Problema realmente estranho com python

0
Em primeiro lugar eu tenho problema com cafeína: A cafeína não funciona no Ubuntu 17.10

Eu não liguei com python. BTW, rodar o Ubuntu no Xorg não ajudou.

Em segundo lugar, recebi um erro estranho ao tentar testar o programa python. Eu corri

 python3 programname.py test

e receba

File "sampletest.py", line 1, in <module>
    import unittest
  File "/usr/lib/python3.6/unittest/__init__.py", line 59, in <module>

Em seguida, recebi um erro após executar o alacarte: Como posso ordenar a lista de menu de whiskers do Xfce em ordem alfabética?

BTW, eu recebo o erro semelhante quando executar menulibre:

/usr/lib/python3/dist-packages/menulibre/MenuEditor.py:28: PyGIWarning: GMenu was imported without specifying a version first. Use gi.require_version('GMenu', '3.0') before import to ensure that the right version gets loaded.

    if not self.tree.load_sync():

Tenho certeza de que há problemas no meu interpretador python, mas não sei o que pode ser. Por favor, ajude

P.S. Eu sou novo no linux. Então, por favor, explique o mais simples possível

P.P.S. Eu tenho o Ubuntu 17.10

Para menulibre parte, você deve reinstalá-lo com suas dependências:

sudo apt-get update
sudo apt-get install --reinstall gir1.2-gmenu-3.0 gnome-menus libgnome-menu-3-0 menulibre

Em seguida, inicie-o com o comando menulibre ou no menu.
