Hello Michael, One thing I have noticed about this:
(c)inaddy@temp:~$ systemctl status radvd ● radvd.service - Router advertisement daemon for IPv6 Loaded: loaded (/lib/systemd/system/radvd.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:radvd(8) Jul 08 15:49:06 temp systemd[1]: Starting Router advertisement daemon for IPv6...

Jul 08 15:49:09 temp systemd[1]: Stopping Router advertisement daemon for IPv6... Jul 08 15:49:09 temp systemd[1]: radvd.service: Succeeded. Jul 08 15:49:09 temp systemd[1]: Stopped Router advertisement daemon for IPv6. Jul 08 15:49:20 temp systemd[1]: /lib/systemd/system/radvd.service:11: PIDFile= references path below legacy directory /var/run/, upd After the reboot, the service is NOT enabled by default, likely because of missing radvd.conf file in /etc. What you are seeing is just a deprecated warning message (15:49:20) after reboot, but I was able to manually start my service after reboot. The real issue here could be not having radvd.conf file created by default, at least a simple one like this: interface eth0 { AdvSendAdvert on; prefix 2001:db8::/64 { }; }; And, possibly, the installation would enable radvd.service by default. In the second boot I have enabled radvd and after a new reboot it goot started automatically: ● radvd.service - Router advertisement daemon for IPv6 Loaded: loaded (/lib/systemd/system/radvd.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2019-07-08 15:53:05 UTC; 35s ago Docs: man:radvd(8) Process: 244 ExecStartPre=/usr/sbin/radvd --logmethod stderr_clean --configtest (code=exited, status=0/SUCCESS) Process: 350 ExecStart=/usr/sbin/radvd --logmethod stderr_clean (code=exited, status=0/SUCCESS) Main PID: 354 (radvd) Tasks: 2 (limit: 4915) Memory: 1.3M CGroup: /system.slice/radvd.service ├─354 /usr/sbin/radvd --logmethod stderr_clean └─355 /usr/sbin/radvd --logmethod stderr_clean Jul 08 15:53:05 temp systemd[1]: Starting Router advertisement daemon for IPv6...
