Octoprint won't start - No module named 'zipstream.ng'

[wagz]

What is the problem?

I leave my Raspberry Pi running all the time. A print completed normally in my absence. I found that the octoprint web interface was unavailable. I don't believe that the pi was ungracefully restarted.

Output of the 'octoprint' command ALWAYS returns:

Traceback (most recent call last):
  File "/usr/local/bin/octoprint", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.9/dist-packages/octoprint/__init__.py", line 1006, in main
    from octoprint.cli import octo
  File "/usr/local/lib/python3.9/dist-packages/octoprint/cli/__init__.py", line 347, in <module>
    from .systeminfo import cli as systeminfo_commands  # noqa: E402
  File "/usr/local/lib/python3.9/dist-packages/octoprint/cli/systeminfo.py", line 10, in <module>
    from zipstream.ng import ZIP_DEFLATED, ZipStream
ModuleNotFoundError: No module named 'zipstream.ng'

This message occurs with any ivocation of 'octoprint' including 'systeminfo' and 'safemode'

What did you already try to solve it?

Restarting the service. no different. I followed some other forum advice to reinstall octoprint.

source ~/oprint/bin/activate
pip install --force-reinstall OctoPrint

Have you tried running in safe mode?

yes. any invocation of octoprint returns this:

pi@ender3:~/.octoprint/logs $ octoprint safemode
Traceback (most recent call last):
  File "/usr/local/bin/octoprint", line 8, in <module>
    sys.exit(main())
  File "/usr/local/lib/python3.9/dist-packages/octoprint/__init__.py", line 1006, in main
    from octoprint.cli import octo
  File "/usr/local/lib/python3.9/dist-packages/octoprint/cli/__init__.py", line 347, in <module>
    from .systeminfo import cli as systeminfo_commands  # noqa: E402
  File "/usr/local/lib/python3.9/dist-packages/octoprint/cli/systeminfo.py", line 10, in <module>
    from zipstream.ng import ZIP_DEFLATED, ZipStream
ModuleNotFoundError: No module named 'zipstream.ng'

Did running in safe mode solve the problem?

No change

Systeminfo Bundle

I can't pull a systeminfo bundle because the octoprint command always throws the zipstream error.

Additional information about your setup

I think this is v1.9.2

'octoprint version' throws the same error.

Have you checked the SD card? How full is it?

Tried installing zipstream-ng to no avail. I'm unsure about the invalid distribution issue. I haven't done anything but install this from the rpi imager and use it for several months. I haven't been mucking around with python packages.

More digging - I'll eventually mess this up enough to have to reimage it from scratch.
