You haven't quoted the complete error message, so i can't say what
is wrong exactly, but i am sure that it is unrelated to apt.
apt bails out this message if getaddrinfo() in connect.cc fails with
a "strange" error - APT complains about "not so strange" errors differently
(which are EAI_NONAME, EAI_SERVICE and EAI_AGAIN).

All others will lead to this message. The number in brackets at the end is
here the integer value of this error - you can look up the problem yourself
or create a boilerplate program which call gai_strerror() with this
integer value.
If you want to can also recompile APT with the following patch applied
(which will most likely included in upcoming apt uploads).
See man 3 getaddrinfo and /usr/include/netdb.h for details.

Also of interest for you is maybe this email on debian-devel
http://lists.debian.org/debian-devel/2009/10/msg00445.html
(I have cc'ed Dominic Hargreaves to inform him about this bugreport/thread,
 but i don't sent this mail to the list as my answer is rather apt-centric
 and has few to no value for "normal" debian-devel)


Best regards / Mit freundlichen Grüßen,

David "DonKult" Kalnischkies


P.S.: Please don't forget to reassign the bug to a better fitting package,
if you isolate the cause. I have not closed it just to save you from the
hassle of reopening it. ;)
