If there are no updates available, "Loading updates" goes on forever

[Keks-Dose]

In the tab "Packages" tlcockpit loads the packages and displays "Loading database". This vanishes, as soon as the database has been loaded and the package names are listed.

Under the tab "Updates" the message "Loading updates" does not vanish in case there are no updates available. This is misleading, because tlcockpit does no longer load a list after some moments.

Current tlcockpit version from texlive 2018.

Interesting, I don't see this here. I get the following screen:

Can you please run with -d and send me the output?

Works again. After tlmgr update --list it displayed a list of 26 packages as skipping forcibly removed package. Cured by tlmgr update --all --reinstall-forcibly-removed. Then tlcockpit works as expected.

So, you'll know much better than me, some process removed the 26 packages and something went wrong.
