"You are running lucid but have precise sources for some reason...." Possibly/probably because the do-release-upgrade -d fails and does not complete... I think this is caused by an ldap upgrade failure: https://bugs.launchpad.net/ubuntu/+source/openldap/+bug/943664 I'm not sure what the relation is with this issue and the missing candidates issue
