I ran across a similar problem today and found that temorarily
commenting out the IPV6 lines in /etc/host (see below) resolved the problem.
# The following lines are desirable for IPv6 capable hosts
# ::1 ip6-localhost ip6-loopback
# fe00::0 ip6-localnet
# ff00::0 ip6-mcastprefix
# ff02::1 ip6-allnodes
# ff02::2 ip6-allrouters
# ff02::3 ip6-allhosts
This was occuring on a laptop that I recently installed a very old
PCMCIA Kinston 10Mb ethernet adaptor. So my guess is that it is the
adaptor that is causing the problem as I don't have any such problems on
my other systems.
Note: normally I find that it is the archive.ubuntu.com etc., server
that is the problem, but in this case I suspect it's the NIC not being
able to handle IPV6 packets. For instance, one of the servers that I
normally use also returns an IPV6 address:
~$ host ftp.usf.edu
ftp.usf.edu has address 131.247.254.5
ftp.usf.edu has IPv6 address 2620:0:c30:11fe::2
us.archive.ubuntu.com does not. But it does have multiple dns pointer IP's:
~$ host us.archive.ubuntu.com
us.archive.ubuntu.com has address 91.189.88.46
us.archive.ubuntu.com has address 91.189.88.31
us.archive.ubuntu.com has address 91.189.88.45
:~$ host 91.189.88.46
46.88.189.91.in-addr.arpa domain name pointer lithium.canonical.com.
~$ host 91.189.88.31
31.88.189.91.in-addr.arpa domain name pointer leningradskaya.canonical.com.
~$ host 91.189.88.45
45.88.189.91.in-addr.arpa domain name pointer prat.canonical.com.
and that may cause dns problems if you hit a dns cache that hasn't been
updated.
