前期准备
- U盘制作启动项
- 将bios改成uefi启动,硬盘改成GPT(便于分多个主分区)
安装分区
- 均为主分区(对于是否保留boot分区,暂未查明确定说法)
- 另安装时将整块硬盘均安装为ubuntu,不涉及双系统


安装系统后附加
- 将“软件和更新”中Ubuntu软件下载至改成aliyun
- 换成国内最快的阿里云源
备份原来的源文件
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
替换源
sudo gedit /etc/apt/sources.list
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
