This question already has an answer here:
I have read quite a few of the answers to password problems but am completely new to Ubuntu and can't figure this out.
I bought my computer (a Dell vostro) a few days ago, and I was trying to install some apps and it asks for an authentication code. I got as far as to check user account (only one, admin) and it doesn't seem to have a password.
I read a thread about setting a password but I don't know what "Windows Key" or "Terminal" are, so could someone please explain this?
