What is the problem?

I thought that the Octopi 0.18.0 image came with Python 3.6. When I check the version it is 2.7.16.
How can I upgrade to 3.6?

What did you already try to solve it?

I downloaded the "Latest Stable Build" today from Octoprint.org.
I used BalenaEtcher to extract the image to my uSD card that used to have a working 0.17.0 image on it.
I configures the octopi-wpa-supplicant.txt file for my network.
I booted the Raspberry Pi 4 then SSH'd to it to configure some of the settings with sudo raspi-config
When I logged into the the new image and queried the Python version, I see:

------------------------------------------------------------------------------
Access OctoPrint from a web browser on your network by navigating to any of:

    http://octo2pi.local
    http://172.16.0.35

https is also available, with a self-signed certificate.

This image comes without a desktop environment installed because it's not 
required for running OctoPrint. If you want a desktop environment you can 
install it via

    sudo /home/pi/scripts/install-desktop
------------------------------------------------------------------------------
OctoPrint version : 1.5.2
OctoPi version    : 0.18.0
------------------------------------------------------------------------------

pi@octo2pi:~ $ python -V
Python 2.7.16
pi@octo2pi:~ $

I searched on the web and tried to upgrade, but I see a message that Python 3 is already installed.

Have you tried running in safe mode?

No.

Did running in safe mode solve the problem?

You're looking at the default system python version. You need to look inside the virtual env (~/oprint/bin/python -V), and also listed on the OctoPrint home page in the bottom left hand corner of the footer.

Thanks Jnei,
I am not an expert. I ran into this problem when I tried to install the Google Drive Backup Plugin. Do you have any suggestions?

4

Use ~/oprint/bin/python for anything OctoPrint related.

Or just source ~/oprint/bin/activate

5

I tried your suggestion and:

pi@octo2pi:~ $ source ~/oprint/bin/active
-bash: /home/pi/oprint/bin/active: No such file or directory

How would I edit the plugin installation?

Thanks.

Spot the difference :wink:

How can I add that command so that it takes effect on boot up?
