linux - 如何使用Trisquel安装Bumblebee？

Question

我试图在键入的Trisquel中安装大黄蜂

$ sudo apt-get install bumblebee

和输出

    Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package bumblebee is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'bumblebee' has no installation candidate

那么如何安装大黄蜂？
