ubuntu常见错误

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

出现这个问题可能是有另外一程序正在运行，导致资源被锁不可用。原因可能是上次运行安装或更新时没有正常完成，解决的办法：
在终端中敲入以下两句

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