Upgrade 10.04.1 -> 10-10 problem

Hi!

I am trying to update from ubuntu 10.04.1 to 10.10 using the do-release-upgrade command.

I get this error:

Code:

An unresolvable problem occurred while calculating the upgrade:
The package 'update-manager-core' is marked for removal but it is in
the removal blacklist.

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

The first two can't be correct right?
So... If the third one is true. How can I find these packages?

Or, is there any other way to upgrade to 10.10?

Have you tried following the steps here?

Yes.
I noticed that i inserted a "." in the middle of my text (now fixed) but that was exactly what I was tryring to say in my first sentance =)

My bad... I didn't realise that that was what the do-release-upgrade command ran

Hm, have you got any non-ubuntu entries in your sources.list file? (in /etc/apt)

No. I did modify it but I made a backup of the original and it was restored before I tried to do the upgrade.

And is there anything interesting in /var/log/dist-upgrade/main.log, or only error messages about the same package?
