最近我从 20.10 更新到了 Ubuntu 21.04。更新完成后几天内一切都正常了。我收到了系统更新通知和安全更新等。但几天前，我正考虑更新我的系统并尝试打开“软件和更新”（我知道这不会更新系统，请继续阅读）但我的错，我错误地点击了它，所以再次从应用程序列表中我点击了“软件更新程序”，但没有更新，我以为可能出了问题，我点击了设置按钮，然后出现一个提示说要报告，我很困惑，然后我意识到是什么software-properties-gtk导致了这个问题，并没有给我系统更新通知等等。然后在终端中我输入了以下内容sudo software-properties-gtk，这是我得到的输出：
lmao@lol:~$ sudo software-properties-gtk

请不要将此问题标记为重复这个问题。 因为这个问题有File "/usr/lib/python3/dist-packages/UbuntuDrivers/detect.py"问题，但我的就是File "/usr/lib/python3/dist-packages/dbus/bus.py"。请帮我解决这个问题，从终端编辑存储库对我来说有点困难，所以我用它作为存储库编辑器度过了愉快的时光。（不是完全的，我总是使用终端来添加它们，只是用来software-properties-gtk禁用它。）
