I wanted to use Unbound on my Pi-Hole installation, but as soon as I adjust the upstream server, Pi-Hole stopped resolving.
Yesterday I finally found the solution (source):
All your unbound DNS queries are being forwarded to your router.
- Edit file
/etc/resolvconf.confand comment out the last line which should read:
- Delete the unwanted unbound configuration file:
sudo rm /etc/unbound/unbound.conf.d/resolvconf_resolvers.conf
- Restart unbound:
sudo service unbound restart
This solved the issue on my installation. With Unbound, everyday browsing seems a little bit faster. I can highly recommend it if you are using Pi-Hole.
