On fedora 29, unbound-1.8.3-2.fc29.x86_64
unbound-checkconf
[1550270441] unbound-checkconf[1581:0] fatal error: interface: ::1 present twice, cannot bind same ports twice.
I'm not ipv6 enabled, so no ipv6 in unbound.conf :
grep interface /etc/unbound/unbound.conf | grep -v \#
interface: 127.0.0.1
interface: 10.10.11.251
interface-automatic: no
Any help appreciated.
