Hi -
I keep running into problems caused by stale installations from the AUR, such as upgraded, ABI-incompatible dependencies or Python packages still installed under /usr/lib/python3.5/ where they are no longer found since the move to python3.6.
My understanding is that in such situations, the affected packages should bump pkgrel to force rebuild and reinstall, even if the source and the rest of the PKGBUILD remain unchanged.
Is this understanding correct? If so, can this be clarified in places such as [1][2] where people cannot miss it?
Confronted with this issue, some maintainers advise their users to just rebuild by hand, but that defeats part of the purpose of package management systems. I don't want to have to debug weird run-time errors one by one, trace the problem to this trivial issue, and then solve each of them by manual rebuild.

Hi Justus, in my opinion, pkgrel is to be bumped when something with regard to the package changes, not for the sake of rebuild only. Keeping track of rebuilds is the users task, you could e.g. after a python update go through all remaining files in the old versions folder and initiate a rebuild of the corresponding packages. This is easily scriptable and should be regarded as usual update hygiene like ocassionally checking /var/cache/pacman and other tasks. Arch is not about fully automating everything and hiding the internal workings from the user. About the debugging: when a major update happens, you are usually informed about the necessary actions in the pacman output. Paying attention to that is not optional in Arch. best Georg
