apt-get erro

1. 解决Could not get lock /var/cache/apt/archives/lock

在ubuntu apt-get upgrade的时候，遇到：

E: Could not get lock /var/cache/

apt/archives/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the download directory

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。

2. dpkg was interrupted

进入/var/lib/dpkg/updates目录，将该目录下的所有文件删掉，就可以修复cydia
