One of the reasons we were enforcing this, there were people doing package updates calling a package one version and pulling the source from a completely different branch. It was making it difficult to properly name the version, look for CVEs, etc. >> Is this caused because the SRC_URI specifies a branch and the fetched >> only downloads that specific branch from upstream?

(Binutils) someone creates branch ABC. Then they remove branch ABC, and create a new branch ABC/XYZ. If you don't prune ABC, then you can't create the directory ABC to have XYZ in it. (So you can't win in this case, you HAVE to prune or your HAVE to ignore the new branch.) (This likely won't be an issue for master/main -- but it's something to be aware of.) --Mark > Cheers, > > Richard > > > >
