1.下载安装systemback

# 1）删除ppa
sudo add-apt-repository ppa:nemh/systemback

以下是执行命令之后的输出结果：（出现E:这个错误不要着急，先执行下一个命令）

# 2）在18.04上添加Ubuntu 16.04 PPA
在Ubuntu16.04的Systemback binary包可以兼容Ubuntu18.04，因此，可以将Ubuntu16.04的PPA添加到系统

sudo add-apt-repository "deb http://ppa.launchpad.net/nemh/systemback/ubuntu xenial main"

# 3）导入此PPA的GPG签名密钥，以便包管理器可以验证签名
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 382003C2C8B7B4AB813E915B14E4942973C62A1B

该图片为2.3命令输出结果，这里为正常的，不需要停留，直接执行接下来的命令

# 4）更新包列表并安装Systemback：
sudo apt update
sudo apt install systemback

# 5）启动 Systemback
sudo systemback

该图片为执行4之后最终的效果

2.打包自己的系统

1.启动systemback
有两种方法
a.在命令行执行sudo systemback
b.在show applications搜索systemback 如下图所示

2.进入需要输入密码，然后点击ok

3.点击live system create

4.设置工作路径和活动系统名（输出文件路径和输出文件名）后点击Create new按钮

5：等待处理完成，home目录下面会有一个sblive文件生成

3.制作iso镜像

1.选中上一步生成的sblive文件，点击转换按钮开始转换

这里需要注意，你选自的sblive文件是否超过了4G，因为超过4G的中间还需要其他操作解决这个问题，可以看链接中2.1和2.2的操作

2：等待转换完成后，在 /home目录下就会生成一个ISO文件

3.检查是否存在

还记得我们之前的工作目录是/home 吗，这个镜像文件就在这个目录下

4.你可以通过共享文件夹，把他移动到你的主机上去，之后再使用他去安装虚拟机

5.安装ubuntu

1.我使用的是virtualbox,点击新建

2.还是根据新建步骤来，只是添加自己制作的iso就可以了

3,进入到新系统里，再打开systemback

4,这个时候你会发现，你需要填写新的用户名
这里建议你填写原本的，系统是可以直接运行之前配置好的环境的
如果是新的用户名，可能要重新创建工作空间进行编译

5.这里要为系统切割分区
本来就是虚拟机就不用区分了，并且再install GRUB2 bootloader 引导程序默认为auto就行
记住要勾选transfer user configuration files 和format
=======================================

systemback的下载安装参考了1.2和2.2

当你生成的.sblive文件大于4GB时，请参考
2.1和2.2和2.4

以下为参考文档

1.仅安装systemback,将自己的系统制作为iso
