I can not get
snapcraft 3+ working on TravisCI Xenial in any way. Last attempt failed, even given that
lxd is installed from snap.
$ snapcraft --use-lxd Using 'snapcraft.yaml': Project assets will be searched for from the 'snap' directory. The 'LXD' provider does not support having the 'lxd' or 'lxd-client' deb packages installed. To completely migrate to the LXD snap run 'lxd.migrate' and try again. The command "snapcraft --use-lxd" exited with 2.
