Google Compute Engine VM上的Ubuntu do-release-upgrade [英] Ubuntu do-release-upgrade on Google Compute Engine VM

问题描述

我可以运行do-release-upgrade来升级我的Ubuntu Google Compute Engine VM吗?

Can I run the do-release-upgrade to upgrade my Ubuntu Google Compute Engine VM?

VM映像版本为Ubuntu 14.04. 我想升级到Ubuntu 16.04或18.04.

The VM image version is Ubuntu 14.04 now. And I would like to upgrade to Ubuntu 16.04 or 18.04.

推荐答案

是的，并且按照以下文档也是首选方式，因为

Yes you can, and as per the following document is also the preferred way because,

ubuntu-release-upgradeer 软件包，提供do-release-upgrade，旨在处理在Ubuntu版本之间移动时的怪癖和过渡.

The ubuntu-release-upgrader package, provides do-release-upgrade, and is designed to handle quirks and transitions when moving between releases of Ubuntu.

这是因为Ubuntu开发人员不支持Debian方式.

This is because the Debian way is not supported by the Ubuntu developers.

如果遵循正确的步骤，则会看到类似以下消息:

If you followed the right steps, you will see a message similar to this:

System upgrade is complete.

Restart required 

To finish the upgrade, a restart is required. 
If you select 'y' the system will be restarted.

在Google图片文档页面中解释说，

In the Google images document page it explaines that,

如果您的实例运行不再受支持的Ubuntu版本，则可以升级到受支持的Ubuntu版本.

If your instances run Ubuntu releases that are no longer supported,you are allowed to upgrade to a supported Ubuntu release.

还有另一件事，如@Martin所述.在升级映像版本之前，先创建磁盘快照始终是一个好主意.如果您不熟悉do-release-upgrade的完整过程，请执行以下
