in terminal mode

[Eva Farrell]

I am trying to a password for root, because I do not have one I have over
30 updates I need to install but it won't let me. When I open Terminal it
says
eva@E4620~$

and I try sudo apt-get update it ask for my password however when I type
it, it says it doesn't work with eva@E4620. I don't even know hat E4620 is.
Can you point me in the right direction? I need help.

Thank you
