更新后KDE Neon Ubuntu坠毁

Question

在尝试更新到Ubuntu18.04之后，我遇到了一个问题。当我重新启动我的系统时，Ubuntu以终端模式启动。我想在不重新安装操作系统的情况下修复这个问题。我试图从grub恢复模式启动，但没有帮助。

然后我尝试键入命令，这些命令显示为这里。运行此命令后出现了一个错误。

dpkg --configure -a

下面是它们：

dpkg: error processing package neon-desktop (--configure)
dependencies problem - leaving unconfigured

我试图运行sudo apt-get install --reinstall neon-desktop，但是我得到了以下未满足的依赖项错误。

sudo apt install --reinstall neon-desktop

You might want to run 'apt --fix-broken install' to correct these.

任何升级到一个新的Ubuntu版本，第三方存储库和ppa的将被禁用。您需要检查它们是否支持新版本(在您的例子中是bionic)，并将它们更改为新版本。然后你可以重新启用它们。

在sources.list文件中查找KDE存储库的相关条目

应该是这样的：

# deb http://archive.neon.kde.org/user xenial main 

取决于您如何安装它，您可以在/etc/apt/sources.list中找到它，或者(更可能)在/etc/apt/sources.list.d/中的一个文件中找到它。

还可以使用以下命令查找该文件：

grep -rlF 'archive.neon.kde.org' /etc/apt/

将xenial更改为bionic，并通过从该行中删除#来重新启用存储库。

然后跑：

sudo apt-get update
sudo apt-get install -f
