Thread:Project:Support desk/Upgrade gerrit to 2.9/reply (2)

This basically is the same as the Gitblit question, which you brought up a few times in the past already. See Thread:Project:Support_desk/Update_gitblit_on_wikimedia_git and especially Thread:Project:Support_desk/update_git_site for the answer. Apart from that the question is not related to the function of the MediaWiki software itself and so is displaced here.
