我无法更新我的系统 Ubuntu 14.04，因为软件更新程序没有运行。此外，我无法运行 Ubuntu 软件中心。所有这些问题都是在我尝试对系统进行部分升级后出现的。我就这样更新了我的系统，但它显示某些应用程序只有在我进行部分升级后才能更新。我点击了“部分升级”选项，但没有成功。显示一条消息
之后我无法运行软件更新程序、Ubuntu 软件中心等。

我运行了上述命令两次，因为第一次无法获取数据。现在问题仍未解决，因为我仍然无法打开应用程序。

@IcyIcyIce 你能弄清楚问题是什么吗以及我现在该如何处理？
答案1
尝试运行命令sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade || sudo apt-get -f install。如果出现问题，则更新存储库，尝试更新，如果失败，则尝试修复损坏。
希望能帮助到你 ：）
