Sorry for english,but I don't know how to install back up for Chinese spelling.
Below is the problem I encountered when I click "apply" after choosing the package I want to install.

E: 无法获得锁 /var/cache/apt/archives/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the download directory

不要同时打开两个及以上的包管理进程

关掉多的包管理进程，只能 同时最多开一个，包括 添加删除－终端安装－新立得

重启后就可以使用了。
