After adding a repository I see this problem

[sinaphysics]

I want to upgrade to gnome 3.6 so I add a repository and try it but when I want to use
sudo apt-get update

I receive this error


E: Type 'ain' is not known on line 1 in source list /etc/apt/sources.list.d/gnome3-team-gnome3-precise.list
E: The list of sources could not be read.


How can I fix this problem ?

sounds like the line is malformed, what does it say?


cat /etc/apt/sources.list.d/gnome3-team-gnome3-precise.list

I fix it myself. I'm using for 2 year Ubuntu but always I feel amateur in ubuntu but I fix it. Maybe it's too easy.

Sudo rm /etc/apt/sources.list.d/gnome3-team-gnome3-precise.listand then run


sudo apt-get update

thank you jerome1232 (http://ubuntuforums.org/member.php?u=453029). Is it possible to explain what "cat" do ?

it's a command used to concatenate files, meaning join them together, however it's also frequently used to simply read a files contents to standard output (your terminal).

That's all my command was doing, was reading the contents of the troublesome repository file and displaying them in your terminal.
