I have messed up the PPA and now I do not know how to revert the sources.list to its original form.

Thank you!

Check that you don't have any elementary OS repositories launching Software & Updates from Slingshot or terminal:


If you have checked it, open a terminal and execute:

sudo add-apt-repository ppa:elementary-os/os-patches 
sudo add-apt-repository ppa:elementary-os/stable 
sudo apt-get update 

Try to check now for new updates with:

sudo apt-get dist-upgrade 

That's all.
