I managed to resolve this with "aptitude dist-upgrade" by rejecting its first solution (removing metacity etc) and accepting the second one which removed among other things libmetacity-private0 and installed libmetacity-private1. Apparently this was a result of earlier partial updates.
I can now confirm that updates succeed without errors. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1351480 Title: Compiz in utopic is older than in Trusty-updates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1351480/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
