When I run “sudo snapcraft cleanbuild”, the snap would be compiled for a decent while. For reasons unknown to me, it fails almost on the first step now, and I am unaware of having done anything that could have caused this. Nevertheless, I am getting the following message:
Creating snapcraft-merely-fast-raptor
error: Failed container creation:

Does anybody know what could have happened to cause this and what an appropriate solution would be?
