Ubuntu 19.10 Reaches End of Life. Upgrade to Ubuntu 20.04 As Soon As Possible!
|
||||
======
|
||||
|
||||
_**Ubuntu 19.10 Eoan Ermine**_ _**has reached end of life. That it means it won’t get any security or maintenance updates. Continue using Ubuntu 19.10 would be risky as your system may be vulnerable in future for the lack of security updates. You should upgrade to Ubuntu 20.04.**_
|
||||
|
||||
[Ubuntu 19.10 was released in October 2019][1] bringing some new features that prepared a base for [Ubuntu 20.04][2].
|
||||
|
||||
As a non-LTS release, it had a lifespan of nine months. It has completed its life cycle and as of 17th July 2020, it won’t be getting any updates.
|
||||
|
||||
### End of life for Ubuntu 19.10
|
||||
|
||||
![][3]
|
||||
|
||||
I have [explained Ubuntu release cycle and end of life][4] in detail earlier. I’ll reiterate what it means to you and your system if continue using Ubuntu 19.10 beyond this point.
|
||||
|
||||
[Software usually hav][5][e][5] [a predefined life cycle][5] and once a software version reaches end of life, it stops getting updates and support.
|
||||
|
||||
Beyond the end of life, Ubuntu 19.10 won’t get system updates, security updates or application updates from Ubuntu anymore.
|
||||
|
||||
If you continue using it, your system may fell victim to potential cyberattacks as hackers tend to exploit vulnerable system.
|
||||
|
||||
Later, you might not be able to install new software using apt command as Ubuntu will archive the repository for 19.10.
|
||||
|
||||
### What to do if you are using Ubuntu 19.10?
|
||||
|
||||
First, [check which version of Ubuntu you are using][6]. This can be done quickly by entering this command in the terminal:
|
||||
|
||||
```
|
||||
lsb_release -a
|
||||
```
|
||||
|
||||
```
|
||||
No LSB modules are available.
|
||||
Distributor ID: Ubuntu
|
||||
Description: Ubuntu 19.10
|
||||
Release: 19.10
|
||||
Codename: Eoan
|
||||
```
|
||||
|
||||
If you see Ubuntu 19.10, you should do either of these two things:
|
||||
|
||||
* If you have a good speed, consistent internet connection, upgrade to Ubuntu 20.04 from within 19.10. Your personal files and most software remain untouched.
|
||||
* If you have a slow or inconsistent internet connection, you should do a [fresh installation of Ubuntu 20.04][7]. Your files and everything else on the disk will be erased so you should make backup of your important data on an external disk.
|
||||
|
||||
|
||||
|
||||
#### How to upgrade to Ubuntu 20.04 from 19.10 (if you have good internet connection)
|
||||
|
||||
I have discussed the Ubuntu version upgrade in details previously. I’ll quickly mention the steps here as well.
|
||||
|
||||
First, make sure that your system is set to be notified of new version in Software & Updates.
|
||||
|
||||
Go to Software & Updates:
|
||||
|
||||
![][8]
|
||||
|
||||
Go to Updates tab and set “Notify me of a new Ubuntu version” to “For any new version”:
|
||||
|
||||
![][9]
|
||||
|
||||
Now, install any pending updates.
|
||||
|
||||
Now, run Update Manager tool again. You should be given the option to upgrade to Ubuntu 20.04. Hit the upgrade button and follow the instructions.
|
||||
|
||||
It installs packages of around 1.2 GB. This is why you need a good and consistent internet connection.
|
||||
|
||||
![][10]
|
||||
|
||||
Upgrading this way keeps your home directory as it is. Having a backup on external disk is still suggested, though.
|
||||
|
||||
### Are you still using Ubuntu 19.10?
|
||||
|
||||
If you are still using Ubuntu 19.10, you must prepare for the upgrade or fresh installation. You must not ignore it.
|
||||
|
||||
If you don’t like frequent version upgrades like this, you should stick with LTS versions that are supported for five years. The current LTS version is Ubuntu 20.04 which you’ll be upgrading to anyway.
|
||||
|
||||
Were/are you using Ubuntu 19.10? Have you already upgraded to Ubuntu 20.04? Let me know if you face any issue or if you have any questions.

