I'm using Firefox. "gedit /etc/apt/sources.list.d/google-chrome.list copied and pasted plus "Entered" in Terminal earned a very unusual reply: The box doesn't look like normal Terminal stuff. It's titled: "google-chrome.list [Read-Only] (etc/apt/sources.list.d) - gedit (at the very top of the box in grey on lighter grey) Then "google-chrome.list x" (in black on light grey) in the upper left hand corner. The uppermost text within the box is: ### THIS FILE IS AUTOMATICALLY CONFIGURED ### (in blue on white. No normal black screen.) # You may comment out this entry, but any other modifications may be lost. (in blue on white) deb http://dl.google.com/linux/chrome/deb/ stable main (in black on white) Eep. What do I do to make sure that I don't comment it out, good sir?
