linux上apt-get,出现“E: Could not get lock /var/cache/apt/archives/lock - open ...”

在ubuntu 上apt-get更新python版本时，提示：
E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/cache/apt/archives/

原因： 锁被占用，资源暂时不可用

解决方法：

sudo rm -rf /var/cache/apt/archives/lock
sudo apt-get update

之后再安装即可
