Update 18 november: I've updated several repositories to use ubuntu-24.04 instead of 20.04 or 22.04. In particular, ejabberd in d3baacd7 updates ubuntu to 24.04 (and use containers in Runtime) for all workflows and jobs except CI.
Ubuntu runners
GitHub Actions provides several runners where we can run our workflows:
Now that GitHub is considering ubuntu-24.04 as ubuntu-latest, it is expected that in the near future ubuntu-20.04 will be marked as obsolete. Once that time arrives, we will have to upgrade our actions from ubuntu-20.04 to ubuntu-22.04 or higher.
Erlang/OTP install methods
When the runner doesn't include Erlang/OTP (for example ubuntu-22.0.4 and higher), or we want to use a specific erlang version, our workflows use two alternative methods to install Erlang, depending on the requirements of the workflow:
A) Erlang Docker container, suitable for simple tasks (running rebar3/mix, compiling, testing dialyzer, starting/stopping ejabberd)
As ejabberd supports from Erlang/OTP 20.0 up, for complex tests like ejabberd's ci and runtime, we need to use ubuntu-20.04. In ubuntu-22.04 there's no way to install Erlang/OTP older than 24.2 to use it for complex tests.
We support two latest LTS Ubuntu versions, so Ubuntu 22 will still be available in near future.
In the future when ubuntu-20.04 runner is deleted and we are forced to use ubuntu-22.04, I expect that there will be no way to test ejabberd with Erlang/OTP lower than 24.2. When that time arrives, we may have to raise the Erlang/OTP requirement in ejabberd to 24.2.

erlef/setup-beamaction is suitable for complex tasks (setting up databases and run ejabberd CI), but in ubuntu-22.04 the lower erlang supported is 24.2.Our Ubuntu usage
This is a summary of what we are using right now:
As ejabberd supports from Erlang/OTP 20.0 up, for complex tests like ejabberd's ci and runtime, we need to use ubuntu-20.04. In ubuntu-22.04 there's no way to install Erlang/OTP older than 24.2 to use it for complex tests.
What to expect in the future
As mentioned in https://github.com/actions/runner-images/issues/10636
In the future when ubuntu-20.04 runner is deleted and we are forced to use ubuntu-22.04, I expect that there will be no way to test ejabberd with Erlang/OTP lower than 24.2. When that time arrives, we may have to raise the Erlang/OTP requirement in ejabberd to 24.2.
