[1] specifically mentions the desired partition layout.
Force the installer to do this:
#1 primary 314.6 MB B K ESP
#2 primary 1.0 GB f swap swap
#3 primary 14.7 GB f ext4 /

ESP is /boot/efi. /boot is a part of / that's yet to be created.
On a side note, I took a spare RPi3 and followed [1] myself.
First, I'd like to express huge thanks to all DDs and DMs that made
possible to boot and run a proper OS on RPi3. I can provide an
installation-report in case someone's interested.
Second, some wishlist bugreports are in order. It's not an installation
that took the most of the effort, it's the camera that's attached to the
said RPi3.
