Maybe during upgrade of the appcenter package because the cache file is removed in the postinst?

Comment 3 Florian Best

Reproduce:
pkill -f appcenter; rm /var/cache/univention-appcenter/.apps.en.pkl; touch /var/cache/univention-appcenter/.apps.en.pkl;

I am able to reproduce it. With the latest version, it is gone. But the error seems to be Pickle related, this is not an issue with the new JSON cache.
