apt-get 安装包报错如下．
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
sudo apt-get install
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
上次执行apt-get更新时意外中断导致以上结果，解决方案如下
sudo rm /var/lib/dpkg/lock-frontend
sudo rm /var/lib/dpkg/lock
再次执行sudo apt-get install 命令即可
