ubuntu-minimal cannot be found - herd 4 upgrade fails

[AmazingRando]

Binary package hint: update-manager

Attempting to upgrade using the herd 4 desktop CD iso and running cdromupgrade.sh at the step "Modifying software channels" I get the message:

"After your package information was updated the essential package 'ubuntu-minimal' can not be found anymore.
This indicates a serious error, please report this bug against the 'update-manager' package and include the files in /var/log/dist-upgrade/ in the bugreport."

Running from command line gives the error after exit of "WARNING: Failed to read mirror file"

term.log was empty so it could not uploaded

Note that the iso is mounted, not a physical CD. also note that I've tried it both double-clicking the cdromupgrade and running it from the terminal using the absolute path. Also, I have tried running as root (sudo) and when I start the install, I choose not to use the network.

Thanks for your bugreport.

The problem here is that the desktop CD should not contain a upgrade script as it does only contain a very limited pacakge selection.

I will attach a patch.

Cheers,
 Michael

This patch against debian-cd should fix the problem. But please test first :)

Moving to ubuntu-cdimage product.

Fixed, thanks. I used CDIMAGE_INSTALL_BASE instead as I felt that was slightly more appropriate, but otherwise the patch is the same.

Marking as invalid on update-manager, as the bug was fixed in an other package.
