It works totally fine for millions of users. I have never seen a single network where it does not work. I've heard about it in a few bug reports, like this one. AFAIUI that involves a globally routable IPv6 address, but no actual IPv6 connectivity to the hosts. Which is not normal. Hence the suggestion to fix that.
As mentioned before, we're actively working on adding "happy eyeball's" - fast fallback from IPv6 to IPv4 - but this takes time, and more bug reports about it do not help. It's just distracting. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1740114 Title: apt's IPv4 fallback in case of a malfunctioning IPv6 connection works horribly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1740114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
