Ubuntu 22.04: pipx install buku[server] failing.

[DiagonalArg]

Ubuntu 22.04. It's nearly a year ago I posted on this, but it's still failing. If it's actually been fixed, it needs to be uploaded to PyPI.

$ pipx install buku[server]
Fatal error from pip prevented installation. Full pip output in file:
    /home/user/.local/pipx/logs/cmd_2023-06-22_16.34.58_pip_errors.log

pip seemed to fail to build package:
    buku[server]

Some possibly relevant errors from pip install:
    ERROR: Packages installed from PyPI cannot depend on packages which are not also hosted on PyPI.

Error installing buku from spec 'buku[server]'.

$ cat /home/user/.local/pipx/logs/cmd_2023-06-22_16.34.58_pip_errors.log
PIP STDOUT
