I'm new to Ubuntu 12.04 LTS. My problem is described below.
My terminal prompt is the $
sign only. It's not showing like kaushik-kaushik-pc -$
.
My second problem is that when I try to become the super user by sudo su
, it prompts for my password but after that, it shows Authentication Fail
.
When I'm trying to use previous commands by using the ↑ key, it prints this ^[[a
, nor does it work for the ← or → keys.
