Install Ubuntu 12.10 or 13.04 on non pae CPU like Intel Pentium M

Ubuntu 12.10 and 13.04 do not support non pae CPUs, but all Intel Pentium M cpus should work fine with ubuntu latest kernel if memory is below 2Gb even without the PAE feature, at least that is my understanding.

Install the fake-pae package

sudo add-apt-repository  ppa:prof7bit/fake-pae
sudo apt-get install fake-pae

Intall ubuntu next release, do this in each cycle:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

sudo apt-get clean
sudo apt-get autoclean

sudo do-release-upgrade -d

I upgrade my old laptop a vaio vgn-a190 from 11.04 to 11.10 to 12.04 to 12.10 to 13.04.

The only problem with this method is that you need to use the upgrade method instead of the live CD, and it takes a long time for each release upgrade.

In case the do-release-upgrade command reports some packages errors, use the following commands before upgrading to the next release

sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get autoremove
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get install ubuntu-desktop

This Post was created using the vaio on Ubuntu 12.10 while is updating to raring.


  1. You can use Lubuntu-fake-PAE to avoid upgrading in several steps

  2. Hi Iafa, Thank you for this nice information. However I need to ask, will this fake-PAE method would work if I am installing Ubuntu 12.04 from start? Means if I am installing with boot-able USB?

    So what I have to do in this case?

    Thank You!

  3. Lubuntu fake-PAE can use a USB boot drive with grub2, which works because there is no check for the PAE flag like in syslinux. You can add any new Ubuntu desktop iso file and boot it with the 'grub-n-iso' or 'grub-n-iso-n-swap' method.

  4. I prefer the light-weight Ubuntu flavours Lubuntu and Xubuntu for such old CPUs (Pentium M and Celeron M). The versions 12.10 and 13.04 are possible to run with fake-PAE.

  5. I wrote about lubuntu grub'n'iso fake pae img
    on the Peppermint 4 forums.
    Go to the NewUsers section and look for "NON-PAE SUCESSFULL INSTALL"
    you can install peppermint 4 using the lubuntu grub'n'iso ,but you cannot install most other ubuntu distros.
    it works because of the lubuntu in peppermint 4.
    mint 14 worked almost!
