Thanks for all that information, but first of all using just import
adafruit blinka did not work as it returned bas: import: command not found.
Were you in the Python3 interpreter? That error (I presume it was
"bash:...") means you typed the line at the console shell, not into a
from: can't read /var/mail/Python3from shell console
Python interpreter.
pi@raspberrypi:~$ #from shell console

I should say that this is on a raspberry pi zero w, if it makes any
difference.
It doesn't... All R-Pi system use a default OS of Raspbian (a Debian
modified for R-Pi specific booting and support) {caveat: if using a NOOBS
installer with active WiFi one does have the option of installing any one
of half a dozen OSes, though some are quite specific in usage: Windows IoT,
media player...}
It doesn't even matter if one is using a BeagleBone Black, since that
also runs Debian (though R-Pi has updated to "Buster" while the BBB is
still on "Stretch" [ver 10 vs ver 9]).

It does matter if you try from a system that doesn't support embedded
programming -- Debian 10 running in a VirtualBox instance on a Window10
computer...
Actually -- it did do something
wulfraed@debian:~$ import adafruit_blinka

It created a large file that, on examination, is an EPS image file of my
Debian desktop! "import" appears to be a command supplied as part of
"ImageMagick" conversion utility.
After removing the file, the Python3 interpreter reports
wulfraed@debian:~$ python3

import adafruit_blinka
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'adafruit_blinka'
exit()
wulfraed@debian:~$
as expected, since the AdaFruit libraries are not installed on a desktop
machine.
No I wasn't in the Python3 interpreter, and typing
Python3 gets me into, I assume.
Then typing:
import adafruit_blinka seemed to work as there were no errors.
Thanks
