That is bug #412508. The file is /usr/share/gnupg/options.skel in
Debian. You can copy it yourself and adjust the permissions:

cp -i /usr/share/gnupg/options.skel ~/.gnupg/gpg.conf
chmod 600 ~/.gnupg/gpg.conf

Then you can look though the file and activate/change settings as
desired. (Almost all of it is commented out by default.) You can also
delete the first three lines; see the remark in the first line.

I just created my own "dave" and tried the same thing. I could
immediately download the key even though I got the same message about
options.skel. I think your problem is a network issue. I have sometimes
had similar trouble with various keyservers even though my network
connection seemed completely fine otherwise. These problems were always
temporary and went away without me doing anything.

I would not spend too much energy on keyring.debian.org. Downloading
keys from there is just as vulnerable to a man-in-the-middle attack as
is downloading from any other keyserver. Just find a reliable keyserver
close to you and use that one. If everything else fails then you can use
db.debian.org for manual key retrieval.

[ snip: hkp://subkeys.pgp.net works better, but not 100%. This might
  happen because it uses round robin DNS to connect you to a different
  keyserver every time. ]

Strange that gpg looks for a specific key ID in that case.

That is a quick thing to try, but I don't think this will help (see
