[Fabio Marconi]

Hello
In a fully updated Oneiric insert a usb key with 12.04 created with usb-creator.

-Expected that it notice that the upgrade volume is inserted and ask what to do as happens with the DVD

-instead nothing happens, just mount the volume and no more

This has nothing to do with a USB stick. It is because of the content of the CD/DVD/USB.

the bug is in the update-notifier data/apt-cdrom-check script
* it works with the DVD
* it works with ubuntu-11.10-alternate-amd64.iso
* it doesn't wok with ubuntu-11.10-desktop-amd64.iso

that is because the script returns 0 because there is no ./cdromupgrade file and not ./ubuntu directory on the normal ubutnu disk.

Of course the script is easy to fix, to return another value on such a CD, but I think without a ./cdromupgrade file, an upgrade from CD/USB stick is not possible.

I think this cannot be fixed? Or current Ubuntu CDs have these files? Maybe one of the developers can give advice.

Correct. Upgrading from desktop images is not supported; only upgrading from alternate CDs.
