In the Release published by the aptly repo of tools-services-01 there is some issue.
This is what apt-cache policy reports:
1500 http://tools-services-01.tools.eqiad.wmflabs/repo/ trusty-tools/main amd64 Packages release o=. trusty-tools,n=trusty-tools,l=. trusty-tools,c=main origin tools-services-01.tools.eqiad.wmflabs
The o= and l= properties are weird. Let's review this, since this may cause some issue with code that works with repositories (like T181647)
