ubuntu无法进入桌面，安装ubuntu-desktop失败的解决办法

在执行windows远程连接ubuntu操作（安装 Xfce 和 Xrdp ）后，ubuntu在登录后无法进入桌面。

解决方法如下：

1.Ctrl+Alt+F1（或者F2-F8）进入命令行界面，登录账户

2.卸载Xwindows软件

sudo apt-get autoremove ubuntu-desktop

3.安装所有依赖软件

sudo apt-get update

sudo apt-get install ubuntu-desktop
4.重启 reboot

执行重装ubuntu-desktop前，可优先卸载引起该问题的软件
执行sudo apt install ubuntu-desktop时报错
