For this exercise during installation at very beginning select:
“Manual Network”
I set a static ip, and provided credentials.
This will write your wifi config as the default in /etc/network/interfaces
Further into installation when it progresses to asking if you want to create a new UCS Domain, or Join a domain, etc…
⬦ Press Ctrl + Alt + F5 or whatever your key bindings are for dropping to tty.
⬦ Login as root using the password you supplied for your user earlier.
**Type this at # prompt **
wpa_passphrase ssid password > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf (substitute wlan0 for whatever your wifi interface name is )
Then type this: systemctl enable --now wpa_supplicant@wlan0
Test with a ping to something like 1.1.1.1
Type"exit" to leave tty and setup should resume. If it does not then restart the computer and it should continue setup.
