当前一个 dpkg 安装操作尚未完成时异常退出，导致重新安装时，报错：

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?

参考：https://www.cnblogs.com/dakewei/p/10491278.html

删除即可：

sudo rm /var/lib/dpkg/lock-frontend && sudo rm /var/lib/dpkg/lock

然后继续，报错：

E: Could not get lock /var/cache/apt/archives/lock - open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/cache/apt/archives/

删除即可：

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