Why did I a get a Bad Archive Mirror?

When I was installing Ubuntu non physical address extension (pae) 12.04 onto my IBM T42 type 2378, I got a bad archive mirror.

I live in the USA. I selected the default archive mirror us.ubuntu.com. I also got this message

to get more info check /var/log/sys/og or virtual console 4.

I do not know what that means and where to go to get the report.

Official Ubuntu archive for USA is located at address: us.archive.ubuntu.com

You must edit your sources.list and change us.ubuntu.com for us.archive.ubuntu.com, you can do this with the terminal:

sudo sed -i '/us\.u/us.archive.u/g' /etc/apt/sources.list

This will correct your mirror.
