What's wrong there? It's running on a Ubuntu 12.04 and I had an isue during the update with receiving of packages repoted at https://github.com/gitlabhq/gitlabhq/issues/5694. Not sure whether it's related.

Answer 1

The issue was a wrong gitlab.yml file. During merging the changes from 6.2 I put in a wrong indention. Having this fixed, it's running now.
