This runner image has been retired and can't be used by a GitHub Actions workflow job any more.

This is a scheduled Ubuntu 20.04 retirement. Ubuntu 20.04 LTS runner will be removed on 2025-04-15. For more details, see https://github.com/actions/runner-images/issues/11101

The implications of this are that any Elixir & OTP pairs which used ubuntu-20.04 as the runner image will break as the erlef/setup-beam action uses Hex.pm's OTP builds as the source of available builds. This means that OTP versions 20.x - 24.1 inclusive aren't available for download and installation.

I'll see if I can find a replacement image or another approach which enables keeping these older OTP versions in the build matrix.

No luck in finding an immediate replacement for this deprecated image. However, I have successfully tested that OTP versions built for Ubuntu 20.04 work fine on Ubuntu 22.04. I plan to propose that Hex.pm's builder be extended to account for these deprecations of GitHub's ubuntu-20.04 runner image.

I ended up resolving this problem by creating a similar job in 71212eb and slicing the parts of the build matrix which depend on Ubuntu 20.04 in a container instead. It will make the workflow definition a little more cumbersome to maintain but the older Elixir & OTP pairs are unlikely to change.
