Comment # 12 on bug 1097370 from Bernhard Wiedemann

Something went wrong with the apparmor update:
wget
http://download.opensuse.org/update/leap/15.0/oss/noarch/apparmor-abstractions-2.12-lp150.6.6.1.noarch.rpm
unrpm apparmor-abstractions-2.12-lp150.6.6.1.noarch.rpm
grep resolv.conf etc/apparmor.d/abstractions/nameservice 
  /{,var/}run/{resolvconf,NetworkManager,systemd/resolve,connman}/resolv.conf
r,

and that is why my dnsmasq could not resolve anything
> Feb 25 09:28:43 bernhard dnsmasq[3510]: failed to read /etc/resolv.conf: Permission denied
> Feb 25 09:28:43 bernhard dnsmasq[3510]: no servers found in /etc/resolv.conf, will retry


should be
 
/{,var/}run/{resolvconf,NetworkManager,systemd/resolve,connman,netconfig}/resolv.conf
r,

as added by applied patch9: apparmor-nameservice-resolv-conf-link.patch
