全新 sys76 Thelio 桌面，搭载 ubuntu 20.04
在安装过程中，在链接在线帐户（谷歌）时，安装挂起，我不得不硬重启。安装似乎在重启后重新开始，这次跳过了链接在线帐户。安装完成，一切似乎都很好。然而，当我尝试启动软件更新时，它崩溃了。我重新启动并再次尝试启动软件更新，结果还是一样。
看来，除非我修复了这个问题，否则我将无法安装或升级软件。如能提供任何有关如何修复这个问题的帮助，我将不胜感激。谢谢。

答案1
长话短说，经过一番研究和检查日志后，我决定尝试重新安装一些东西。为此，我尝试了以下操作：
sudo apt-get install --reinstall dbus python-dbus python3-dbus
幸运的是，这似乎解决了这个问题。
