Interesting. It works perfectly here and just lists off the names of
my PPAs.

Ah, yes. Okay, here's an updated version of it that's horrendously
long and probably badly coded, but works at my end (replace XXXX
with your source name):

apt-cache policy $(awk '$1 == "Package:" { print
$2 }' /var/lib/apt/lists/repo.XXXX*Packages) | grep -v
"Installed: (none)" -| grep -i "Installed: " -B1 | grep ':$'| sed
's/.$//' | sort -u

It seems solid to me.
