Hi,
We were running gitlab package in debian stretch with some security
patches backported. But we could not backport all security patches
because some were very complex fixes.
Now we are on the latest security release. Most of the dependencies are
available from stretch-backports but some are blocked by transitions.
You can install the new version from
https://people.debian.org/~praveen/gitlab/
You can see the current status of getting gitlab 10.7.6 to official
stretch-backports here

Thanks
Praveen
