root@dimension:/home/bp1# lsb_release -a

3) DNS resolution
4) No DNS resolution from my configured DNS (in my case 192.168.1.1)
Workarounds:
Enable FallbackDNS=8.8.8.8 8.8.4.4 in resolved.conf
Or running dhclient
Fresh boot of Artful (static IP via network manager and DNS should be at
192.168.1.1):
