Hi Remco, there are easier ways to determine that. For example you can run:
apt install $( dpkg -l | grep 5.21.5 | awk '/^ii/ {print $2}' ) This command will try to update every installed package in version 5.21.5 (not totally bulletproof I admit). If a package cannot be updated, e.g. because no newer version is available, then this will be printed explicitly. So when you run this command and it says that certain packages are already in the newest version, then you know that the update is not complete. It can happen though that it finds a package that does not belong to Plasma, but this can be checked easily and happens only rarely. Try to run the command with 5.23.0 and it should list a lot of packages that are already in its newest version. -- Med vänliga hälsningar Patrick Franz
