Ubuntu – PkgProblemResolver error when running Package Manager and updating 12.04


Ubuntu 12.04 (Original Ubuntu version was 8.xx)

I have a message on the top bar that an error occurred and to run Package Manager.

I received the following message after running package manager:

E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages

I ran:

sudo apt-get update && sudo apt-get upgrade

The following packages have been kept back:

evolution-common evolution-indicator evolution-plugins libnspr4 libnspr4:i386 libnspr4-0d
0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.

Newbie not sure what to do next.

I solved a problem involving a subset of the packages mentioned by the OP as follows:

sudo apt-get -f install
sudo apt-get remove evolution-plugins
sudo apt-get upgrade
sudo apt-get dist-upgrade

Note sure if all of these steps were essential...
