In my work I need to study about FOSSology. This tool supports only in Linux. So i have installed Ubuntu version 12.10 Quantal. Through net i have come to know Ubuntu has inbuilt postgreSQL application. But when i installed i don't know how to see whether it is already installed. Could you please help me in solving this issue. It's high priority and i have short time to finish my work.
I have downloaded manually and while install after executing this command sudo dpkg -i File.dep i am getting error message saying that This need root user privileges. PLease help me.
