Upgrading Kubuntu 7.04 to 7.10 fails

[Lance DeVooght]

I'm finally getting around to upgrading my Feisty system.
I do get the "Version Upgrade" option in Adept Manager, but
during the "Preparing the upgrade" phase it fails with the following error:

============
Error during update
A problem occured during the update. This is usually some sort of
network problem, please check you network connection an retry.

My network connection is fine.
I don't know why its searching fo old Feisty files while upgrading to Gutsy.

Any ideas on how to proceed with this updagrade"
