cp2004/Octoprint-Upgrade-To-Py3

Command line option --allow-releaseinfo-change is not understood in combination with the other options

Hardware: raspberry pi 3B
OS: Raspbian GNU/Linux 9 (stretch)
Environment:

  • OctoPrint: 1.7.2
  • Python: 2.7.13 (you have 2.7.13)
  • pip: 19.0.1 (you have 18.0)
  • setuptools: 40.7.1 (you have: 40.2.0)

I have already installed Python3.7.4 manually und updated OctoPrint to 1.7.2. The screenshot below shows what I've done to for upgrade.py. And I got this:

E: Command line option --allow-releaseinfo-change is not understood in combination with the other options.

I think the reason for this error is due to the fact that my system is the stretch version. How do I fix this problem without reinstalling my system?

Probably easiest to edit the script to remove the extra argument - maybe older versions of apt & co don't have that option. I didn't design the script to work on Debian OSes where Python 3.6+ was not available in the repositories.

You can find it on line 193 to remove it.

@cp2004 Thanks for your help. Finally I successfully updated OctoPrint's environment to Python 3.7.4. So you can close this issue now. I will document my procedure below in case someone else has encountered similar problems.

Error: E: Command line option --allow-releaseinfo-change is not understood in combination with the other options
Operation: removed the argument --allow-releaseinfo-change and reran the script 'upgrade.py'

Error: Failed to create Python 3 venv because of ModuleNotFoundError: no module named apt_pkg

Operations:

  • cd /usr/lib/python3/dist-packages/
  • sudo ln -s apt_pkg.cpython-37m-x86_64-linux-gnu.so apt_pkg.so
  • sudo apt-get upgrade
  • sudo apt-get --fix-broken install
  • sudo apt-get remove python3.5*
  • sudo apt-get autoremove

Thanks for getting back with the full steps that worked for you to get it running. I'll keep it in mind if I see other issues. Although now it makes it easier to see why I didn't recommend the manual Python installation approach, especially to people who didn't know what they were doing as they wouldn't have been able to figure that out. 👍
