Erro ao iniciar o system-config-printer

Question

Instalei drivers de impressora EPSON usando a linha de comando e agora não consigo iniciar a configuração da impressora. Segue o traceback:

Traceback (most recent call last):
  File "/usr/share/system-config-printer/system-config-printer.py", line 29, in <module>

Original exception was:
Traceback (most recent call last):
  File "/usr/share/system-config-printer/system-config-printer.py", line 29, in <module>
    import dbus
  File "/usr/lib/python3/dist-packages/dbus/__init__.py", line 77, in <module>

  File "/usr/lib/python3/dist-packages/dbus/types.py", line 6, in <module>
    from _dbus_bindings import (
ModuleNotFoundError: No module named '_dbus_bindings'

eu usei

sudo apt-get install --reinstall software-center python-dbus
sudo apt-get install python3-dbus python3-dbus.mainloop.qt

mas ainda estou recebendo o erro.

    

Answer 1

Eu encontrei o problema. Eu tinha instalado o python 3.6 e configurei o / usr / bin / python3 para ele. Mudar / usr / bin / python3 de volta para o python 3.5 resolveu o problema.

sudo rm /usr/bin/python3

sudo ln -s python3.5 /usr/bin/python3
