我安装了“axel”来从互联网上下载东西。所以我想删除“wget”。但是当我使用命令执行相同操作时
#sudo apt-get remove wget
它还删除了 Google Chrome。为什么会发生这种情况？
rana@Brahma:~$ sudo apt-get remove wget

下面是输出aptitude why google-chorme-stable wget：
rana@Brahma:~$ aptitude why google-chrome-stable wget
p google-chrome-stable Depends wget
答案1
嗯，原因很简单：
google-chrome-stable 依靠的wget。如果没有安装 wget，Google Chrome 也将被卸载，因为 Chrome 没有 wget 就无法工作（显然）。

如果要删除/清除 wget，google-chrome-stable 也将会按预期被删除。
