netinstall on wine

Trying to update a hAP lite from 6.43.4 to 6.44.6.

I don’t run Windows so I’m running Netinstall 6.44.6 (and I've also tried 6.46.2) with Wine 4.0 on Ubuntu 19.04

Wireshark shows packets coming in to the Ubuntu platform.

and Netinstall command line shows -

But the Mikrotik device never registers on the Netinstall window.

udp 0 0 0.0.0.0:67 0.0.0.0:* 5157/netinstall6446
udp 0 0 0.0.0.0:69 0.0.0.0:* 5157/netinstall6446

Netstat shows that netinstall has UDP ports 67 and 69 open. There is no firewall up. The Ubuntu platform is directly connected to Ether1 of the Mikrotik.

Any ideas?
