I get an error during the update.

I'm start the update TinyPilot with:

/opt/tinypilot/scripts/upgrade && sudo reboot

And get error:

ERROR: Could not find a version that satisfies the requirement pkg-resources==0.0.0 (from versions: none)
ERROR: No matching distribution found for pkg-resources==0.0.0

I tried install fresh copy with:

curl \
  --silent \
  --show-error \
  https://raw.githubusercontent.com/tiny-pilot/tinypilot/master/quick-install | \
    bash - && \
  sudo reboot

And get same error.

Can you help me fix this?
