Unable to upgrade to latest gitlab-ce on Linux Mint 17.3

Currently running gitlab-ce 8.6.6 Mint 17.3.
If I try to do a get-apt update or install then am told that it has the latest version.
If I run
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) for latest gitlab-ce?

I wouldn’t have thought so:

The link is where I went and run the commands and got the error message above.

Just tried the 8.11.3 version and same result. Following instructions in link. So curl piped through bash to run script. And then install but E: Version ‘8.11.3-ce.1’ for ‘gitlab-ce’ was not found.
I am obviously doing something very daft. But I can’t see what it is.
If I cat /etc/apt/sources.list.d/gitlab_gitlab-ce.list (updated today by above script) then

(comment) this file was generated by packages.gitlab.com for
(comment) the repository at https://packages.gitlab.com/gitlab/gitlab-ce

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

An https://packages.gitlab.com/gitlab/gitlab-ce/linuxmint/ does not exist which is probably why I get the install error. So perhaps the question should be why is the script adding a link that does not exist?

Just to add, I originally installed this via the mint software manager.

I suspect that the repository URL automatically created by scripts was wrong for Linux Mint.

Modify /etc/apt/sources.list.d/gitlab_gitlab-ce.list to use corresponding Ubuntu repository.

Following works for me!
Do not forget to do “apt-get update” after the modification.

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

deb https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu/ trusty main
deb-src https://packages.gitlab.com/gitlab/gitlab-ce/ubuntu/ trusty main

I did try that originally and it did not work. But then Mint updated their repository about a month after I wrote this to 8.11. So now it does work,

@kg86. Thanks, worked for me!
