E: 无法获得锁 /var/lib/dpkg/lock-frontend - open (11: 资源暂时不可用)

今日使用Ubuntu系统的apt-get命令安装系统时发现不可用，提示其他进程正在占用

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
