PPA weirdness

[David Robert Lewis (ethnopunk)]

I can't see the file in /var/lib/apt/lists/

but getting this message

E: Could not open file 
/var/lib/apt/lists/ppa.launchpad.net_capitanterrex_ubuntu_dists_karmic_main_source_Sources 
- open (2: No such file or directory)

Is this a bad database entry?
