Não consigo abrir a ferramenta de ajuste do Unity [closed]

Question

Não consigo abrir a ferramenta de ajuste [Unity] [1], nem do lançador nem do painel nem do terminal. No terminal, recebi esses erros:     t *** @ t *** - área de trabalho: ~ $ unity-tweak-tool

Traceback (última chamada mais recente):

 File "/usr/bin/unity-tweak-tool", line 72, in <module>

 UnityTweakTool.Application()
File "/usr/lib/python3/dist-packages/UnityTweakTool/__init__.py", line 79, in __init__
 executable_name=cmd_old.split('\x00')[1]

IndexError: índice de lista fora do intervalo

Como posso resolver este problema?

Atualizar Recebi outro erro do lançamento do terminal:

WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Execute o bleachbit do terminal como SUDO e limpe o cache do sistema. Eu tive o mesmo problema e resolvi isso.
