Title:
security.ubuntu.com (2001:67c:1562::XXX) not reachable
Status in update-manager package in Ubuntu:
Confirmed
Bug description:
I know this is not a bug in the software, but in the network
connection of some of the security.ubuntu.com servers via IPv6. Which
leads to the problem that no software update is possible without
changes in the /etc/gai.conf to prefer IPv4. It resolves to following
IP addresses:
$ host security.ubuntu.com
security.ubuntu.com has address 91.189.91.13
security.ubuntu.com has address 91.189.91.14
security.ubuntu.com has address 91.189.91.15
security.ubuntu.com has address 91.189.91.23
security.ubuntu.com has address 91.189.91.24
security.ubuntu.com has address 91.189.92.200
security.ubuntu.com has address 91.189.92.201
security.ubuntu.com has address 91.189.88.149
security.ubuntu.com has IPv6 address 2001:67c:1562::15
security.ubuntu.com has IPv6 address 2001:67c:1562::17
security.ubuntu.com has IPv6 address 2001:67c:1360:8c01::19
security.ubuntu.com has IPv6 address 2001:67c:1562::13
security.ubuntu.com has IPv6 address 2001:67c:1562::16
security.ubuntu.com has IPv6 address 2001:67c:1360:8c01::18
security.ubuntu.com has IPv6 address 2001:67c:1562::14
All IPv6 addresses that start with 2001:67c:1562:: are not reachable
from some providers. e.g. Hurricane Electric's, but the error seems to
be on the server site. The 2001:67c:1360:8c01 ones work.
An MTR from inside HE's network shows it gets into XO's network, then
dies where it hands off to Internap who gets the routes from
Occaid/TowardEX, or it used to. Now going via Telia, it still dies
inside Internap's network. Not an HE issue - please inform your
networks guys. Thx.
