Bug Description
Binary package hint: update-manager
I have upgraded from Edgy to Feisty (when Feisty came out). Now using the Alternate CD I have tried upgrading to Gibon, but it fails. I choose not to download additional files from the internet as I have a very slow connection. The messages that I get is as follows:
Can't install 'ubuntu-desktop'
It was impossible to install a required package. Please report this as a bug.
Could not calculate the upgrade
A unresolvable problem occurred while calculating the upgrade.
Please report this bug against the 'update-manager' package and include the files in /var/log/

me too.
I think ubuntu could not upgrade from CD without Internet connection, even if we didn't got this error.
Because some of your software packages may not be contained in the CD/DVD, so you must download them from the Internet repository during the upgrade process.
I find a way to download less packages from Internet when you upgrade to ubuntu7.10. Of course you should have a Internet connection first.
1. Run update-manager, upgrade from the Internet, after the apt source setting process (when it is downloading the package files), cancel it.
2. Upgrade from CD/DVD, you may find the problem above is resolved.
But if you have installed some packages which are not included in the alternate CD, then these packages will still be downloaded from the Internet.
It means you can get most of the packages from CD, less from Internet.
PS: I need to download more than 1300 packages during the upgrade process, 994 was from the CD, the others was downloaded from the Internet.
