WIP: gnome-shell CI
Setup CI to build gnome-shell on Ubuntu 18.04.
Eventually, this should serve as test and as documentation of how to build the full GNOME Shell stack on Ubuntu LTS, i.e. the jbuild steps and a list of packages that have to be installed manually.
Currently, I have the issue that with
jhbuild --no-interact the apt frontend still asks for interactive input.
@creiter You managed the original configuration. Any idea of how I can entirely avoid interaction within the CI?
