gnome-calculator's upstream CI builds a snap using the snapcore/snapcraft docker image. I'd like to switch it to use core18 but I don't see an easy way to update the CI to do that kind of build. Could you look into creating a docker image that already has multipass ready to go to build with the core18 base?
