Untracked dependencies

libxcb

Napari depends on Qt5 which in turn depends on libxcb on Linux. libxcb and its related libraries should be installed through your distribution's package manager (e.g. apt) and not through Conda.

To see Qt's dependencies on libxcb and what might be missing, run the following command:

ldd <PATH_TO_CONDA>/envs/napari/lib/python3.9/site-packages/PyQt5/Qt5/plugins/platforms/libqxcb.so

Alternatively, you can try launching Napari with Qt in debug mode to see the missing libraries.
