[Ubuntu 19.04](https://itsfoss.com/ubuntu-19-04-release/) 发布于 2019 年 4 月 18 日。由于它不是长期支持（LTS）版本，因此只有 9 个月的支持。完成它的发行周期后，Ubuntu 19.04 于 2020 年 1 月 23 日到期。


Ubuntu 19.04 带来了一些视觉和性能方面的改进，为时尚和美观的 Ubuntu 外观铺平了道路。与其他常规 Ubuntu 版本一样，它的生命周期为 9 个月。它如今结束了。


### Ubuntu 19.04 终止了吗？这是什么意思？


EOL（End of life）是指在某个日期之后操作系统版本将无法获得更新。你可能已经知道 Ubuntu（或其他操作系统）提供了安全性和维护升级，以使你的系统免受网络攻击。当发行版到期后，操作系统将停止接收这些重要更新。


如果你的操作系统版本到期后继续使用该系统，那么系统将容易受到网络和恶意软件的攻击。不仅如此。在 Ubuntu 中，你使用 APT 从软件中心下载的应用也不会更新。实际上，你将不再能够[使用 apt-get 命令安装新软件](https://itsfoss.com/apt-get-linux-guide/)（如果不是立即，那就是逐渐地）。


### 所有 Ubuntu 19.04 用户必须升级到 Ubuntu 19.10


从 2020 年 1 月 23 日开始，Ubuntu 19.04 将停止接收更新。你必须升级到 2020 年 7 月之前受支持的 Ubuntu 19.10。这也适用于其他[官方 Ubuntu 衍生版](https://itsfoss.com/which-ubuntu-install/)，例如 Lubuntu、Xubuntu、Kubuntu 等。


你可以在“设置 -> 细节” 或使用如下命令来[检查你的 Ubuntu 版本](https://itsfoss.com/how-to-know-ubuntu-unity-version/)：



```
lsb_release -a
```

#### 如何升级到 Ubuntu 19.10？


值得庆幸的是，Ubuntu 提供了简单的方法来将现有系统升级到新版本。实际上，Ubuntu 还会提示你有新的 Ubuntu 版本可用，你应该升级到该版本。

如果你的互联网连接良好，那么可以使用[和更新 Ubuntu 一样的 Software Updater 工具](https://itsfoss.com/update-ubuntu/)。在上图中，你只需单击 “Upgrade” 按钮并按照说明进行操作。我已经编写了有关使用此方法[升级到 Ubuntu 18.04](https://itsfoss.com/upgrade-ubuntu-version/)的文章。


如果你没有良好的互联网连接，那么有一种临时方案。在外部磁盘上备份家目录或重要数据。


然后，制作一个 Ubuntu 19.10 的 Live USB。下载 Ubuntu 19.10 ISO，并使用 Ubuntu 系统上已安装的启动磁盘创建器从该 ISO 创建 Live USB。


从该 Live USB 引导，然后继续“安装” Ubuntu 19.10。在安装过程中，你应该看到一个删除 Ubuntu 19.04 并将其替换为 Ubuntu 19.10 的选项。选择此选项，然后像重新[安装 Ubuntu](https://itsfoss.com/install-ubuntu/)一样进行下去。


#### 你是否仍在使用 Ubuntu 19.04、18.10、17.10 或其他不受支持的版本？


你应该注意，目前仅 Ubuntu 16.04、18.04 和 19.10（或更高版本）版本还受支持。如果你运行的不是这些 Ubuntu 版本，那么你必须升级到较新版本。

**Brief: Ubuntu 19.04 has reached the end of life on 23rd January 2020. This means that systems running Ubuntu 19.04 won’t receive security and maintenance updates anymore and thus leaving them vulnerable.**

![End Of Life Ubuntu 19.04](https://itsfoss.com/content/images/wordpress/2020/02/End-of-Life-Ubuntu-19.04.png)

[Ubuntu 19.04](https://itsfoss.com/ubuntu-19-04-release/) was released on 18th April, 2019. Since it was not a long term support (LTS) release, it was supported only for nine months.

Completing its release cycle, Ubuntu 19.04 reached end of life on 23rd January, 2020.

Ubuntu 19.04 brought a few visual and performance improvements and paved the way for a sleek and aesthetically pleasant Ubuntu look.

Like any other regular Ubuntu release, it had a life span of nine months. And that has ended now.

## End of life for Ubuntu 19.04? What does it mean?

End of life is means a certain date after which an operating system release won’t get updates.

You might already know that Ubuntu (or any other operating system for that matter) provides security and maintenance upgrades in order to keep your systems safe from cyber attacks.

Once a release reaches the end of life, the operating system stops receiving these important updates.

If you continue using a system after the end of life of your operating system release, your system will be vulnerable to cyber attacks and malware.

That’s not it. In Ubuntu, the applications that you downloaded using APT from Software Center won’t be updated as well. In fact, you won’t be able to [install new software using apt-get command](https://itsfoss.com/apt-get-linux-guide/) anymore (gradually, if not immediately).

## All Ubuntu 19.04 users must upgrade to Ubuntu 19.10

Starting 23rd January 2020, Ubuntu 19.04 will stop receiving updates. You must upgrade to Ubuntu 19.10 which will be supported till July 2020. This is also applicable to other [official Ubuntu flavors](https://itsfoss.com/which-ubuntu-install/) such as Lubuntu, Xubuntu, Kubuntu etc.

You can [check the Ubuntu version](https://itsfoss.com/how-to-know-ubuntu-unity-version/) either from the settings->Details or by using the command:

`lsb_release -a`


### How to upgrade to Ubuntu 19.10?

Thankfully, Ubuntu provides easy ways to upgrade the existing system to a newer version.

In fact, Ubuntu also prompts you that a new Ubuntu version is available and that you should upgrade to it.

![Ubuntu 19 04 End Of Life](https://itsfoss.com/content/images/wordpress/2020/02/ubuntu_19_04_end_of_life.jpg)

If you have a good internet connection, you can use the same [Software Updater tool that you use to update Ubuntu](https://itsfoss.com/update-ubuntu/). In the above image, you just need to click the Upgrade button and follow the instructions. I have written a detailed guide about [upgrading to Ubuntu 18.04](https://itsfoss.com/upgrade-ubuntu-version/) using this method.

If you don’t have a good internet connection, there is a workaround for you. Make a backup of your home directory or your important data on an external disk.

Then, make a live USB of Ubuntu 19.10. Download Ubuntu 19.10 ISO and use the Startup Disk Creator tool already installed on your Ubuntu system to create a live USB out of this ISO.

Boot from this live USB and go on ‘installing’ Ubuntu 19.10. In the installation procedure, you should see an option to remove Ubuntu 19.04 and replace it with Ubuntu 19.10. Choose this option and proceed as if you are [installing Ubuntu](https://itsfoss.com/install-ubuntu/) afresh.

### Are you still using Ubuntu 19.04, 18.10, 17.10 or some other unsupported version?

You should note that at present only Ubuntu 16.04, 18.04 and 19.10 (or higher) versions are supported. If you are running an Ubuntu version other than these, you must upgrade to a newer version.
