[ SOLVED ] upgrade from 10.04 to 10.10 problem, Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade
While I updated ubuntu from 10.04 to 10.10, I got a following error. Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade: E:Unable to correct problems, you have held broken packages. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bug report. I have made sure all packages are up to date and Synaptic does not indicate that any packages are broken. or E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. The solution is just remove xserver-xorg-video-nouveau package and everything works fine. ref : Seb Harrington
