MarsSeed [1] filed a deletion request for mutter-ubuntu [2]: Unmaintained and unneeded package. Submitted on 2022-07-28 and never updated. Nothing consumes this, and it also does not depend on the other '-ubuntu' variant packages from AUR (all of which are unmaintained btw, and none of them correspond anymore to Ubuntu's current latest stable version). There are no comments. I think it is better to delete this. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/mutter-ubuntu/
