note that during bionic->cosmic upgrade test, I noted that the lxd package upgrade fails quite loudly without snapstore access; and it claims lxd will be unusable after the upgrade. Since that is a separate issue from this bug, I opened bug 1834501 to track that, and I'll continue to verify the fix for this after removing the lxd package from the testbed.
