Comment 2 Dirk Wiesenthal

Fixed in
  univention-appcenter (6.0.10-22)

Looks like a timing issue where another process deleted the cache file (very small window, though).

Fixed by just catching the exception. The cache should be re-evaluated the next time it is accessed.

Comment 3 Felix Botner

please rebuild in ucs4.2-3

Comment 4 Dirk Wiesenthal

2017-11-23 17:52:21 CET

Rebuilt as
  univention-appcenter 6.0.11-1A~4.2.0.201711231631

except EnvironmentError:

but the Traceback is OSError:

is this the same?

(In reply to Felix Botner from comment #5)
> except EnvironmentError:
