Hi all,
i run the script and it works for my main instance...but i have a second one and the server is down...i reverted...
Any solution for the second instance to work please?
Thanks
What we have to do for who have two instance on Octoprint, for two printers. I did install on the first one and on second instance the system ask me me to do the same upgrade ? did i have to do for all instance ?
Besides Octoprint, I do run Klipper on my Octopi and don't want to revert to Marlin. The main branch of Klipper is not yet ready for Python 3, so I guess I can't upgrade. Or am I missing something?
Hey, a script that works the first time and didn't require me to Google something to get it to work, nice!
Ran on my custom setup of OctoPrint on Raspberry Pi OS, and everything worked as it should.
One point of feedback: It doesn't say what the default config directory is, like it does for the OctoPrint env and service commands, but it wasn't too difficult to figure out.

So, decided to give it a try on my one box. I now continue to get "Not an OctoPrint backup, lacks metadata.json" when I go to restore the setup even though the ZIP file clearly contains that file. Fails whether I upload directly through an SFTP connection or through the OctoPrint interface. Create a backup of the raw system and that restores fine as long as I don't download it first and then try and restore it. Not sure what is failing but now I get to rebuild that Pi with my configuration. So to others, be careful if you chase this also.
Hi @Oli_vier
Could you open a new 'Get Help' topic with the information requested (logs etc.). Thanks!
Hi @FullReg
You would have to do it for each instance you run.
If you are on OctoPi, use the -c flag, so that you can enter the details of where your 2nd install is located.

Hey @Detlev_Rackow!
Your Klipper install will not be affected unless it is in the same virtual environment (Which it shouldn't....) . However, if you are using the Klipper Plugin, someone mentioned it was not Py3 compatible.
Hey guys can you help me with this error that I'm getting:

Seems like something has gone wrong with the backup of that install.
Could you try running ~/oprint/bin/octoprint plugins backup:backup --exclude timelapses --exclude uploads, and see if an error is generated there.
To reply to myself. I have Windows running in Parallels and decided to use MS Edge to pull a copy of a similar backup from another OctoPi instance, .... restored that to the refreshed box and it works..... Something in Safari and FireFox on a Mac I suppose. That will be a good enough workaround for me, but weird in general. I can start another thread to have that looked at.

Hey folks, just mentioning this in case it helps other newbies. I didn't realize that the instance of Python that's used by OctoPrint is separate from the one that's used by Raspberry Pi OS.
You can see the OctoPrint Python version number by scrolling to the bottom of the OctoPrint web page.
Kudos to @Charlie_Powell for setting me straight on this.

worked flawless besides the known bed leveler plugin, which also compiled single core for over 15min to tell me, it is not working properly afterwards. ;D

Worked perfectly for me as well (after the long process of upgrading OctoPi and other things I had to reinstall.)

There is a python 3 compatible fork and that person is taking over as maintainer to the official repo.

You probably just need to run the command shown on the known issues page...
