E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

刚开始试了如下两个：

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

sudo rm /var/lib/dpkg/lock

发现没效果，然后有试了下面这组命令：

sudo rm /var/lib/dpkg/lock

sudo rm /var/lib/dpkg/lock

sudo dpkg --configure -a

然后就可以了，至于这些命令什么意思，不知道啊，都是网上搜来的
