如何在AWS上将ubuntu节点从12.11降级到12.04 LTS？
[英]How to downgrade ubuntu node from 12.11 to 12.04 LTS on aws?
问题描述
Our node initially was running with ubuntu 12.04 LTS on aws. 
我们的节点最初在AWS上运行ubuntu 12.04 LTS。 But somehow the OS was bumped up to 12.11 (on development branch) by itself. 但是，操作系统本身以某种方式提升到了12.11（在开发部门）。 How can we downgrade the node to back to ubuntu 12.04 LTS and keep the OS for as long as we like? 我们如何将节点降级回ubuntu 12.04 LTS，并在需要的情况下将操作系统保留尽可能长的时间？
Is there a configuration on aws console that allows us to change OS version? AWS控制台上是否有允许我们更改操作系统版本的配置？ Thanks for the help. 谢谢您的帮助。

Ubuntu is not designed for roll backs. Ubuntu不适用于回滚。 If you are on the LTS branch and your sources.list file has not been altered and dist-upgrade has not been run, there should be no reason for the system to upgrade. 如果您位于LTS分支上，并且您的sources.list文件尚未更改，并且尚未运行dist-upgrade ，则应该没有理由升级系统。
Your best route is to create a new instance or, if you've created a snapshot (with EBS) recovering from it. 最好的方法是创建一个新实例，或者如果已创建快照（使用EBS）从中恢复。
