When you see the message it means you need to type this in a terminal:
It will bring up the man pages for that item.
9/10 times man pages confuse me. So I use google to find most of my answers.
But to make things easier for you, all you have to do is open a terminal and su to root (type su, press enter, type in the root password, press enter) then open the sources.list file in your favorite text editor (mine is nano):
Then change all "sarge" to "etch" and save the file (for nano press CTRL+X to save).
Once the file has been saved with the new sources, you have to update the package lists.
If it errors, you have a typo or error in your sources.list file.
Once it successfully updates then you need to upgrade to etch with the dist-upgrade.
If this fails for whatever reason, run this command:
Then try dist-upgrade again until everything is finally upgraded.
