hardy apt-file error

[Donald Raikes]

Hello,

I installed hardy last night, and in my excitement, I edited
the /etc/apt/sources.lst file because I cannot use the software sources
applet with orca.

Now when I try to run apt-file update, I get an error saying that
apt-file cannot read one of the repository files headers.

Is there somewhere I can get a default hardy /etc/apt/sources.lst file
to go back to ground 0?
