mirrors.ubuntu.com inaccessible via current Internet Protocol a.k.a. IPv6

[Anderson Silva]

I set-up my APT repositories to use mirrors://mirrors.ubuntu.com and, while trying to update my system packages in an IPv6-only connection, it fails because the server becomes unreachable:

Is this still an issue?
There has been no response to comment #2 for over a month now.

The Ubuntu project is for bug reports relating to installations on user's computers.

Is https://github.com/canonical a better location to report this issue?

[Anderson Silva (undereu)]

Yes, the issue is still going.
