unable to update gitlab-ce on linux mint 17.3

Question

I have gitlab-ce 8.6.6 on Linux mint 17.3.

Gitlab-ce is now upto 8.11.2. If I do an apt-get install gitlab-ce then it tells me that I am already at the newest version.

When I cat /etc/apt/sources.list.d/gitlab_gitlab-ce.list, it shows

deb https://packages.gitlab.com/gitlab/gitlab-ce/linuxmint/ rosa main

This address is no longer available. Running

curl -s https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

overwrites the above repository entry with identical entry and running

sudo apt-get install gitlab-ce=8.11.2-ce.1

gives me an error of

E: Version ‘8.11.2-ce.1’ for ‘gitlab-ce’ was not found

Is Linux mint no longer supported? Do I need to upgrade to Linux mint 18 (based on Ubuntu 16.04)?

Answer 1

And a few weeks after I tried this, it suddenly worked and showed up on update. So I presume that the mint repository went from gitlab 8.6.x to 8.11.x.
