I hope someone can help me here.
I want to upgrade my maverick distribution to Natty.
But when i start i get only
"Sorry - Dist Upgrade Fetcher
Could not download the release notes Please check your internet connection."

But my internet connection works fine.

When i click on ok i get the errorcode 253.

I already test to change my sourcelist manualy, but this helps not.

Did someone have a idear?

Hi nerd,

you should first try and see if someone reported this bug in Kubuntu, it may be distribution specific. Here's a starting point:
