sources.list.d files don't appear to be up to date as they don't reference https://updates.software-univention.de/4.1/maintained/ 4.1-2/amd64/ Packages as your system.
Going to the package section of UCS shows several packages have upgrades, but if I try to update any package it fails with errors stating all the dependent packages need to be updated, removed, or reinstalled?
Is there an easy way to correct the system without effecting the UCS functions? Computer systems are not my occupation, so I don't work with this on a daily bases. I switched from Fedora to UCS to explore or hope to find a solution where I didn't have to tweak configurations each time upgrades was necessary.
Your help is welcomed and appreciated.
