记录在误删/var 文件夹之后，系统启动不能进入桌面系统的过程

1、首先进入命令行，

使用有线连接互联网

apt-get update

apt-get -f install 

apt-get install ubuntu-desktop 遇到问题，

问题:

我无法安装任何软件包，因为出现这里错误：

这里是这个问题的解决方案，超级容易

你必须直接使用dpkg来解决这个问题。

"又来了"

软件包 multiarch-support is unpacked, but has never been configured 这意味着包不久将配置，但还没有配置。

什么时候状态 unpacked 还没有安装，因此包 libgcc1 无法安装，因为依赖项还没有安装，并且无法安装在 multiarch-support 之前。

我们必须强制multiarch支持安装的状态来完成这个操作。

nano/var/lib/dpkg/status

　　查找以 Package: 开头的行，如下所示：

Package: multiarch-support


Status: install ok unpacked

　　

你必须将 unpacked 更改为 installed

现在尝试：

sudo dpkg --configure --pending


sudo apt-get install --reinstall multiarch-support libgcc1 debconf
