On Archlinux it is not recommended to update only one package with the package manager pacman. Let’s say I have 11 packages, and one of them is extra/firefox (true story). Updating only a pacman -S firefox could introduce problems, but installing a new single package if it wasn’t there is okay.

So my question is, could we get around this by removing and installing the same package again in one go: pacman -Rs firefox && pacman -S firefox

    IF no dependency tries to update too. Off course in that case I would stop. Without pacman -Sy, I never do that anyway, only -Syu.

    That’s all you need to know. As long as you always use pacman -Syu you will be fine. pacman -Sy is the real problem. The wiki page is pretty clear about the sequences of commands that are problematic https://wiki.archlinux.org/title/System_maintenance#Partial_upgrades_are_unsupported.

    Right? What i don’t understand is, when I uninstall with pacman -Rs firefox, delete the cached firefox package (only that file), then the system is in the same state as before I installed it. Then -S firefox should be okay, right? And it even looks up the new version.

    This isn’t correct. It won’t look up the new version. Assuming that the system was in a consistent state it will download the exact same package that you deleted. The system only ever “updates” when you run pacman -Sy. Until you use -y all packages are effectively pinned at a specific version. If the version that gets installed is different than the one you removed it probably means that you were breaking the partial update rule previously.
