Can't update Octoprint from 1.6.1 to 1.7.3

[ampedpfv]

I'm trying to update from 1.6.1 to 1.7.3, but I receive the attached error and the update is aborted.
Can someone help me understand what this error means? And/or provide a possible solution (ie. do I need to backup and reinstall Octoprint or is there some other method via CLI?).

I did a sudo apt update and sudo apt upgrade also.
I'm running on a Raspberry Pi 4

Hello @ampedpfv !

You are running on Python 2.7. OctoPrint 1.7.0 and higher requires Python 3.

I recommend to make a backup and start all over with a recent OctoPi installation.

[ampedpfv]

Thank you!
I'll try that and report back.
I just tried updating the pi to the latest Python version 3.12 and setting it as the default, but it didn't work, so I think it's better to start over as you suggested.

So for anyone else reading this, I solved this with two steps:

1. Install the latest version of Python 3 on the PI.

2. Update Octoprint to use Python 3 using the instructions at the below link:

@Ewald_Ikemann thanks for pointing me in the right direction!
