Comment 6 for bug 1963762

you are right, it hangs at "systemctl start timekpr".

systemctl status timekpr

timekpr.service - Timekpr-nExT daemon service

ps -ef | grep timek

alex 88879 55454 0 17:39 pts/1 00:00:00 systemctl start timekpr
alex 88913 88906 0 17:40 pts/0 00:00:00 grep --color=auto timek

I opened as new window and typed sudo timekprd. It is working.

Now, I can open timekpra with superuser rights. Yes, it does work in manual mode.
