Lubuntu PAE-Problem

Installing Lubuntu 12.10++ on devices using Pentium M processors may fail due to "missing PAE support" of these CPUs. In fact, the PAE feature is built-in in these CPUs (as in all Intel CPUs starting from Pentium Pro processors) but isn't reported correctly by the CPU in CPU flags, so Lubuntu refuses to install on that systems.

More information on this is available on prof7bit's site, for me it is important to keep this info handy because I don't want to search the net for this code every time I install a Lubuntu system. Since Microsoft will cease support for Windows XP in 2014 I'll have to update a whole lot of systems of friends and relatives to Lubuntu and I'll need this peace of know-how one or another time during the next time ... :-)

First install Lubuntu 12.04, then install the fake-pae package:

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

Now update Lubuntu 12.04 to 12.10 by running

sudo do-release-upgrade

and maybe a second time in 12.10 if you want to upgrade to 13.04.
