error: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) Unable t

在ubuntu apt-get upgrade的时候，遇到：


ubuntu@ubuntu:/usr/src/XXXXXXXXXXX$ sudo apt-get install YYYYYYYY
[sudo] password for ubuntu: 


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?


解决办法如下：


sudo rm -rf /var/cache/apt/archives/lock
sudo apt-get update


然后apt-get就恢复正常了。


在执行sudo apt-get update的指令时，不要运行其它的程序sudo apt-get install 安装
