回退Ubuntu记录

前言

由于Ubuntu18经常出错，因而决定回退Ubuntu16，下面是记录回退问题及美化，以便以后需要。

问题总结

磁盘挂载

挂载其他磁盘分区时，提示错误“Metadata kept in Windows cache, refused to mount.”，执行下面命令即可修复。

sudo ntfsfix /dev/sdad

若是提示错误“Windows is hibernated, refused to mount.”，则关闭Windows的快速启动。

双系统时间不一致

Windows与Ubuntu的时间不一样，执下面的命令即可。

sudo timedatectl set-local-rtc 1

安装chrome

sudo wget http://www.linuxidc.com/files/repo/google-chrome.list -P /etc/apt/sources.list.d/
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub  | sudo apt-key add -
sudo apt update
sudo apt install google-chrome-stable

更换APT源

修改文件/etc/apt/sources.list为下面内容，以更换为阿里的源。
