How to upgrade the debian version of an opsi server ?

[bourhis]

Hi,

I'm trying to upgrade my debian version from "buster" to "bullseye" and, if the Debian upgrade works well, I'm having a problem with "Opsi" : I can't login "opsi-configed" any more !

Is there a specific method to do this upgrade ? Any post-configuration to make ?

Best regards.

The easiest way to fix that is probably to correct the sources in /etc/apt/sources.d/opsi.list and then run `apt update` and `apt install --reinstall opsiconfd`.
