Comment 1 for bug 1741474

I've posted some findings in the forum topic: https://forum.snapcraft.io/t/on-arch-snaps-show-broken-after-switch-from-snapd-to-snapd-git/3427

Bottom line is, snapd and snapd-git packages from Manjaro's repo do not perform a proper cleanup on removal. Manjaro carries a snapd-git package in their own repositories and it's not the same package as snapd-git from AUR. To get it fixed, we'll need to work with Manjaro to have their packages updated.
