Eu comecei a receber esse erro no Arch Linux. O hp-setup tem funcionado bem até agora. Eu não entendo a mensagem de erro.

Depois de ver este erro, eu reinstalei o hplip (que é o pacote que possui o arquivo hp-setup).
pacman -Qo /usr/share/hplip/setup.py
/usr/share/hplip/setup.py is owned by hplip 3.17.11-1
Isso não resolveu o problema.
O erro ocorre sem nenhuma opção de linha de comando (cujo padrão é o modo GUI) ou com a opção --gui . No entanto, com a opção --interactive (que é um modo somente texto), não obtenho o erro.
Outro computador Arch com uma configuração idêntica (no que diz respeito a pacotes instalados e configurações) não possui o erro (mesmo com o modo GUI).

A solução foi simples:
pacman -S --needed python-gobject
e, de fato, precisava ser instalado.
O relatório de pacman -Qi hplip que indicou:
python-gobject: for running hp-toolbox [installed]
foi enganador. Quando eu corri o pacman -Qi python-gobject , descobri que ele não estava realmente instalado. Instalá-lo resolveu o problema.
