My institute hosts ubuntu repositories and I have added them.

However, whenever I am downloading any software from synaptic/software_centre, it downloads from the main ubuntu server and not my institute's server. How do I solve this problem?

Replace the 'main server' (is there such a thing?) by the repositories from your institute. – mikewhatever Jan 10 '12 at 7:29
The drop down menu (which is 'main server' by default) does not have the option of my institute. – Pushpak Dagade Jan 10 '12 at 7:37
Hm..., then you'll have to edit the repositories file manually and replace the main ones by whatever the institute provides. The file in question is /etc/apt/sources.list. – mikewhatever Jan 10 '12 at 8:52

Go to the "software sources" > Ubuntu Software > Download From > Choose Server> look for your "institute hosts" > select and save. Let it update.

Open a terminal Ctrl+Alt+T and typesudo apt-get update
