Critical Python Update: How Soon Will it Be in Kubuntu 26.04 LTS?

DinoNerd — Thu, 22 Oct 2026 17:36:14 GMT

Multiple sources tell me that Python has released emergency updates thanks to a significant security issue. See e.g. https://www.linuxcompatible.org/stor...ate-authority/

Kubuntu 26.04 seems to include python3.14. The patched version of that is 3.14.9 After installing all pending updates on my 26.04 LTS system, but not yet rebooting, I'm at 3.14.4

Well, I didn't really expect the critical update to make it through ubuntu and kubuntu distro updates in 24 hours.

My questions are:

- approx. how long should this take?
- what are best practices for a kubuntu user in this case? Should I be replacing the system provided python3 with one direct from the python project?

Related, it seems that in a ubuntu derived release, an update to ca-certificates might solve the underlying problem, but I have no idea what version would be required, or whether it's out yet. (See e.g. https://askubuntu.com/questions/1570...an-updated-uni)

My system is probably relatively safe, with my site behind a firewall - unless I use pip. But I'd like to get this fixed ASAP.

External NTFS HDD only mounts from terminal

LinuxNewbie — Tue, 20 Oct 2026 21:25:09 GMT

I've got this external, NTFS-formatted HDD which won't mount from the "Disks & Devices" menu.
I cannot reformat to ext4, since I need it to be cross-compatible between with Windows at the moment.
Pressing mount returns "Could not mount this device" and checking for errors returns "This device has no errors".

I keep having to mount from the terminal (Konsole) using the following command:

Code:

sudo ntfsfix -b -d /dev/disk/by-id/usb-IB-_366-C31_123456789150-0:0-part1

After typing my password, I get this output, which makes it look like the drive is in perfect, working order:

Code:

Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
Checking the alternate boot sector... OK
NTFS volume version is 3.1.
Going to un-mark the bad clusters ($BadClus)... No bad clusters...OK
NTFS partition /dev/disk/by-id/usb-IB-_366-C31_123456789150-0:0-part1 was processed successfully.

The drive can then be read from and written to with no problems.

Any idea what the problem is?
Thank you!

[System]Lock Screen Time format, edits not changing?

rec9140 — Tue, 20 Oct 2026 03:08:09 GMT

Doing my normal settings changes... and getting correct 24H time, I change the QML in

/usr/lib/x86_64-linux-gnu/qt6/qml/org/kde/breeze/components

Clock.qml

Basically following, the below, but updating the path, as above,... since.. oh don't get me started... any way...

https://askubuntu.com/questions/7831...24-hour-format

No joy..

Edited, save , hit keyboard short to lock, no joy, still idiot time, log out, still no joy, idiot time, reboot, ditto..

Any ideas

If it matters, this is a test in KVM, don't think that should matter, but...

vanadiumboy — Tue, 20 Oct 2026 01:52:12 GMT

Problem 1:
If I do any calculation, such as
1 + 1 =

and I try to copy the result by clicking Edit -> Copy
the result doesn't get copied to the clipboard. This was working with Kubuntu 24.04

Problem 2:
If I press 1000
press divide
press 5
press the exponent button (it is written x 10^y on the button)
press 8

the result is 20,000,000,000 (20 billion)

instead of 2e-06

what does snapd.failure mean??

[Desktop]How to view all workspaces

frankp — Sun, 18 Oct 2026 03:19:25 GMT

In Kubuntu 24.04 a keyboard shortcut gave a view of all workspaces. I can't find how to do that in 26.04. I read that I should navigate in System Settings to Multitasking. When I click on System Settings I get only Quick Settings which doesn't give the navigation options a web search indicated I should see. Where can I set up workspace management to see everything on one screen?

[Post-Install]KDE Theme for RESTORATION of KDE3.x color, and brightness, and remove the gulag KDE4 and later stuff...

rec9140 — Sat, 17 Oct 2026 22:38:46 GMT

I am used to KDE having color, and being bright and not this gulag black and white look that took over in KDE 4 and later..

When ever I reboot the 14.04 machine I have for some reason or look at its GUI and see the BRIGHT COLORFUL look of it.. I get annoyed when comparing to current releases..

I miss that look, and even the BOUNCING ICONS on the boot screen from KDE3.. yeah I know its not likely that its booted too often to see.. but still...

