I guess we need a repo administrator to change which build steps are mandatory, otherwise, we are stuck :)

@Merinorus yes, despite been a collabroator, i cant change the build step :( I think we need Jiri the owner

@bauerji Hey Jiri in order to move forward, we really need to get rid of the the build(3.7) and build(3.8) to be able to merge the code, otherwise we wont be able to merge any code as the merge pull request is grey due to pending for build3.7 and build3.8. Would be extremely nice if you could remove them!

Hey, could you please elaborate a bit on what do you think must be done by me? 🙏 Afaik the configuration of builds is defined in tests.yaml which can be changed normally by PRs. Or is there something else in the project configuration?

Hi @bauerji , I think the branch protection rules should be changed (repo settings -> Branches).

At Require status checks to pass before merging, you can require all the following status checks:

The other checks (build 3.7, build 3.8) should not be required, as from this PR the project does not have these checks anymore.

Note: the checks are the same, but their name have changed so GitHub has lost track.

@Merinorus, great, thank you for the explanation. Done!
