Error response from daemon: cannot stop container: ******: Cannot kill container *******:.....

停止Docker容器时出现：

Error response from daemon: cannot stop container: ******: Cannot kill container *******: unknown error after kill: runc did not terminate sucessfully: container_linux.go:392: signaling init process caused "permission denied"

解决办法：

sudo aa-remove-unknown

然后就可以正常停止容易了。
