Comment 1 for bug 1916124

After some explanation of the new approach I've been able to get this working. The extra step in our process is simply to tag a branch with a pattern following the required layout and configure the recipe to use it.

I think it's fine to close out this bug, but potentially some documentation (or a link to documentation) explaining a typical workflow could be added at the point where the error is surfaced.

In our case, as an example:

git clone lp:charm-k8s-mattermost
cd charm-k8s-mattermost
git checkout -b v5.32.1-20.04
git push lp:charm-k8s-mattermost

And then update the recipe to use refs/heads/v5.32.1-20.04.
