How to restart upgrade to Feisty?

[Ari Torhamo]

Hi!

I started upgrading to Feisty from the installation disk (desktop, daily
24.1.), but got an error message of not having enough disk space. After
removing some stuff from my hard disk I'm not able to restart the
upgrade process. 

When I insert the installation disk, a nautilus window opens - as with
any data CD - and not the window which asks if I want to upgrade my
system. Reloading the disk doesn't help, neither does restarting the
machine. I'm able to boot to the desktop from the CD and start the
installation from there, but this way I'm apparently only able to do the
full installation.

I tried to do "gksu sh /cdrom/cdromupgrade", which I found from the
documentation web site, but got just "Could not find the upgrade
application archive, exiting".

Any suggestions?

Regards,
