Download snap "snapd" (9279) from channel "stable" (received an unexpected http response code (503) when trying to download https://api.snapcraft.io/api/v1/snaps/download/PMrrV4ml8uWuEUDBT8dSGnKUYbevVhc4_9279.snap) that happened during do-release-upgrade from 18.04 to 20.04, but the consequence is that the entire upgrade is now considered to be failed and I have to pick up the pieces manually.
