2017-07-10 Raspbian mirrors sometimes fail when IPv6-only 3 years ago
Just happening:Err http://mirrordirector.raspbian.org/raspbian/ jessie/main libgcrypt20 armhf 1.6.3-2+deb8u4 Cannot initiate the connection to raspbian.42.fr:80 (18.104.22.168). - connect (101: Network is unreachable) [IP: 22.214.171.124 80]It seems mirrordirector.raspbian.org redirects to IPv4-only sites even when the client connects via IPv6. My Raspberry Pi systems have IPv4 disabled. It's a known problem in Bug #1595563 “Native IPv6 client redirected to IPv4-only mirror” : Bugs : Raspbian where people seem to rather ignore the problem. I could reverse the statement there to "a service that can only be accessed by v4 nodes cannot be reasonablly considered to be available on the internet." but I guess that's "different". Oh and the fix is to change http://mirrordirector.raspbian.org/raspbian/ to http://mirror.mythic-beasts.com/raspbian/raspbian/. I trust Mythic Beasts to keep their systems reachable via IPv6.
