Hi
it keeps asking for the log in key ring, which i do not know, very basic here. i think it is the version from 2010. if i try to install a new version or update it it asks how to open it and sends it to archive manager ?

there are two user profiles and i only need one because that person is not using it

i cannot add anythingor update the browser and it says i am using firefox 3, but if i try to install or upgrade it just dissappears. i would also like to have a music utility like mp3 rocket but i cannot download anthing

how do i chat on here ?

oh and i downloaded the new 12, but it wont open or " run " and i dont know how to do it

If it ask for a password, put in the password you made when you installed Ubuntu. You will see nothing, it will take it when you press enter.
The people answering are all over the world, so there may be gaps in time. Some one will answer your question.
Does your computer have Ubuntu only?
Does your computer have Ubuntu and Windows?
Did you use Wubi to install Ubuntu?
How did you obtain Ubuntu?
There are many things that could be causing these problems. The more information you give, the quicker the answer.
Try your password to log in key ring.
Odd about Firefox 3, I have version 18.0.1.
Study the sites given above, while waiting on answers.
I am calling it a night, talk tomorrow.

This should be the sentence after ( it will take it when you press enter ) Copy and past results back here. Sorry sleepy.

What is the output of:

sudo apt-get update

Be sure to have software centre closed and not updates running
