I’ve got a commit for Mojo’s snapcraft.yaml to add base:core, so that it uses Multipass by default. The first time I run snapcraft this builds fine, but subsequent attempts (after changing something in the upstream source) fail with:

Failed to run '/root/stage/usr/bin/python2 -m pip download --disable-pip-version-check --dest /root/parts/mojo/python-packages .': Exited with code 1.
Run the same command again with --debug to shell into the environment if you wish to introspect this failure.
An error occurred when trying to execute 'sudo -i env SNAPCRAFT_HAS_TTY=True snapcraft snap' with 'multipass': returned exit code 2.
I did find bug #1768233 which is similar but the workarounds listed by Sergio there don’t work for me.
Any hints appreciated. You can find it all in bzr branch lp:~laney/mojo/snap-base. Steps to reproduce:
$ snapcraft
[ ..., works ]
$ vim mojo/cli.py # make some change
$ snapcraft
[ ... breaks, as above ]
