The Beta-Cluster-Infrastructure is/has been used for the salt version bump. But the version from apt.wikimedia.org is pinned with a higher priority:
deployment-cache-text04:~# apt-cache policy salt-common salt-common: Installed: 2015.5.2+ds-1~bpo8+1 Candidate: 2014.7.5+ds-1 Version table: 2015.5.3+ds-1~bpo8+1 0 500 http://debian.saltstack.com/debian/ jessie-saltstack/main amd64 Packages *** 2015.5.2+ds-1~bpo8+1 0 100 /var/lib/dpkg/status 2014.7.5+ds-1 0 1001 http://apt.wikimedia.org/wikimedia/ jessie-wikimedia/main amd64 Packages 2014.1.13+ds-3 0 500 http://mirrors.wikimedia.org/debian/ jessie/main amd64 Packages
Additionally, the repos is a third party which is really not ideal.
Can we get rid of http://debian.saltstack.com/debian/ jessie-saltstack/main and inject the package under apt.wikimedia.org instead ?
