Indeed, after removing the package you suggested, the error icon disappeared from the top panel. After rebooting, I was able to install important updates using the graphic update manager. However, after launching this update manager once again - even after rebooting - I am shown recommended updates (see attachment), but the Install Updates button is grayed out.
There are no error messages in the (graphic) update manager, but I had previously gotten warnings about other held packages (see earlier comments). In 11.04, I used evolution, which I have not been able to use since the upgrade to 11.10. sudo apt-get install evolution gives the following error. The following packages have unmet dependencies: evolution : Depends: evolution-common (= 3.2.1-0ubuntu1) but 2.32.2-0ubuntu7 is to be installed E: Unable to correct problems, you have held broken packages. Should I try uninstalling the packages that are held back? There are three of them now. evolution-common evolution-plugins libgl1-mesa-glx Should I then attempt to install evolution again? Thank you very much. ** Attachment added: "UpdateManager.png" https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/884152/+attachment/2636949/+files/UpdateManager.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/884152 Title: Error: Marking the upgrade (from 11.04 to 11.10) - unresolved package dependencies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/884152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
