If the process freezes in Ubuntu Software Center or in terminal, you should kill the process manually from terminal by typing killall dpkg, if you don't kill the process it wont let you install anything, neither from software center nor from terminal.

Facing Problems While Installing Java
I know it is a bit weird to ask this question, yet in the country I am staying, China, people love to say "Good morning" to everyone every morning.

I have never been to other countries except China and I am going to study abroad in America.

Is this social etiquette the same in America and American people say "Good morning" to their roommate every day?
