How to upgrade to a new installed gitlab runner version?

Question

I try to update my single gitlab runner from 11.0 to 11.3.1 and followed the instruction on the gitlab doc.

sudo apt-get install gitlab-runner will confirm that I have the new version installed:

gitlab-runner is already the newest version (11.3.1).

The last updates like 10.* to 11.0 worked absolutely fine but this time the runner still stays on 11.0 (in -help and gitlab-ci web ui).

A restart of the runner don't change anything so it looks like I miss a major step for the update some how.

It would be great to find out what I'm doing wrong, thanks in advance. :-)

OS: Ubuntu 18.04.1

(I'm relatively new in the linux and gitlab world so it could be something obvious)

Used update command:

# For Debian/Ubuntu/Mint
sudo apt-get update
sudo apt-get install gitlab-runner

Ok the problem was solved by using the manual update described at:

https://docs.gitlab.com/runner/install/linux-manually.html

Stop the service (you need elevated command prompt as before):

sudo gitlab-runner stop

Download the binary to replace Runner's executable:

sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-386
sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

You can download a binary for every available version as described in Bleeding Edge - download any other tagged release.

Give it permissions to execute:

sudo chmod +x /usr/local/bin/gitlab-runner

Start the service:

sudo gitlab-runner start

"latest" - may install a beta so it is important to select the right tag (also described in the link)
