  ERROR: Failed building wheel for tpm2-pytss
Failed to build tpm2-pytss

[notice] A new release of pip is available: 25.1.1 -> 25.3
[notice] To update, run: pip install --upgrade pip
ERROR: Failed to build installable wheels for some pyproject.toml based projects (tpm2-pytss)

[whooo]

Please install directly from the git repo, so python3 -m pip install git+https://github.com/tpm2-software/tpm2-pytss.git
The bug has been fixed, but is not part of any release on pypy yet.

understood, thanks!
