My neighbour forgot his admin password and wants to install a printer -.-
Now, I announced there is an easy way to do it in Linux... I got an image somewhere of Ubuntu 12.04.

Some guide is talking about the repository being multiverse... so added the name to /etc/apt/source.list, apt-get update...

after I couldn't find it and ~45min later!!!!!

I checked this site:
program: chntpw
it claims it is in the repository universe... but I had already a multiverse!

Well, added 'universe' and it is installed now, but boa the official Ubuntu docu is useless with windows and clicky stuff about synaptic, which isn't even installed any more. The only thing I could find in the setting (after breaking my fingers with Unity on the touchpad) was Ubuntu Shop something...
