Sudo apt-get 错误：/var/lib/dpkg/status 上的 flAbsPath 失败 - 没有这样的文件或目录

Question

sudo apt-get install vlc
Reading package lists... Error!
E: flAbsPath on /var/lib/dpkg/status failed - realpath (2: No such file or directory)
E: Could not open file  - open (2: No such file or directory)
E: Problem opening 
E: The package lists or status file could not be parsed or opened.

每当我尝试安装任何软件时，都会出现此错误。我该如何解决这个问题？

Answer 1

我最近在使用 ubuntu 16.04.3 LTS 时遇到了类似的问题，对我有用的方法如下 -

首先，您需要创建一个空文件，如下所示：-

adminuser@sandbox:~$ sudo touch /var/lib/dpkg/status

现在运行更新和升级：-

adminuser@sandbox:~$ sudo apt update && sudo apt upgrade

很可能你最终会看到这样的东西——

adminuser@sandbox:~$ sudo apt update

但是，如果您注销并重新登录，您的 MOTD 会显示一些更新正在等待中 -

Welcome to Ubuntu 16.04.3 LTS (GNU/Linux 4.4.0-96-generic x86_64)

 * Documentation:  https://help.ubuntu.com
 * Management:     https://landscape.canonical.com
 * Support:        https://ubuntu.com/advantage

108 packages can be updated.
27 updates are security updates.

此时，你需要运行 dist-upgrade -

adminuser@sandbox:~$ sudo apt dist-upgrade

这应该可以解决问题，但请确保它不会促使您将 Ubuntu 实际升级到新版本。据我所知，在 Ubuntu 18.04 LTS 发布之前，这应该可以工作。祝你好运

第 1 步：cd /

第二步：cd var/lib/

第 3 步：mkdir dpkg

第四步：触摸状态

这对我有用。:)

Answer 3

您必须重新创建 /var/lib/dpkg 文件结构，这确实需要备份或运气（也许两者都需要）。看这里。
