I finally managed to reach to Ubuntu after many unfair-unsolved errors and boot errors as well..
Now another unfair issue detected. I made an user account with password, great, I downloaded steam, I double click it, authenicator shows up but when I type something, it doesnt show on authenticator!!!
It wants a password for the user name account I use to let steam download packages, but when I type anything, it does not show on authenticator!It does do nothing but to say error that I typed nothing. I even deleted password of my username account and it still shows up. What the h!!! is this problem? Its even annoying than Justin Bieber!!
Authenticator is my next nightmare...How do I solve it?
