Could not get lock /var/lib/dpkg/lock-frontend解决办法
一、问题描述：
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
二、解决办法： 解决，使用ps 和 grep查找apt的pid,并使用kill杀死掉。

然后就可以继续执行你的安装步骤了， 若是还出现问题则执行下面这行指令，手动删除 /var/lib/dpkg/lock
jack@ubuntu16:~$ sudo rm -rf /var/lib/dpkg/lock
