我最近安装了 Kubuntu 20.10，从昨天开始，每当我尝试从 Discover 中删除或安装某些东西时都会出现以下错误。
您无权执行此操作
下面是我尝试从 Konsole 执行它时的输出。

答案1
我通过在 Konsole 上运行以下命令修复了这个问题。
killall chrome-remote-desktop-host
后来，我从 Synaptics 中完全删除了 chrome-remote-desktop 包。我认为，如果尝试从 Konsole 中删除，以下命令也应该有效。
sudo apt remove chrome-remote-desktop
答案2
我修好了！在终端中以 root 身份运行 discover：
sudo plasma-discover
