I have a virtual private server that runs the out-of-date Ubuntu 10.10. I'd like to upgrade to 12.04 LTS.

Currently apt doesn't work on this box, and the command do-release-upgrade is not found.

There is nothing on this VPS that I need to save, I'm OK with wiping it clean and installing 12.04, but I don't know how to do that when my only access is to a terminal remotely.

I'm not sure how would one go about wiping and reinstalling Ubuntu remotely, but you could try the following to upgrade remotely, without apt and do-release-upgrade.

  1. Download the "Alternate CD" for 12.04.3 LTS server edition using:

    For 64-bit:

    wget http://releases.ubuntu.com/precise/ubuntu-12.04.3-alternate-amd64.iso

    For 32-bit:

    wget http://releases.ubuntu.com/precise/ubuntu-12.04.3-alternate-i386.iso

  2. Mount it to /media/cdrom using:

    sudo mount -o loop ubuntu-12.04.3-alternate-amd64.iso /media/cdrom

  3. Run the following command to start the upgrade:

    sh /media/cdrom/cdromupgrade

    Or, if you're not root:

    gksu "sh '/media/cdrom/cdromupgrade'"

Note 1: I don't know if it's possible to directly upgrade from 10.10 to 12.04. I think you'll need to go through the releases in between, one by one.

Note 2: I haven't tried the above steps before, so I'm not sure if it will work. But according to this: PreciseUpgrade, it should. The steps there indicate to mount the .iso file to "the exact name of the CD", but I'm not sure what the exact name of the CD is on 10.10.
