"Installation of a custom driver is required only for kernels older
than 4.8."

You try to run DKMS to build the "driver". Not installing the driver
fails, already building the driver fails.

DKMS tried to build the module for a kernel 4.8, not for a kernel < 4.8.

Seemingly it should work by using a kernel >= 4.8 without building a
kernel module ("driver").

Also from the above link:

"echo "options rtl8723be ant_sel=2"  | sudo tee /etc/modprobe.d/rtl8723be.conf
[snip]
But still if your laptop has only one antenna and it is attached to a
"wrong" connector, setting ant_sel=2, or and_sel=1 may be required."

Did you try it?
