I was asked this today and got me wondering of the different ways a user could get help while using Ubuntu. The particular case I was asked was, how to get help about Ubuntu in Ubuntu if there is no Internet connection available.
If it were not for that, I would had said AskUbuntu and the Ubuntu forums first, followed by IRC. But since it is offline it would be good to know, all the ways a user can get help about using Ubuntu without having any online connection. Particularly when using commands, how to navigate in Ubuntu, how to use Ubuntu and get to know it. This are common questions for some students that have started with me which are:
Students that have NEVER used a computer (60+ Year old students I should mention). The plus side is that they know how a typewriter works.
Students that have never used Ubuntu before but are Windows users.
Both cases they want to learn how to use Ubuntu in a offline way, using only what help Ubuntu comes with. Of course they can also install any help packages needed before going offline forever, so installing a package not found in the default Ubuntu setup is not a problem.
The question should be treated as using the Latest official version of Ubuntu
