电脑是 联想启天M
本机系统是win7 64位
想装ubuntu16.04双系统，在分区完要继续的时候，ubuntu好像提示过什么可能会出错
结果安装完的时候，登录不进桌面，tty1-6可以进



这里有一部分错误信息：
An error occurred while removing packages:

E:Sub-process /usr/bin/dpkg returned an error code (1)

The following packages are in a broken state:

This may be due to using an old installer image, or it may be due to a bug in some of the packages listed above. More details may be found in /var/log/syslog. The installer will try to continue anyway, but may fail at a later point, and will not be able to install or remove other packages (possibly including itself) from the installed system. You should first look for newer versions of your installer image, or failing that report the problem to your distributor.

有人能帮我解决吗？ 感激不尽

假設 你的問題是因為 未完整安裝 Ubuntu 圖形化 桌面環境 引起的

1. 登入 tty1
2. 把 tty7 關閉
2-1. sudo systemctl stop lightdm.service
或
2-2. sudo systemctl isolate multi-user.target
3. sudo apt-get install --reinstall ubuntu-desktop
4. sudo dpkg-reconfigure lightdm
5. sudo systemctl reboot
6. 如果有錯誤訊息 照相貼上來
