I recently followed this guide to get wireless working on a fresh install of Ubuntu 19.10: https://www.linuxbabe.com/ubuntu/connect-to-wi-fi-from-terminal-on-ubuntu-18-04-19-04-with-wpa-supplicant#comment-46373
On boot the DHCP service runs and I get this error:
ieee80211 phy0: brcmf_inetaddr_changed: fail to get arp ip table err:-52
So I Alt-F4, login and run it manually using sudo dhclient. I get this error:
ieee80211 phy0: brcmf_inetaddr_changed: fail to get arp ip table err:-52
cmp: E0F on /tmp/tmp.Itr1VGx0mk which is empty
But then I get an IP and everything seems to work. Here's the output of the log file:

How can I have DHCP run successfully on boot?
For reference, my hardware is a MacBook Pro, late-2015.
