http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=6a79acb0 This bug makes most IPv6 connections unusable without manual intervention (either setting the hop limit on each router that does not set that in RAs - most!) or manually changing the limit after every connection. I wouldn't say it's critical (most of us still have IPv4 access too :), but it's definitely a High importance bug. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1450066 Title: IPv6 hop limit set to 0 Status in network-manager package in Ubuntu: Confirmed Bug description: On upgrading from Ubuntu 14.10 to 15.04 I found that my IPv6 networking no longer worked. It turned out that this was because my hop limit was set to zero: # sysctl -a | fgrep eth0.hop_limit net.ipv6.conf.eth0.hop_limit = 0 which in turn seems to have been cause by a known problem in the network manager: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756534 https://bugzilla.gnome.org/show_bug.cgi?id=737252 Since this has already been fixed in the GNOME project, can Ubuntu 15.04 please take the upstream fix?
