x64系统上安装32位库：sudo apt-get install libc6:i386时，弹出：
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?
解决方法：
1.Go to System => System Monitor
2.On the System Monitor go to the Processes
3.Go to view and then choose all processes
4.This will then display the the apt-get process
5.Just end the process and then voila you are good to go.
