I ordered a new computer with Windows 8 to test before rolling out. It arrived with Ubuntu 12.04. Rather then just send it back, I decided to check it out first as I think the system is probably much better than the MS options. However, try as I might, I cannot get a PPA set up. I'm trying to install Pinta-Paint but can't find the line to copy into the software centre. Please could someone point me in the right direction.
