Linux Mint 21.1 issue installing DisplayCal with py3

[mateimm]

Hello, I am following the installation steps and when I run the command pip install -r requirements.txt I get the below error message:

Program python found: YES (/home/matei/displaycal_venv/bin/python)
      Dependency dbus-1 found: YES 1.12.20 (cached)
      Run-time dependency python found: YES 3.10

      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I'd like to mention that the full log is not generated. There is nothing in the /tmp/ folder related to pip-install... as mentioned in the error message.

Thanks for your help.

I, shortly after posting the above message, found DisplayCal as a flatpak. I will install it from there.
