Here is the content of /etc/apt/sources.list:

deb http://ftp.at.debian.org/debian bullseye main contrib

# security updates
deb http://security.debian.org bullseye-security main contrib
deb http://ftp.de.debian.org/debian jessie main
# deb-src http://ftp.de.debian.org/debian jessie main

Can anyone help me with this issue?

Thank you!

Hi,

is there any reason why you're using the debian jessie repositories in conjunction with the bullseye ones?

 

[BP2010]

hi,
no, not really. I just followed an instruction while I upgraded proxmox from v6 to v7. As you see. I don't have much expierence with proxmox or debian

 

[nunner]

Then I'd try removing (or commenting) the line

deb http://ftp.de.debian.org/debian jessie main

and try updating again . Here's [1] what a default config looks like for PVE 7.

Great thank you! The error is gone!!

May I ask another question?
I also did a dist-upgrade. The system told me that a lot of packages were not needed any more. I removed them. I hope I did not any stupid?

From man apt:

autoremove is used to remove packages that were automatically installed to satisfy dependencies for other packages and are now no longer needed as dependencies changed or the package(s) needing them were removed in the meantime.

so you should be fine . Glossing over it, I don't see any packages that would break things if they were removed. But generally, do read the list of packages before removing anything.

Thank you for your great help!
