View Full Version : [ubuntu] upgrade problem

hi geeks
I am bit stuck up as I can't upgrade from 10.04 to 10.10
when I try through a alternate cd I get a window with the following message

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~
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.

I previously upgraded to 10.04 using the same method
is this causing the problem

also I tried to upgrade thru the network but 407 error is returned
I had done all proxy settings but nothing workd
thanking u in anticipation
