The log did not provide any clues...pihole -up isn't something we usually check for when debugging. Will you send the output of this command to tricorder (assuming it's the pihole -up command you are having issues with)?
[xbian@kitchen ~ $ systemctl status dnsmasq
Failed to get D-Bus connection: Unknown error -1
xbian@kitchen ~ $ service dnsmasq status
-bash: service: command not found
Sorry but how do you do code tags for posting on here?
So it looks like something is wrong with systemd...do you have trouble with anything else on your system? It seems like Pi-hole is working, but probably not reloading dnsmasq since those commands are failing.
Well, that was a pleasant read from a jolly fellow. If upstart is the init system instead of systemd then the issues you are seeing are stemming from that. The errors you are seeing though would not prevent the Pi-hole from functioning, but Xbian is not one of our supported platforms. If a Pull Request is submitted to include Xbian support, we'd appreciate it.
TBH he is a very patient and helpful person, I think that maybe it was bad timing or just a bad day for him. Anyway I will relay your request for a pull and see what happens.
I doesn't seem to affect the operation, but error messages are always worth looking into.
