I believe you can just remove your layers and update, but if you've got stuff backed up, reinstalling probably works. Maybe someone else has a better suggestion
@KyleGospo sorry for the stupid question but i want to help a friend of mine install bazzite on his ally since there's an image for it now, can i just tell him to download the 2.02 release from github and will it be included in that?
I can't remember if it was you who posted the image, but using rpm-ostree install adds layers(?) on the image. If you haven't done that, then I think it's irrelevant.
