Comment 78 for bug 2034619

Maybe this problem shouldn't be posted here but I can't remove the ppa version. "sudo apt install -t mantic-proposed mutter" installed the new mutter from the ubuntu repos, but the other packages are still "local" from the ppa (I think). Anyway, it's working. Would still want the ubuntu versions though. :)

edit:
I had deactivated Mario's ppa before running ppa-purge which is why it didn't find the files list.

Not sure which version I'm using. It's not mutter (45.0-3ubuntu3.1) as the previous poster.
