Ubuntu下控制台输入sudo apt-get update之后出现的问题：

E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable)

E: Unable to lock directory /var/lib/apt/lists/

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?

解决方法：

sudo rm /var/lib/apt/lists/lock

sudo rm /var/cache/apt/archives/lock

再试一次sudo apt-get update就可以了
