Hello,
according to the Upgrade recommendations i have to do several steps to upgrade to the latest version. (8.x->9.x , 9.x->10.x, 10.x->11.x )
Since i used the Omnibus installer is it enough to just “sudo apt-get install gitlab-ce” and the the installer does the rest for me or do i have to install somehow specific versions via apt-get?
thanks in advance 
edit : running on Ubuntu 16.04.1 LTS
