I'm trying to install Gitlab Runner inside my cluster in Azure Kubernetes Service (AKS), but I have 2 errors:
Helm Tiller doesn't appear in the application list of Gitlab CI:
Most of tutorials tell that it has to be installed, but today it is not even proposed as you can see here:

When I install gitlab-runner from this list, I have a message error like
"Something went wrong while installing Gitlab Runner
Operation failed. Check pod logs for install-runner for more details"
So when I check the logs, I have this:

The 2 last lines there is an error, some answers tell that I need to change the repo with Helm command, so I do that from the Azure CLI bash in the portal, but I still have the same error, I execute the code like this :
helm repo rm stable
helm repo add stable https://charts.helm.sh/stable
And then I update, do I need to give more arguments in commands?
GitLab 13.12 (May 2021) does clearly mention:
Helm v2 support
Helm v2 was officially deprecated in November of 2020, with the
stablerepository being de-listed from the Helm Hub shortly thereafter.With the release of GitLab 14.0 (June 2021), which will include the 5.0 release of the GitLab Helm chart, Helm v2 will no longer be supported.
Users of the chart should upgrade to Helm v3 to deploy GitLab 14.0 and above.
So that is why Helm Tiller doesn't appear in the application list of Gitlab CI.
