UPDATED: more on apt-spy

Well, If I had just read the file it would have told me that "the following list can always be found at" debian.org ... So the mirrors.txt that comes with the latest version of apt-spy is the one you want to use, but you want to use the older version of apt-spy as follows:

# cp -p /var/lib/apt-spy/mirrors.txt .
# apt-get --purge remove apt-spy
# wget -c http://ftp.debian.org/debian/pool/main/a/apt-spy/apt-spy_3.1-13_i386.deb
# dpkg -i apt-spy_3.1-13_i386.deb
# cp -p ./mirrors.txt /var/lib/apt-spy/.
# echo "apt-spy hold" | dpkg --set-selections

And the newest list of mirrors only generated 59 errors, which
is far fewer than the one from 3.1-13 will give you. So again, you'll still probably want to use the -f ls-lR.gz something like this:

# apt-spy -d unstable -f ls-lR.gz -o ./output.sources.txt -w outputFile.txt -n 20

Following up on my previous notes about errors with apt-spy ...

Here is a recent version of mirrors.txt with all of the erroring sites meticulously removed as of today.

And here is a sources.list that apt-spy has generated for me.

If you are like me you feel better when you have a list of mirrors that does not waste time generating a bunch of errors and time outs, even if it's only good for a day or so before the errors start to creep back in.
