Hi I'm new in Linux and I need your help :)
Every time when i type sudo apt-get update it shows:
alphaog@alphaog-HP-Pavilion-DV7:~$ sudo apt-get update E: Type 'ain' is not known on line 3 in source list /etc/apt/sources.list.d/ricotz-testing-precise.list E: The list of sources could not be read.
gksu gedit /etc/apt/sources.list
and put # in front third line but it still doesn't work. Please Help! :)
