I can confirm this bug in a way. Backgrund info: I upgraded from Gutsy to the RC of Heron (or at least it said "This is a release candidate" before performing the upgrade though the RC had not officially been released yet due to the delay).
So far updating always worked fine, but when I opened the update manager a few hours ago a dialog popped up and told me that not all updates could be installed and offered to perform a partial upgrade, which I did. I started the update manager again after that to see whether the missing updates could be performed now. I saw that only one update was left: update-manager-core and that was unselected. Nevertheless the "partial upgrade" dialog popped up once more, I accepted again and a few seconds later the updater noticed that nothing was left to update. When I canceled the update dialogs, the update-manager-core update was grayed out and could not be selected. I decided to go for the command line and used the apt-get commands autoremove, autoclean, update and install but the update-manager-core did not get installed ths way either. I decided to remove it and ubuntu- desktop, update-notifier and update-manager got removed with it because of the dependencies. The interesting thing though is that now update- manager was found to be not installable, while i could indeed install update-manager-core again. -- missing update-manager in hardy heron https://bugs.launchpad.net/bugs/185906 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
