It seems that either corosync should be updated to version 3.0.0, or the corosync-qdevice binaries should be deleted from disco-release (so that the newest version of those packages will fall back to what's provided from the older 'corosync' source package, i.e. version 2.4.4-3).
There were 3 'corosync' builds that were version 3 in disco-proposed, but none ever made it out of -proposed: /launchpad. net/ubuntu/ disco/+ source/ corosync

There were more builds for corosync-qdevice, and unfortunately those did make it into disco-release: /launchpad. net/ubuntu/ disco/+ source/ corosync- qdevice