I've searched for something that would bring that back vs the drab gulag theme and look of current KDE releases...

Any one got a theme that brings back this look

Thanks!

[Post-Install]Best practice for BLOCKING KDE 6.8 and borqing X11 setups and fixing Synaptic????

rec9140 — Sat, 17 Oct 2026 22:34:05 GMT

First, lets just get the ground rules everyone here is already familiar with my hatred and disdain of wayturkey. So Thanks, lets just leave that out of this and how its the glorious future of the Linux desktop, it is not. Full Stop. Additionally as it appears that 26.10 will give me one last update to some things v. the ESR 26.04, and my plan that 26.04 will be the end of the road.. unless some of the X11 forks appear in 28 to fix things... None of the various forks of X11 support the CORE FUNCTIONS I use, X'ng in aka X11 Forwarding & XDMCP. SonicDE and XLibre both are not going to support that, and/or have some issue with *buntus..

Soo.. leave the security drama theatre and wayturkey cheerleading behind.. Thanks!

So I decided to a test of 26.10 just to see what last hurray will be there since KDE 6.7 is the default... which led to the idea that hmmmm... any updates to KDE 6.8 via backports etc. would need to be BLOCKED. Probably a good idea for the 26.04 ESR's too!

So whats the best method of this, I do NOT WISH to hammer this with disabling backports repo, but just nuking KDE being updated beyond 6.7.x

I don't do auto upgrades and updating, period. But since I need to reeducate my brain to not just do this and then get a KDE 6.8 which will break X11....when I do the normal updates in the CLI...

I am looking at something along the lines of:

https://unix.stackexchange.com/quest...-not-available

But I am not an apt pinning guru, and I want to be sure I being granular enough that the 6.7 branch of KDE is fine to update, but anything beyond that is NOT acceptable. Now possibly others have figured this out and if kde-session-x11 is installed, that blocks things? Don't know... but I don't want to rely on that as in most cases people make choices which are opposite of my choices/desires in this space ala auto updates, upgrades and notifications of updates/upgrades available.. don't care thanks.

Basically which package(s) do I need to pin to the 6.7 KDE branch to prevent any changes to KDE desktop and thus X11.

So thoughts, ideas? Suggestions? on blocking KDE updates that would break X11

Next would be still synaptic is not allowing the search/filter bar as per the link as I've always done.. again, I though this was fixed in Debian and thus should filter down Ummm?? Bueller??

https://askubuntu.com/questions/7638...6-04-and-later

Or things are going to need to be hard purged, and reinstall a proper synaptic from:
https://launchpad.net/~nrbrtx/+archive/ubuntu/synaptic , at lest for 26.04 ESR...

This thing too is falling to one of those areas of people should leave things alone! I don't care what issue there is with libept or whatever.. urrhghghghghhhhhh. Just YOU don't use something, or use your system remotely etc.. doesn't meant there are not others doing so who have done so for longer than most of you likely have been alive too! urghghghghghg... ommmmmmmmmm....

Just for edification for other X11 refugees X11 was SUCCESSFULLY RESTORED in 26.10 for my KVM testing setup, and LightDM was installed to permit XDMCP along with Xephyr for that setup.

Well I am off to get some drinks, as this just pushed my buttons too much... ommmmmmmmm... clink... sllooosh..

[SOLVED]Dolphin - bug fixed in Kubuntu 26.04

vanadiumboy — Sat, 17 Oct 2026 21:22:57 GMT

Man, before it was annoying. Maybe someone listened to my bug report.

When you have folders starting with "a", for example

aa1
aa2
aa3
aa4
aa5

and I choose aa4 with my mouse, aa4 gets selected.
When I press on 'A' on my keyboard, instead of going to the NEXT folder starting with 'A', which would be aa5, the selection would jump back to aa1.

Whatever the first letter is, whether it is a file or folder, that was the previous behavior.
They fixed it.

Now, I can have a folder with thousands of files and folder with various names. I can select some file or folder, press a key, and the search will start starting from that point.

[Pre-Install]Partition recovery after formatting and changing partition table

zahtar — Sat, 17 Oct 2026 12:31:10 GMT

Partition recovery after formatting and changing partition table.

Hello everyone, I would like to ask some help regarding partition restoring.

