Dear all,

I'm not really skilled with proxmox, but I want to update my system.

My pve is currently running at V7.4-17 and I want to update to V8. After running pve7to8 I get one failure:

FAIL: Found mixed old and new package repository suites, fix before upgrading! Mismatches:
found suite bullseye at in /etc/apt/sources.list:1
found suite buster at in /etc/apt/sources.list.d/pve-community.list:1
found suite buster at in /etc/apt/sources.list.d/pve-community.list:2
found suite buster at in /etc/apt/sources.list.d/pve-community.list:3
found suite buster at in /etc/apt/sources.list.d/pve-community.list:4
Configure the same base-suite for all Proxmox and Debian provided repos and ask original vendor for any third-party repos.
E.g., for the upgrade to Proxmox VE 8 use the 'bookworm' suite.

How can I fix the problem?

May I exicute
sed -i 's/bullseye/bookworm/g' /etc/apt/sources.list
and would this solve that?

Many thanks in abvance
Thomas

The first (bullseye) looks normal for PVE 7.4 (Debian 11, and you will change that to bookworm for Debian 12/PVE 8).
However, you have several other non-standard repositories that are still using buster (Debian 10/PVE 6). Maybe update those software packages first to Debian 11/PVE 7.4 and make sure that the software still works and how to upgrade those to Debian12/PVE 8? Since those don't come with Proxmox, I know nothing about those.
 
Before you do ANYTHING, make a full backup of your system so you can restore if something goes sideways.

If you have never done an in-place upgrade like this before, I would strongly recommend a fresh install to a new disk instead and restore your VMs, etc from backup as you would likely be better off in the long run.

Personally I did a 7-to-8 upgrade in place, but have had to keep booting from an old 5.x kernel to support my 4x 10Gbit ports that are non-replaceable on the motherboard. However I have been running Debian and derivatives for decades, and it's not my first rodeo.

Doing a fresh install and keeping the old disk handy will also give you a way to backout of the upgrade experiment fairly easily just by booting from the original disk.
