I want to change my software sources because I don't want to update my Ubuntu from other software sources. I tried to change it from Unity dock: I typed software source and a icon appeared but when I clicked nothing happened.

And then I tried it from Update manager: I clicked on edit->source but nothing happened.

I am still able to download and install updates as well as software from Ubuntu Software Center

You could always edit it manually too. The file is at /etc/apt/sources.list . Make sure you make a backup copy of the file before you edit it so that you can go back to it if the need arises. – Nitin Venkatesh Dec 10 '11 at 13:16
i am using ubuntu 11.10 with kde-standard – paru38 Dec 10 '11 at 13:17
The apt's sources.list file is always in the same place in every flavour of Ubuntu. So I am pretty sure the file is at /etc/apt/sources.list – Nitin Venkatesh Dec 10 '11 at 13:20
i am able to open file list from command line 'sudo gedit /etc/apt/sources.list' but how to know which source is offering me other software sources or unsupported sources – paru38 Dec 10 '11 at 13:21

you can open your software from

gksudo gedit /etc/apt/sources.list

here you will find your software sources

and you can chose your software sources you need every source has its description which is followed by #

you can delete the other software sources

You could give this terminal command a try:

Under GNOME/Unity

gksudo software-properties-gtk

Under KDE

kdesudo software-properties-kde

Dont see any reason for the downvote here, this actually might have worked fine. – Bruno Pereira Dec 12 '11 at 23:48
