Ubuntu出现"Could not get lock /var/lib/dpkg/lock"问题

今天在Ubuntu系统环境中，无论是执行update升级源软件的，还是进行其他软件安装的时候都有出现"Could not get lock /var/lib/dpkg/lock"的错误提示。

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

解决办法：

rm /var/cache/apt/archives/lock
rm /var/lib/dpkg/lock

删除两个文件，然后在apt-get update -y升级源之后执行需要操作的软件就解决问题。
