It looks like publishing collections through Zuul (Zuul) is currently broken. The publishing step tries to install ansible-core devel in a Python 3.11 venv, which no longer works. There seems to be a PR that might fix this (Remove temporary work around to publish a collection by GomathiselviS · Pull Request #602 · ansible/zuul-config · GitHub), but it hasn’t been merged yet.
I think now might be the time to move from Zuul to GitHub Action. It’s something we are looking at doing as part of simplifying ISV Partners repos being published to Galaxy & Hub
That would be nice, but I’m not sure how this can be done in a safe way. IIRC in Galaxy you can only have a token for the whole community namespace, and not one for individual collections. If that’s still the case, using GHA sounds pretty dangerous.
The PR has been merged, and releasing works again! Thanks 
Maybe start a new thread on this? Or do we already have and I’ve overlooked it?
