Diskless ubuntu upgrades

10 May 2011 on Ubuntu, Linux

To upgrade ubuntu off line or to reduce the amount of duplicate data downloaded when upgrading multiple ubuntu machines download the alternate install cd iso, mount it and do the upgrade as if you’d burnt the cd

1. Download alt cd iso http://ftp.citylink.co.nz/ubuntu-releases/11.04/

2. Mount the iso to /media/iso

    sudo mkdir /media/iso
    sudo mount ~/Downloads/ubuntu-11.04-alternate-i386.iso /media/iso -t iso9660 -o loop
   

3. Run the CDROM upgrade

    gksu /media/iso/cdromupgrade
