Way to upgrade from precise pangolin 12.04 to alpha 1

[starbetrayer]

Hi guys,

I just wanted to share a way to upgrade from precise pangolin 12.04.
I do not recommend it for new users by any mean.

sudo sed -i 's/precise/quantal/g' /etc/apt/sources.list
sudo apt-get update && sudo apt-get dist-upgrade

This will modify the source.list file and you will be able to update to the alpha 1.

And to fix all those ppa's (most of which won't work at this point, but eventually will):

cd /etc/apt/sources.list.d
sudo rpl --dry-run -x ".list" "precise" "quantal" *

This will print a list of what the command is going to do; repeat the rpl command and rub out the --dry-run part to
do it for real.
