the wifi setup should be done by the first boot configuration tool, if
you connect a serial tty or display on first boot you should see a
"please press enter" message after the boot messages, if you press
enter there you get walked though the initial system configuration
which also sets up the necessary wifi bits ... note that finishing this
wizard is essential since it also sets up the ssh keys for logging in.

if you have wifi problems after using this tool (which uses netplan in
the backend, as jian said), please file bugs against [1]. the
/etc/network/interfaces file is deprecated and netplan config should
not be done manually either.
