删除锁定文件

锁定的文件会阻止 Linux 系统中某些文件或者数据的访问，这个概念也存在于 Windows 或者其他的操作系统中。

4 }9 G$ s3 [/ j一旦你运行了 apt-get 或者 apt 命令，锁定文件将会创建于 /var/lib/apt/lists/、/var/lib/dpkg/、/var/cache/apt/archives/ 中。* u1 x! A; H" v% {* y( H

这有助于运行中的 apt-get 或者 apt 进程能够避免被其它需要使用相同文件的用户或者系统进程所打断。当该进程执行完毕后，锁定文件将会删除。2 U! E% R5 Q" [9 x/ _! V! q
