Upgrade Zuul on scandium to 2.5.0-8-gcbc7f62-wmf3jessie1
Closed, ResolvedPublic


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.

The new version is already in

$ apt-cache policy zuul
  Installed: 2.5.0-8-gcbc7f62-wmf2jessie1
  Candidate: 2.5.0-8-gcbc7f62-wmf3jessie1
  Version table:

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.


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.

Solved by @elukey but that does not fix it :( I have screwed up the package and the shebang is not updated properly bah.
