I'm running an upgrade from Maverick to Natty from a mounted 'alternate' ISO, but it's current status is "Fetching file 1444 of 1703 at 55.1 kB/s". I'm pretty sure it's trying to use the network for the "Getting new packages" phase. How can I make sure it uses only the ISO, and not the network? Disconnecting the network (or keeping it disconnected the entire time) just results in stalling (waiting, not freezing) during the "Getting new packages" phase.

I've followed the instructions on the Ubuntu Wiki for upgrading using the Alternate CD ISO mounted as a drive. Also, I selected "No" to the question about updating packages during the upgrade.

If this is a bug, please give a link with the bug number or tell me that I should file a bug.

I also had this problem. My solution was to uncheck all software repositories, then the upgrade from cd worked.

Using the Alternative CD, and not unplugging the Ethernet (before) boot, does NOT behave the same as answering: NO.

Have you tried, with the network cable umplugged?

Following the upgrade instructions on the Ubuntu Wiki:

Burn the ISO to a CD and insert it in your computer OR mount the ISO using:

sudo mount -o loop ubuntu-11.04-alternate-amd64.iso /media/cdrom

When done, run the upgrade application from the CD:

gksu /media/cdrom/cdromupgrade

Follow the instructions, when askes whether you want to download updates from the internet, choose No.

The alternate cd does not have everything on it. I recently did this using the dvd image and it seemed to only download one or two things ( I didn't answer no to the question ). Maybe you have a bunch of packages installed that are not on the alternate cd so it has no choice but to download them?
