Ubuntu 9.10 (Karmic Koala) batch upgrades

I had the need to upgrade multiple pcs with Ubuntu 9.04 without downloading for every single instance all the files needed for the upgrade process to work.
You will just need to download the “alternate” Ubuntu iso (that you can find here).

Then as next step you have 2 choices, burn the cd or mount the iso file locally as below:

sudo mount -o loop ubuntu-9.10-alternate-i386.iso /media/cdrom0

Then we can run the executable “cdromupgrade” inside the root of the cdrom:

sudo /cdrom/cdromupgrade &

and then follow the normal upgrade process through the interface.
