Two minutes ago I was able to install timekpr-next in Ubuntu 20.04.4 VM without any problems at all.
I don't know what to suggest... Can you try to uninstall existing version and download the package and install it manually using dpkg?
Some long time ago another user had this "installation stuck" problem too: https://bugs.launchpad.net/timekpr-next/+bug/1893280
Althogh it was nothing related to timekpr, the solution surprised me, but it worked for him...
