Comment 7 for bug 1963762

Ok, now we have to deal with systemctl command.
I do not have a "medicine" for this strange / unexpected hang, so we are experimenting here :)

When you install timekpr-next it will hang on starting during installation, just reboot at that point.

After reboot, check if timekpr has started, try checking processes: ps -ef | grep timek

Either way, next time you'll run update it will (most likely) complain that installation was not finished previously or smth like that, then, I think, it will offer to run "sudo dpkg --configure -a" or "sudo apt-get -f install" or smth like that... (I do not use ubuntu anymore and have forgotten about what it complains in that case exactly...)

Try running that, let's see whether it finishes then.
