This bug is due to a failure in handling router advertisments. According to RFC 4861 (page 20) a _Cur Hop Limit_ set to 0 means, that the Hop Limit is unspecified. Ubuntu 15.04 takes this literally and sets HL to 0.
Fortunately my router provided the option to set this field to a manual value, altough i suppose this is not the case for most routers. -- 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: Triaged Status in network-manager source package in Vivid: Triaged 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?
