Ubuntu中Could not get lock /var/l

通过终端安装程序sudo apt-get install xxx时出错：
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?

出现此问题可能是因为apt正在运行，而导致此问题的原因可能是上次运行安装或更新时没有正常完成。

解决方案

在终端中敲入以下两句
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
