Using the AUR on Manjaro is a risk because they hold packages in the Manjaro repos back compared to Arch. So `libfoobar` might be at 1.2 in the arch repos and required by an AUR package but it's only 1.1 in the Manjaro repo which will lead to broken packages. If you're going to use the AUR, use Arch basically.
