在ubuntu16.04下安装git，出现以下问题：

E: Could not get@H_502_5@ lock@H_502_5@ /var@H_502_5@/lib/dpkg/lock@H_502_5@ - open (11@H_502_5@: Resource temporarily unavailable) 
E: Unable to lock@H_502_5@ the administration directory (/var@H_502_5@/lib/dpkg/)

解决方法：https://stackoverflow.com/questions/42899411/i-want-to-install-git-in-ubuntu-but-i-am-getting-error

sudo rm /var@H_502_5@/lib/apt/lists/lock@H_502_5@
sudo rm /var@H_502_5@/cache/apt/archives/lock@H_502_5@
sudo rm /var@H_502_5@/lib/dpkg/lock@H_502_5@
sudo dpkg --configure -a

原因可能是已经打开了Synaptic 包管理器的GUI界面，同时想通过在终端输入sudo apt-get install安装软件。
