Problem: Your Server Says It Is Out Of Maintenance But you Do Not Get Updates

Problem

Your UCS server tells your current version is out of maintenance and you should update to a newer version. But there are no newer versions shown to upgrade to.

Environment

Running univention-upgrade on the console does not show any available updates, either.

Solution

There might be no online repositories configured to use. Enable online repositories by:

echo > /etc/apt/sources.list
apt update
ucr set repository/online=true
ucr commit /etc/apt/sources.list.d/*
apt update

Afterwards, update should find new versions and you should be able to update.