This is about my mothers laptop which I prepared for upgrade to 26.04 (from 24.04) but somehow I did the epic mistake not to copy the folder with all the files I had collected for the transfer

I realized my mistake shortly after starting the 26.04 installation which means that first:

I changed the partition table to increase the EFI folder´s size (sda1) from 100MB to 300 MB (I think) because 26.04 required me to do so.
Kubuntu 24.04 was on sda5, so I shrinked it a bit and moved it to the right. I did that so I could also move the sda2,3,4 partitions (windows etc) to the right. This means that I understand/handle/describe the partitions in a linear way, just like kparted shows on its gui.
I chose regional settings etc, started the installation and after 10-15 minutes I realized my blunder and canceled the installation.

I am now booting the laptop live from the 2604 usb.

I have tried Testdisk with ¨deeper search¨ but it takes forever and does not find anything. I left it overnight. One thing here, the laptop went to sleep too, so I cannot be sure it worked 100%. I also tried RLinux but no good. It saw the old partition, tried to make an image but I do not find contents. Another utility I tried is Hetman Partition Recovery software but no luck.

Any ideas?

Graphics Drivers / Mesa help AMD

clammer — Sat, 17 Oct 2026 03:38:35 GMT

Currently on Kubuntu 26.04 LTS , installed and only OS, Plasma 6.6.6

I'm on an AMD computer and having what I can only assume are graphics issues- I'm not sure exactly what caused them but I guess either I installed an update that wasn't ready or the program itself updated to become slightly incompatible. A theory I saw is that the graphics card could be dying, but I doubt it since it's fairly new and it only has problems in very specific cases. (I'd rather be optomistic anyway)

I'm getting occasional graphics issues from openGL renderers, and suddenly Deadlock's been stalling after only a couple of minutes of play. Those are the only things I've noticed having problems so far (but that second one could be out of my hands).

Anyway, I've been trying to fix it but I don't understand what to do. I've looked at other help topics and they imply I don't use AMD drivers? I downloaded the .deb from the official website in case I need it but haven't done anything else because these other topics have me confused. I ran glxinfo -B | grep "OpenGL" and Mesa is 26.0.8, which isn't up to date as I checked... running flatpak list | grep Mesa shows it should be 26.2.4 but running flatpak upgrade says "nothing to do." sudo apt upgrade didn't do anything as it was all up to date, allegedly. Also, checking drivers in GUI in driver manager shows "No additional drivers available."

From what I understand Mesa is, itself, a driver for AMD systems using Linux? How would I update it to hopefully fix my problems? Discover also doesn't have a pending Mesa update. Is there anything else I should be doing? Please help, thank you!

libvirt group confusion? 991 vs 135

oshunluvr — Thu, 15 Oct 2026 17:46:11 GMT

This is an upgraded KDEneon install from 18.04, currently based on 24.04.

I was deleting a VM using libvirt KVM GUI and for some reason that I could not glean, it would let me delete the VM but not the storage image, claiming I didn't have permission. The VM itself was Kubuntu 24.10 I created a while ago. Looking into the images folder and all the files there are root:root owned and permissions the same. So I deleted the image file manually. Testing with other VMs, no problem deleting any of the other image files from KVM.

Anyway, this lead me to dig a bit deeper to see what I had messed up. I have mucked about with QEMU/KVM a bit in the past but have no recollection of what I changed except to move all the folders out of /var to a separate EXT4 partition so I could avoid using NoCOW and to make the installation file system more compact. I range from 10 to 20 or so VMs off and on, so it uses a lot of drive space.

What I discovered - and the point of this post - is quite a few of the folders and files in the virtual machine storage are set with group 991 but this group doesn't exist on my system. Additionally, there is a libvirt group in my groups but it's group number is 135. Preliminary web searches show that RedHat uses group 991 for libvert.

It seems probable that libvert as group 135 was already on my system before I mucked about with it and somehow along the way, KVM is configured to use 991.

I ran a "find" command to see if any files or folders on my system are group 135 and could find none.

I'm wondering if any other QEMU/KVM users on here are seeing the same as I am. Odd thing is I've had no problem using KVM until this deletion thing today.

I'm thinking I'm going to change the libvirt group number to 991 and adjust my user account if needed.
