[Bug 884152] Re: Error: Marking the upgrade (from 11.04 to 11.10) - unresolved package dependencies

[Cobalt]

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.
