Upgrade docs broken
In https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/8.1-to-8.2.md it states:
For GitLab Community Edition: sudo -u git -H git checkout 8-2-stable
This would be a good trick since there is no 8-2-stable branch on this repo. Did the branch not get tagged properly, or is this an error in the docs?
