I think the problem is not related to NetworkManager but dhclient itself. Trying to use DHCPv6 in a Debian 8 machine (no GUI/NM) (using "iface eth0 inet6 dhcp" in /etc/network/interfaces) the "dhclient -6" instance is not started either). Only after I run dhclient manually once (as observed by the OP) it starts working. I use:
# dhclient -6 -d eth0 Doing this the DUID (type 1) is generated and the configuration manager works as expected (networkmanager in Ubuntu or ifup/ifdown in Debian). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1484932 Title: ipv6 dhcp client never started.
