View Full Version : [ubuntu] can not upgrade distribution (think I know why)

April 30th, 2010, 04:18 PM
Since 9.10 was available, I've been unable to upgrade to the next distribution. Today I actually took the time to copy down and make note of the error given.

The pop-up error is this:

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.

Speaking of held packages, I haven't updated xserver-org since 8.10. When I first upgraded to 9.04 I suffered from the driver issues since I had an old ATI card and so I followed directions to fix this (http://tan-com.com/posts/technology/fix-ubuntu-904-ati-driver-issue) by blocking xserver-org updates. Well now I've got a nice new NVIDIA card and this work around isn't necessary anymore anyway, so perhaps by reversing this, I can update finally?

I'm just not sure how to undo what was done in the tutorial.

Same here I'm unable to get the download the ubuntu 10.04. Is downloading the iso image and then reinstall the os the only option?
