ubuntu服务器通过iso进行系统升级

1、添加iso文件源：

sudo mount -t iso9660 -o loop ubuntu-18.04.6-live-server-amd64.iso /media/cdrom
#挂在镜像文件到 /media/cdrom

sudo apt-cdrom -m add #添加挂载点镜像文件到更新源

#修改apt-get源，将光驱挂着的目录加入源
sudo vi /etc/apt/sources.list

1.查看unbuntu版本名
用以下命令查看版本名：
lsb_release -c
Ubuntu版本名与系统名对应关系
系统名 版本名
Ubuntu 20.10 groovy
Ubuntu20.04 focal
Ubuntu19.10 eoan
Ubuntu19.04 disco
Ubuntu18.04 bionic
Ubuntu16.04 xenial

2.备份原软件源

为了防止修改错误且找不到原来的软件源，将原来的软件源文件备份在相同文件夹下，使用命令：
sudo cp -v /etc/apt/sources.list /etc/apt/sources.list.backup

3.vim打开软件源文件

sudo vim /etc/apt/sources.list
按a进入追加模式，上下左右键控制光标，将原有内容删除或注释掉（在行首添加#） 复制对应版本的软件镜像源，在文件末尾粘贴（crtl+shift+v） 按esc退出编辑模式，输入:wq保存退出

4.对应版本软件源

Ubuntu20.10
