ubuntu问题: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailabl

问题：

root@in2:/home# apt-get install git
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

解决方案：
1.root@in:/home# ps -A |grep apt
 4019 pts/12   00:00:03 apt-get
root@in:/home# kill -9 4019
root@in:/home# sudo apt-get install mplayer
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 
root@in:/home# dpkg --configure -a

2.报错原因其实这是因为有另外一个程序在运行，导致锁不可用。原因可能是上次运行更新或安装没有正常完成。解决办法是杀死此进程。
PS -A |grep apt 无显示进程
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock

可能还会出现问题，解决方案：
sudo dpkg --configure -a
sudo apt-get update

问题：

  dpkg: error: dpkg frontend is locked by another process

原因是包管理器没有正确关闭。需要重启计算机或者重新打开终端 输入：

sudo rm /var/lib/dpkg/lock

sudo dpkg --configure -a
