He instalado QGIS3 desde el paquete AUR, así como todas las dependencias opcionales: https://aur.archlinux.org/packages/qgis/
Sin embargo, al iniciar, recibo el siguiente error:
Couldn't load plugin 'processing'
ModuleNotFoundError: No module named 'osgeo'
Traceback (most recent call last):

Parece ser un problema de ruta, pero no estoy seguro de cómo resolverlo. Pacman muestra gdal y python-gdal como instalados.
python-gdal
resolvió este problema para mí. Parece que han olvidado una dependencia.
