我试图在 ubuntu 中安装无线工具
sudo apt-get install wireless-tools
当我按下回车键时它显示如下
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package wireless-tools 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 'wireless-tools' has no installation candidate
帮我解决这个问题
