Ubuntu16.04解决问题：E: 无法获得锁 /var/lib/dpkg/lock-frontend - open (11: 资源暂时不可用)

在输入sudo apt-get update后发现终端提示：

E: 无法获得锁 /var/lib/dpkg/lock-frontend - open (11: 资源暂时不可用)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

• 解决方案一：

ps -e | grep apt

然后执行：sudo kill 进程号

 

• 解决方案二：

有一种情况是

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

但我遇到的情况是：E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it? 

sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock-frontend
