What is the problem?
I turned on my printer for the first time in 3.5 years and my OctoPrint 1.4.0 using an RPi 3 booted just fine. It's (obviously) just incredibly out of date. I tried updating through the update function in OctoPrint, and it was failing. I decided to make a backup, replace the board with a RPi 4 and started with a fresh image from the Raspberry Pi Imager (as suggested) and then tried to restore the 250MB backup I made and it keeps failing with the below errors:
Error while running restore
Traceback (most recent call last):

Restore failed! Check the above output and octoprint.log for reasons as to why.
What did you already try to solve it?
I have researched and it looks like someone in another thread suggested upgrading to 1.7 and creating a new backup and starting from there. I found instructions and used the following command:
~/oprint/bin/pip install --force-reinstall OctoPrint==1.7.0 --no-cache-dir
but after a little bit, I get the following error:
