Unbound stopped working properly after a power break

just noticed this in your unbound config. Did you read this? This basically creates a DNS loop, which makes the system behave unpredictable.

basically, it comes down to:

  1. edit /etc/resolvconf.conf, make it look like this:
#dnsmasq_resolv=/var/run/dnsmasq/resolv.conf
pdnsd_conf=/etc/pdnsd.conf
#unbound_conf=/etc/unbound/unbound.conf.d/resolvconf_resolvers.conf

comment out the unbound line (#).

  1. delete the file /etc/unbound/unbound.conf.d/resolvconf_resolvers.conf

  2. restart unbound
