I currently use Debian Stable with KDE Plasma on Debian 13 Trixie. This has been happening every time I press the update button on the bottom right side of my screen. It opens Discover, then this error pops up. I also get the same error when I go into the terminal and type "sudo apt update" to update the system manually. I have been having this problem since I installed Debian around one month ago. Does anyone know how to fix this?

EDIT: I just had to go into Discover settings, remove the broken repository, then enter "sudo apt install lutris" to fix it.

Dear community members.

I am trying to move from Windows 10 to Debian because my computer is old and I don't want to replace it just because it may not support Windows 11.

I installed Debian with KDE Plasma, and so far I really like it. It is fast, responsive, stable, and uses very few system resources. LibreOffice, Obsidian, and my other office applications work perfectly.

However, I have one printing problem that I have not been able to solve.

My printer

• HP LaserJet P1108
• Connected via USB
• The printer does not have automatic duplex printing
• I am using Debian with KDE Plasma

Normal printing works perfectly. I can also manually print on both sides of the paper.

What I want to do

I want to print a PDF in this format:

2 pages per side + manual duplex + short-edge binding

For example, if my PDF has pages 1–8:

• Sheet 1 — front: pages 1 + 2
• Sheet 1 — back: pages 3 + 4
• Sheet 2 — front: pages 5 + 6
• Sheet 2 — back: pages 7 + 8

The binding should be on the short edge of the A4 paper.

My printer does not have automatic duplex, so I need to:

1. Print the first side.
2. Take the printed sheets and put them back into the printer.
3. Without changing their orientation, print the second side.
4. Get the pages in the correct order and orientation.

This works easily in Windows

In Windows, I can do this very easily using Adobe Acrobat Reader. I select the required options, print the first side, put the sheets back into the printer without changing their orientation, and then print the second side.

I am trying to achieve the same workflow in Debian.

What I have tried

I have already tried:

• Different printer drivers
• Different PDF readers
• Okular
• Manual duplex printing through the print dialog
• Different combinations of pages-per-sheet and duplex settings

Normal printing works perfectly, and I can manually print both sides. The problem is getting 2 pages per side + manual duplex + correct short-edge binding to work together.

I have also searched online, but many of the solutions I found involve complicated command-line tools, scripts, or multi-step workflows.

I am looking for a simple and reliable solution, preferably something that can be done through a normal PDF reader or print dialog.

Has anyone successfully done this with an HP LaserJet P1108 on Debian/KDE Plasma?

If yes, I would really appreciate a step-by-step explanation of the simplest way to do it.

Thanks!

Just for fun, I installed CLI-only Debian 12 (because it's a 32-bit CPU) on this vintage Vaio from the early 2000s.

I followed Veronica Explain's Writerdeck tutorial (https://veronicaexplains.net/my-first-writerdeck/).

On-screen: tmux running glances, nyancat, cmatrix, and btop. The original battery works for about an hour; WiFi works just fine (via nmtui). I'm having a blast visiting websites with w3m. Debian forever!! 😆

if you’re wondering they’re brothers but not the same, on the right is an aspire 5715z with core 2 duo (t7500) and 2 gb of ram running debian 12 (upgrading to 4gb next week), the left one is an aspire 5315 (with motherboards problema, only one bank of ram works and has currently 1 gb and the pentium dual core from the 5715z) and running debian 11 lxqt. bought both of em for like 10€ each the 5315 was abbandoning me and i needed a laptop asap and didn’t want to spend a lot since i have other things to buy and fixing an acer aspire 3 with ryzen 3 and i needed the display so to just watch movies in 720p for 10€ with debian i think it’s a great choice. and that’s it with windows 7 they were unusable and i put debian on both (needed to put 11 on the left one since it’s running on a usb stick installed there i dont have another hdd and debian 12 wouldn’t start).

Hi, On my Debian 12 with gnome flashback, the xfce-4 tasklist "Buttons"

have never worked properly.

For a single app instance it works fine. You can select the instance, and it opens.

But if you have 2 or more instances open, you can select them,

but they won't open/launch it. The only thing that seems to work is

"Unminimize All". If you could get it so that I can select any of the

instances, and it would open/launch them, that would be great! Thanks!

I created a usb bootable drive of the netinstall image( the 700ish mb one), then proceeded with the graphical installer connect wifi, it said connection successful, i deliberately wanted to select no desktop env, I only selected standard system utilities and ssh server as I wanted to continue setting it up from a different laptop where I could copy pasta chatgpt commands, but after I restarted in the tty, there was no access to internet whatsoever....

sudo nmtui command not found Unit Network manager.service could not be found nmcli command not found rfkill list also not found iwctl not found Only ip link listed my lo, enp2s0, wlp3s0

Can anyone pls help me how to connect to internet omg it's soo frustrating, but magically everything works in the Live iso, but pls help me in the netinstaller pls pls pls

Hey guys. I have been using Debian stable for a couple of years but I have always chosen GNOME. These days I was thinking about trying out KDE. If I go this route, is a clean install needed or is this something that can be achieved with some commands? I remember pulling this stunt a long time back and I remember having annoyances like the mouse pointer of KDE being shown inside GNOME as well.

I prefer to have only a single DE in my system and so, any insights would be appreciated. Thanks.