Ubuntu 19.10 产品寿命结束。尽快升级到 Ubuntu 20.04！
|
||||
======
|
||||
|
||||
_**Ubuntu 19.10 Eoan Ermine 产品寿命结束。这意味着它不会获得任何安全或维护更新。继续使用 Ubuntu 19.10 将很危险，因为你的系统将来可能会因为缺少安全更新而变得脆弱。你应该升级到 Ubuntu 20.04。**_
|
||||
|
||||
[2019 年 10 月发布的 Ubuntu 19.10][1] 带来了一些为 [Ubuntu 20.04][2] 做准备的新功能。
|
||||
|
||||
作为非 LTS 版本，它有 9 个月的寿命。截至 2020 年 7 月 17 日，它的生命周期结束，并不会再收到任何更新。
|
||||
|
||||
### Ubuntu 19.10 生命周期结束
|
||||
|
||||
![][3]
|
||||
|
||||
我之前已经[详细解释了 Ubuntu 的发布周期和产品寿命结束][4]。如果此后继续使用 Ubuntu 19.10，我会重申这对你和你的系统意味着什么。
|
||||
|
||||
[软件通常有预定义的生命周期][5]，一旦软件版本到达生命周期结束，它将停止获取更新和支持。
|
||||
|
||||
生命周期结束后，Ubuntu 19.10 不再会从 Ubuntu 获得系统更新、安全更新或应用更新。
|
||||
|
||||
如果你继续使用它，你的系统可能会成为潜在的网络攻击的受害者，因为黑客往往会利用脆弱的系统。
|
||||
|
||||
之后，你可能无法使用 apt 命令安装新软件，因为 Ubuntu 将归档 19.10 的仓库。
|
||||
|
||||
### 如果你使用的是 Ubuntu 19.10，该怎么办？
|
||||
|
||||
首先，[检查你使用的 Ubuntu 版本][6]。这可以在终端中输入此命令完成：
|
||||
|
||||
```
|
||||
lsb_release -a
|
||||
```
|
||||
|
||||
```
|
||||
No LSB modules are available.
|
||||
Distributor ID: Ubuntu
|
||||
Description: Ubuntu 19.10
|
||||
Release: 19.10
|
||||
Codename: Eoan
|
||||
```
|
||||
|
||||
如果你看到 Ubuntu 19.10，你应该做以下两项工作之一：
|
||||
|
||||
* 如果你有良好，稳定的互联网连接，从 Ubuntu 19.10 升级到 20.04。你的个人文件和大多数软件保持不变。
|
||||
* 如果你有着缓慢或不稳定的互联网连接，你应该[全新安装的 Ubuntu 20.04][7]。你的文件和磁盘上的所有内容将被擦除，因此你应该在外部磁盘上备份重要数据。
|
||||
|
||||
|
||||
#### 如何从 19.10 升级到 20.04 （如果你有良好的互联网连接）
|
||||
|
||||
我之前已经详细讨论了 Ubuntu 版本升级。我会在这里快速说下步骤。
|
||||
|
||||
首先，请确保在“软件和更新”中已设置接收新版本通知。
|
||||
|
||||
进入“软件和更新”：
|
||||
|
||||
![][8]
|
||||
|
||||
进入“更新”选项卡，将“通知我新的 Ubuntu 版本”设置为“对于任何新版本”：
|
||||
|
||||
![][9]
|
||||
|
||||
现在，安装所有挂起的更新。
|
||||
|
||||
现在，再次运行更新管理器工具。你应该可以选择升级到 Ubuntu 20.04。点击升级按钮并按照说明操作。
|
||||
|
||||
它会安装大约 1.2GB 的软件包。这就是为什么你需要一个良好和稳定的互联网连接。
|
||||
|
||||
![][10]
|
||||
|
||||
这样升级会保持你的家目录。不过，仍建议在外部磁盘进行备份。
|
||||
|
||||
### 你仍在使用 Ubuntu 19.10 吗？
|
||||
|
||||
如果你仍在使用 Ubuntu 19.10，那么必须为升级或全新安装做好准备。你不能忽视它。
|
||||
|
||||
如果你不喜欢这样的频繁版本升级，你应该使用支持五年的 LTS 版本。当前的 LTS 版本是 Ubuntu 20.04，你无论如何都要升级到它。
|
||||
|
||||
你是否正在使用 Ubuntu 19.10？你是否已升级到 Ubuntu 20.04？如果你面临任何问题，或者如果你有任何问题，请让我知道。
