apt-get update

 如果不能update则执行

apt-get install -f apt

安装轻量级桌面xfce[优先选择]
apt-get install xubuntu-desktop

如果你只想安装必要的桌面管理软件而不想安装一些诸如 Evolution 和 OpenOffice 的不需要的应用软件，可使用下面的命令：
apt-get install --no-install-recommends ubuntu-desktop

安装 KDE 桌面，使用下面的命令：
sudo apt-get install kubuntu-desktop

我绝大多数情况下不用GUI界面，所以桌面我不擅长。

常用命令软件的安装

apt install -y sysstat
