I've made important progress. I figured out how to use Conda, and I also found my Python interpreter path in a new environment I created.

Did I install all of those Python packages (sudo apt-get install) for nothing? If I set Sigil's "Path to Interpreter Executable" to the Conda interpreter, it seems to me that all the packages listed under the "Getting Python 3.9+" section in the "Building Sigil on Linux with Qt6" guide won't be used. Am I right about this? My hunch says yes. Among the errors I see in the plugin with the Conda venv are these:

Python Package: cssselect Missing
Python Package: css-parser Missing
Python Package: html5lib Missing
Python Package: lxml Missing
Python Package: regex Missing
Python Package: chardet Missing

Some of these packages have identical names to the packages the guide said to install with apt-get. They weren't previously missing when my Sigil interpreter was set to /usr/bin/python3.

If I'm right, then I can take this a step further. Would I be exclusively running "pip install" inside the venv? I'm not sure the venv understands distro specific commands such as apt-get and pacman.
