Today i did the first update after i did a Ubuntu Inplace-Update from 16.04 to 18.04 and got this Error:
chown: cannot access ‘/opt/zammad/tmp/cache\_file\_store\_production/507’: No such file or directory
dpkg: error processing package zammad (–configure):

Errors were encountered while processing:
zammad
E: Sub-process /usr/bin/dpkg returned an error code (1)
What this means? The Directory is there and the rights are identical with the other Folders.

Hi @anon43131755
befor you install your zammad updates, try this:

I’ve tried:
“apt-get install libimlib2 libimlib2-dev”
This seamed to be the problem. Thank you very much.
