Bug Description

Several Launchpad sites only support IPv4. This prevents me for instance from using on a IPv6 only host:

Reading package lists... Done
W: Failed to fetch Could not resolve ''

W: Failed to fetch Could not resolve ''

W: Some index files failed to download, they have been ignored, or old ones used instead.

Probably not, because the machine(s) in question do not have IPv6 connectivity, or it has been obscured.
Since is not a 'dumb' fileserver with a bunch of static content, there's no use in mirroring it on an IPv6 capable host.
So we're out of luck, until Ubuntu fixes their network.

IPv6 has now been added to other official Canonical resources including and, amongst other repositories, since the last time this bug was updated.

It appears that these are hosted on or very close to the same network as launchpad -- can this be raised for some discussion? Ubuntu/Canonical made great progress on v6 in the last 18 months, it would be great to carry some momentum from it.

Any News like adding an IPV6 address to hosts?
