I ran into the same problem with 17.10 and I solved it without any fixed or workarounds. But this is not an ubuntu bug! It's a false configuration. There are 2 Options for automatic IPv6 configuration in network manager. "Automatic" and "Automatic (DHCP only)". IPv6 router advertisment is not part of dhcpv6 by spec! So I switch my config to "Automatic" which uses dhcpv6 and router advertisment. The kernel option /proc/sys/net/ipv6/conf/ethX/accept_ra is set to 1 (active) then! Problem solved!
