Public bug reported: On my local network I find that with 18.04 network name lookups using .local domains no not work unless stimulated by a non-18.04 machine first. This is observed for ssh, http, https and ping, but probably not limited to those.
To demonstrate this here is a ping example. ~ $ ping pi.local ping: pi.local: Name or service not known ~ $ ping pi.local ping: pi.local: Name or service not known # At this point head to another machine running 16.04.6 and execute ping pi.local. # This is immediately successful. Then head back to the 18.04 machine. ~ $ ping pi.local PING pi.local (192.168.108.28) 56(84) bytes of data. 64 bytes from pi.this.domain (192.168.108.28): icmp_seq=1 ttl=64 time=4.43 ms 64 bytes from pi.this.domain (192.168.108.28): icmp_seq=2 ttl=64 time=5.64 ms 64 bytes from pi.this.domain (192.168.108.28): icmp_seq=3 ttl=64 time=5.98 ms 64 bytes from pi.this.domain (192.168.108.28): icmp_seq=4 ttl=64 time=5.84 ms ^C --- pi.local ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 7018ms rtt min/avg/max/mdev = 4.435/5.476/5.986/0.613 ms After a couple of minutes, the name resolution fails again, but can be brought back again by following the procedure above.
