Upgrade to 11.04 error / failing

[solitaire]

I'm trying to upgrade my 10.10 to 11.10 (via 11.04)

But after the "setting New Software Channels" I get the following error box when upgrading to 11.04:


Could not determine 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 reportAny suggestions on where to look to fix this?
Or is it just easier to do a clean install?

"Unofficial software packages not provided by Ubuntu"

PPA's; third party software sources could be the cause.

Tried removing all PPA's and running "Computer Janitor" to remove all unofficial packages,

Still no difference!!

Still getting the same error

Looks like it's a Wipe and reinstall :(

Unless anyone else has any ideas?????

Did you run sudo dpkg --configure -a and sudo apt-get -f install to ensure all necessary packages are completely installed and configured?

Ran both commands.
Everything was installed and configured correctly!

If you run
sudo apt-get --fix-missing install
sudo apt-get -f upgrade what is the result?:

If you run
sudo apt-get --fix-missing install
sudo apt-get -f upgrade what is the result?:

Here's what I get:



bill@Ion:~$ sudo apt-get --fix-missing install

Everything looks OK!

Check your graphics driver, if you use proprietary driver, reinstall it.

Should be a good idea to report the bug as it's stated to the error message

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
