我在Debian或者Ubuntu Linux下寻找yum groupinstall group之类的命令。
如何通过单个命令安装安装一组软件，例如DNS或者LAMP服务器？
您需要使用tasksel命令。
这是一个软件安装应用程序，是Debian安装程序不可或者缺的一部分，也可以在Ubuntu Linux下运行。
它按任务对某些软件包进行分组，并为用户提供了一种为该任务安装软件包的简便方法。
它提供了与使用常规元包相同的功能。

如何使用Taskel？

在Debian和Ubuntu Linux(自Ubuntu Edgy起)下，tasksel已作为基本安装的一部分包含在内。

taskel显示所有可用任务，并允许用户选择要安装的任务。
只需在shell提示符下以root用户身份执行taskel：

$ sudo tasksel

或者

# tasksel

根据发行版，您将看到软件选择菜单，如下所示：

按空格键，然后按确定按钮，选择所需的组。

如何在命令提示符下列出可用的组？

选项list-tasks在屏幕上列出了将在taskel TUI(文本用户界面)中显示的任务(程序包)。
您可以按以下方式使用它：

$ tasksel --list-tasks

输出示例：

是的，您不能忘记插入符号(^)。
您需要在包名称的末尾加上^；否则会产生如下错误：

E: Couldn't find package lamp-server
