Debian和ubuntu apt-get 安装意外中断后导致资源被锁，及screen用法

错误提示：

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

解决办法：

sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
最后提醒安装前记得screen 一下！这样网络中断也可以接着运行
screen -S yourname -> 新建一个叫yourname的session
screen -ls -> 列出当前所有的session
screen -r yourname -> 回到yourname这个session
screen -d yourname -> 远程detach某个session
screen -d -r yourname -> 结束当前session并回到yourname这个session
