Gogs, an alternative to Gitlab
Hi, GitLab CEO here. Installing GitLab should take only 2 minutes with the Omnibus packages available on https://about.gitlab.com/downloads/Upgrading GitLab is as simple as:    sudo gitlab-ctl stop unicorn
    sudo gitlab-ctl stop sidekiq
    sudo gitlab-rake gitlab:backup:create
    sudo dpkg -i gitlab_x.x.x-omnibus.xxx.deb
    sudo gitlab-ctl reconfigure

And we're working very hard to make sure this is a flawless, uneventful & boring process for 100% of the users https://twitter.com/PentiumBug/status/569930640725946368 We're also working on a package server so you can just use apt-get to upgrade.
