xapian dependency for gitlab-ci
Currently the gitlab pipeline fails an release-3
: https://git.hack-hro.de/stadtgestalten/stadtgestalten/-/jobs/1830
I am not sure, why it worked before.
Probably we will need to either apt install python3-xapian
or add xapian
to the ´requirements.txt`. But maybe the latter requires additional libraries to be installed.
But maybe I just overlooked the place where we define the set of packages installed in the gitlab runner instance?
