would be much appreciated.

Thanks, Roger

Hello. After a 6 month trial run I'm planning of fully redoing my system and nukeing the Windows partition and I was considering going for the minimal install so I could have the cleanest possible install with the most control in terms of what software I have installed from the start.

I know I won't have a browser or office suite but none of that particularly concerns me. That's all visible and I can handle installing it all on my own. What I'm mainly interested is the background stuff that I might not be able to see at a first glance or in a test run in a VM, namely codecs and any other stuff that might unexpectedly complicate my life down the line by not being there. I know drivers are part of the kernel and I have an AMD GPU, so that shouldn't be an issue, but I don't know if there might be things I'm not even aware of. I only have 6 months of actual Linux experience to work with.

So, if you've used the minimal install, what were your experiences with it? Did anything come up that wouldn't have on a normal or full install? Or was it just the same with a bit of extra work to set things up at the start? Any advice that might be worth knowing?

The PC is supposed to be a general-purpose one, so some work (mainly with documents), browsing, communication, and gaming.

Hi third week on kUbuntu it's going great but when I was playing bg3 with my friend the whole system locked up yet I could hear the call still

No way to open a task manager or anything

I saw something pop up after a whole in black screen about Io errors for lots of systemd services and in journal I saw something about squash

I went back to windows for now but id like to avoid that

Is there way to get a blue screen with details instead of total lockups or something to explain how to fix whatevera happening

I haven't upgraded to the new kUbuntu yet I'm on the last release

Cheers

similar to this, but its kubuntu flavored. basically, i got this old laptop (Dell Lattitude 5580, BIOS is at v1.39) i bought off ebay for the sole purpose of being my backup computer in-case something about my desktop goes bad (hardware failure (natural/over-time or power surge gone wrong), software fuckup, aliens, etc....). now it can use Windows 10 (has the stickers on the back and everything), but i've messed around with various linux flavors in VM's long enough that i feel like giving it a go, so i grab the 1 TB WD_Blue 2.5" laptop-sized HDD i was using for a PS3 (have long since chosen to sunset the console) a while back, and put it in the laptop, made sure my laptop was set to UFEI mode (secure boot turned off, fastboot set to Thorough(which i guess is considered the "Off" mode on different laptops/desktops?), and i had a bootable Ventoy usb done up (partition table set as GPT) with the kubuntu iso inside. booted it up, did the thing, and installed kubuntu to the 1 TB drive. i made sure to confirm that the hard drive was GPT formatted, all the partitions looked normal enough, then i shut the laptop down, removed the usb, and booted it up.....and i got a "no bootable device found, press key to reboot"

i am at a loss on what to do next to get this to boot right. it was easier to do this with a VM, but if i end up choosing to make my desktop either a dual-boot setup, or switch from Windows (desktop) to Kubuntu (desktop) or any other possible linux flavor, then who's to say i won't run into this problem as well?

.....sooooo.....wat do? halp pls?

Ok, so I used to be an IT expert, and I did have a Linux box for a while (forget which distro), which I accidentally bricked and could never fix, so... that was the last time I used Linux. That was well over a decade ago. Maybe two.

Due to... MS things.... I'm wanting to NOT go to 11, and considering going to Linux, which shouldn't be too hard software wise as most software I use regularly also has a Linux version.

But.. decades. I've downloaded Resolute Raccoon (love the name) but the install instructions are for a CD. Now... I have tons of CDs, but my current system doesn't have a drive. I can still run it on a USB key, right? I'll need to get a bigger key than what's laying around, so first question would be - suggestions for key size and should I only get one with newer versions of USB, 30. or greater?

I've never run Linux as a virtual machine, so unsure of requirements there.

So, second question might be - which install method should I use if I want a complete testing environment, where I can use all my apps, including saving data. The PC itself has PLENTY of space across multiple drives and drive types.

Feel free to offer any other pertinent advice. The system is capable, the user... used to be but is more than rusty, lol. Been an "appliance user" most of the time for more than a decade, but really disliking where MS is going so I need to 'go elsewhere', and I'm not interested in the fruit :)

Oh, and I'm running a dual monitor BOX, not a laptop.

Update: Ok, I think I used Rufus to install Kubuntu on a 1TB SSD I'd forgotten about. So, yay but... maybe i'm just brain dead today but... what now? Windows can see it in disc manager but (not surprisingly) not in windows explorer. So, assuming i have a nice new Kubuntu bootable drive ... what now?

Like the title says, I would like to ensure that the desktop environment cannot update.

I would like to be able to update all the other packages (either via apt-get update/upgrade or via the discover store) as usual. My main concern is that I have a lot of system files modified that aren't designed to be modified, and I don't want to risk certain system files being updated to a pre-compiled version. I want to make sure that plasma cannot auto update, and that I cannot update plasma by accident.

I'm using kubuntu 26.04

Edit: I'm well aware of holding apt packages. I was hoping there was some way to ensure that plasma can't update to 6.7, 6.8, 6.9(nice), etc. unfortunately it's looking like this isn't possible without holding back a bunch of packages which I'm already aware is a bad idea (specifically holding back system packages)
