$ snapcraft clean delete failed: The following errors occurred: instance "snapcraft-krita" does not exist An error occurred when trying to delete the instance with 'multipass': returned exit code 2. Ensure that 'multipass' is setup correctly and try again. The container didn't exist because I just had to remove multipass and reinstall it to fix another issue. Snapcraft error #2 when it tries to delete a multipass container that doesn't exist. Perhaps it should just continue anyway, given there was nothing to delete, that's not an error in my book.
