The current gitlab-runner package is very outdated and I see problems with jobs in my pipeline.
I'm not sure if it is related to the old version, but I think an upgrade will not hurt.
The upgrade uses the nicer way from ports to build go packages, but fetches the go.mod from the gitlab platform, as goproxy does not have it.
(If it is ok for you, I would cotmmit it together with the gitlab-ce 15.6 update.)
I saw that it also fixes security issues, if it is ok for you, I would commit it directly:
