As part of cleaning old zuul references on the Zuul merger (T103528), I got a patch prepared and upgraded the package on scandium T145057
Unfortunately the .deb package is wrong and needs a hotfix included in 2.5.0-8-gcbc7f62-wmf3jessie1
zuul (2.5.0-8-gcbc7f62-wmf3jessie1) jessie-wikimedia; urgency=medium
* sync with precise-wikimedia:
* Fix shebang of several scripts to point to the virtualenv.
Refresh 0002-Replace-python-shebang-with-python2.7.patch

Upgrade
Since we lack root access, we need operations to handle the upgrade:
ssh scandium.eqiad.wmnet systemctl zuul-merger stop apt-get install zuul systemctl zuul-merger start
Then trigger a job via Gerrit and check that /var/log/zuul/merger.log has useful output / job pass.
Rollback
Downgrade Zuul to 2.5.0-8-gcbc7f62-wmf2jessie1
This can be done at any time. It will pause CI processing for a few seconds while the service is offline which is really not a big deal.
