upgrading to 9.10

[Osman Kemal Kadiroglu]

Hi,

I have tried to upgrade AMD64 computer from 9.06 to 9.10. I used o get 
the following message when I used apt-get upgrade command.

oyo at oyo-kubuntu:~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages have been kept back:
 landscape-common linux-generic linux-headers-generic 
linux-image-generic linux-restricted-modules-generic mencoder mplayer 
swiftfox-athlon64
0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded.

Now when I used KPackageKit while calculating the changes I got the 
following message and could not upgrade.

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generated breaks, this may be 
caused by held 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.

What am I suppose to do? Thanks for your help. Best Regards
