无法用KDE等离子体在Ubuntu 18.04上安装Latte-Dock

Question

我一直在尝试用KDE等离子体在Ubuntu上安装Latte，我一直在使用未满足的依赖项来获取错误。我试着删除旧的包，但这消除了整个KDE等离子体。有什么帮助吗？

Answer 1

我通过添加KUbuntu Backports并进行更新来修正这个问题。这更新了已经过时的一揽子计划。

sudo add-apt-repository ppa:kubuntu-ppa/backports

这通过KDE商店更新了所有包(许多)和已安装的Latte。

您应该尝试修复所有已损坏的包：

apt install -f
