Ubuntu 14.04 即将结束支持，你该怎么办？
Ubuntu
Ubuntu 14.04 即将于 2019 年 4 月 30 日结束支持。这意味着在此日期之后 Ubuntu 14.04 用户将无法获得安全和维护更新。


你甚至不会获得已安装应用的更新，并且不手动修改 `sources.list` 则无法使用 `apt` 命令或软件中心安装新应用。


Ubuntu 14.04 大约在五年前发布。这是 Ubuntu 长期支持版本（LTS）。


[检查 Ubuntu 版本](https://itsfoss.com/how-to-know-ubuntu-unity-version/)并查看你是否仍在使用 Ubuntu 14.04。如果是桌面或服务器版，你可能想知道在这种情况下你应该怎么做。


我来帮助你。告诉你在这种情况下你有些什么选择。

### 升级到 Ubuntu 16.04 LTS（最简单的方式）


如果你可以连接互联网，你可以从 Ubuntu 14.04 升级到 Ubuntu 16.04 LTS。


Ubuntu 16.04 也是一个长期支持版本，它将支持到 2021 年 4 月。这意味着下次升级前你还有两年的时间。


我建议阅读这个[升级 Ubuntu 版本](https://itsfoss.com/upgrade-ubuntu-version/)的教程。它最初是为了将 Ubuntu 16.04 升级到 Ubuntu 18.04 而编写的，但这些步骤也适用于你的情况。


### 做好备份，全新安装 Ubuntu 18.04 LTS（非常适合桌面用户）


另一个选择是备份你的文档、音乐、图片、下载和其他任何你不想丢失数据的文件夹。


我说的备份指的是将这些文件夹复制到外部 USB 盘。换句话说，你应该有办法将数据复制回计算机，因为你将格式化你的系统。


我建议桌面用户使用此选项。Ubuntu 18.04 是目前的长期支持版本，它将至少在 2023 年 4 月之前得到支持。在你被迫进行下次升级之前，你将有四年的时间。


### 支付扩展安全维护费用并继续使用 Ubuntu 14.04


这适用于企业客户。Canonical 是 Ubuntu 的母公司，它提供 Ubuntu Advantage 计划，客户可以支付电话电子邮件支持和其他益处。


Ubuntu Advantage 计划用户还有[扩展安全维护](https://www.ubuntu.com/esm)（ESM）功能。即使给定版本的生命周期结束后，此计划也会提供安全更新。


这需要付出金钱。服务器用户每个物理节点每年花费 225 美元。对于桌面用户，价格为每年 150 美元。你可以在[此处](https://www.ubuntu.com/support/plans-and-pricing)了解 Ubuntu Advantage 计划的详细定价。


### 还在使用 Ubuntu 14.04 吗？


如果你还在使用 Ubuntu 14.04，那么你应该开始了解这些选择，因为你还有不到一个月的时间。


在任何情况下，你都不能在 2019 年 4 月 30 日之后使用 Ubuntu 14.04，因为你的系统由于缺乏安全更新而容易受到攻击。无法安装新应用将是一个额外的痛苦。


那么，你会做什么选择？升级到 Ubuntu 16.04 或 18.04 或付费 ESM？

OK
Ubuntu 14.04 reached its end of life on April 30, 2019. This means there will be no security and maintenance updates for Ubuntu 14.04 users anymore unless they pay for extended security (explained later).

You won’t even get updates for installed applications and you won’t be able to install a new application [using the apt command](https://itsfoss.com/apt-command-guide/) or the Software Center without manually modifying sources.list.

Ubuntu 14.04 was released almost five years ago. That’s the life of a long term support release of Ubuntu.

[Check your Ubuntu version](https://itsfoss.com/how-to-know-ubuntu-unity-version/) and see if you’re still using Ubuntu 14.04. If that’s the case for a desktop or a server you run, you might be wondering what you should do in such a situation.

Let me help you out there and tell you what options you have in this case.

![Ubuntu 14.04 End of Life](https://itsfoss.com/content/images/wordpress/2019/02/ubuntu-14-04-end-of-life-featured-800x450.png)

## Upgrade to Ubuntu 16.04 LTS (easiest of them all)

If you have a good internet connection, you can upgrade to Ubuntu 16.04 LTS from within Ubuntu 14.04.

Ubuntu 16.04 is also a [long term support release](https://itsfoss.com/long-term-support-lts/) and it will be supported till April, 2021. That means you’ll have two years before another upgrade.

I recommend reading this tutorial about [upgrading your Ubuntu version](https://itsfoss.com/upgrade-ubuntu-version/). It was originally written for upgrading Ubuntu 16.04 to Ubuntu 18.04 but the steps are applicable in your case as well.

## Make a backup, do a fresh install of Ubuntu 18.04 LTS (ideal for desktop users)

Another option is that you make a backup of your Documents, Music, Pictures, Downloads and any other folders where you have kept essential data that you cannot afford to lose.

When I say backup, I simply mean copying these folders to an external USB disk. In other words, you should have a way to copy the data back to your computer because you’ll be formatting your system.

I would recommend this option for desktop users. Ubuntu 18.04 is the current long term support release and it will be supported till at least April, 2023. You have four long years before you’ll be forced into another upgrade.

## Pay for extended security maintenance and continue using Ubuntu 14.04

This is suited to

Ubuntu Advantage program users also have the [Extended Security Maintenance](https://www.ubuntu.com/esm) (ESM) feature. This program provides security updates even after a given version reaches end of life.

This comes at a cost. It costs $225 per year per physical node for server users. For desktop users, the price is $150 per year. You can see detailed pricing for the Ubuntu Advantage program [here](https://www.ubuntu.com/support/plans-and-pricing).

## Still using Ubuntu 14.04?

If you’re still using Ubuntu 14.04, you should start exploring your options as you have less than two months to go.

In any case, you must not use Ubuntu 14.04 after 30 April 2019 because your system will be vulnerable due to the lack of security updates. Not being able to install new applications will be an additional major pain.

So which option will you choose here? Upgrading to Ubuntu 16.04 or 18.04 or paying for ESM?
