如何现在就升级到 Ubuntu 21.10
Ubuntu
[Ubuntu 21.10 “Impish Indri” 刚刚发布](/article-13887-1.html)。如果你正在使用 Ubuntu 21.04，你应该有升级到 Ubuntu 21.10 的选项。

然而，这种推出将是逐步的。这意味着不是每个人都会立即得到新版本可用的通知。在你看到升级选项之前，可能需要几周的时间。


但是，如果你迫不及待地想获得带有 GNOME 40 和其他新功能的 Ubuntu 21.10 呢？你真的需要等待吗？不用。


### 现在就从 Ubuntu 21.04 升级到 Ubuntu 21.10


以下是你要做的。打开“<ruby> 软件和更新 <rt>  Software &amp; Updates </rt></ruby>”应用：


![Start the Software & Updates application](/data/attachment/album/202110/20/105106s1ulasqtj7alaqzz.jpg)


并确保你在“<ruby> 更新 <rt>  Updates </rt></ruby>”标签下将“<ruby> 通知我新的 Ubuntu 版本 <rt>  Notify me of a new Ubuntu version </rt></ruby>”设置为“<ruby> 任何新版本 <rt>  For any new version </rt></ruby>”。


![Make sure that settings are right for new Ubuntu version notification](/data/attachment/album/202110/20/105107ia447cb4vub5cy3q.jpg)


现在打开终端，输入以下命令，以确保你的系统已经更新：



```
sudo apt update && sudo apt upgrade

```

当你的 Ubuntu 21.04 系统安装了所有的更新，运行更新管理器来寻找开发版本（本例中为 Ubuntu 21.10）。



```
update-manager -d

```

它将打开寻找更新的“<ruby> 更新管理器 <rt>  Update Manager </rt></ruby>”。由于你已经更新了系统，它不会找到新的更新来安装。然而，它将看到 Ubuntu 21.10 现在已经可用。


![Hit the upgrade button](/data/attachment/album/202110/20/105107juds9v97sv67u7k7.jpg)


你可以点击“<ruby> 升级 <rt>  Upgrade </rt></ruby>”按钮，按照屏幕上的选项开始升级程序。你需要有良好的网络速度来下载 2GB 的更新。确保你的系统在升级过程中保持与电源的连接。


享受 Ubuntu 21.10！

Ubuntu 24.04 LTS is here. If you are using Ubuntu 22.04 Long-term support release, you will not be immediately notified of this release. It might take a bit of time.

However, you can choose to upgrade your system to Ubuntu 24.04 LTS right now.

In either case, if you are using Ubuntu 23.10, you can upgrade to the latest LTS release as well.

No matter what you have now, if you want to get your hands on Ubuntu 24.04 LTS that [comes with GNOME 46](https://news.itsfoss.com/gnome-46-release/) and other new features, you no longer have to wait.

You can easily upgrade your system to Ubuntu 24.04 LTS right now.

Once you upgrade, you cannot go back to the previous version. You’ll have to freshly install it.

## Upgrading to Ubuntu 24.04 LTS from Ubuntu 23.10 Right Now

[make a backup of your data](https://itsfoss.com/backup-restore-linux-timeshift/)on an external disk. Having a

[live Ubuntu USB](https://itsfoss.com/intsall-ubuntu-on-usb/)helps you reinstall in some rare unfortunate incidents when the upgrade doesn’t go as planned.

Here, I assume that you are using Ubuntu 23.04 and want to upgrade. You can check what Ubuntu version you have using the following command in the terminal:

`lsb_release -a`


Here's the output you will see:

```
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 23.10
Release: 23.10
Codename: mantic
```


Here’s what you do. Open the Software & Updates application:

![Software and Updates app in Ubuntu Activities Overview](https://itsfoss.com/content/images/2023/10/2-Software-and-updates-app-in-Ubuntu-activities-overview.png)

And make sure that you have set “Notify me of a new Ubuntu version” to “For any new version” under the Updates tab. This should be the case if you are using Ubuntu 23.10 in the first place.

![Select "For any new version" for Update notification in Software and Updates Application](https://itsfoss.com/content/images/2023/10/3-update-tab-for-any-new-version.png)

Now open a terminal and enter the following command to make sure that your system is updated:

`sudo apt update && sudo apt upgrade`


Now run the Software Updater, and it should show you the option to upgrade to Ubuntu 24.04 LTS.

![Software Updater in Ubuntu Activities Overview](https://itsfoss.com/content/images/2023/10/4-run-software-updater-from-activities-overview.png)

## Still don’t see the upgrade?

![Software Up-to-date notification shown by Software Updater Application](https://itsfoss.com/content/images/2023/10/software-up-to-date-1.png)

If you do not see the upgrade notification, you can still force it to find it for you.

You can make the update manager to look for development releases (Ubuntu 23.10 in this case) with this command:

`update-manager -d`


It will open the Update Manager tool that looks for updates. Since you have already updated the system, it won’t find new updates to install. However, it will see that Ubuntu 24.04 LTS is now available.

You can hit the upgrade button and follow the on-screen option to start the upgrade procedure.

![ubuntu 24.04 upgrade](https://itsfoss.com/content/images/2024/04/ubuntu24-04-upgrade.png)

Ensure these two things:

**You should have a good internet speed to download the update (~2 GB or more).****Your system should stay connected to a power source during the upgrade.**

The upgrade starts like this:

![ubuntu 24.04 upgrade process](https://itsfoss.com/content/images/2024/04/ubuntu-24-04-upgrade-process.png)

The next step shows you that the third-party PPAs will be disabled (so you will have to **manually enable them after the upgrade if needed**)

![Third-party sources are disabled during upgrade](https://itsfoss.com/content/images/2024/04/ppa-disabled-24-04.png)

It will then prompt you to show the number of new packages to be installed and the ones that are no longer needed:

![Click on "Start Upgrade" button after cchecking the details, to start Upgrade process](https://itsfoss.com/content/images/2024/04/24-04-upgrade-changes.png)

Hit “**Start Upgrade**” to continue with the upgrade process. The system will disable the lock screen during the upgrade process, and you will be notified of the same. Click Close.

![Lock Screen Disabled during the Update](https://itsfoss.com/content/images/2024/04/24-04-lock-screen-closed.png)

Now it will download the packages, refresh/update packages, and install all the essentials.

![ubuntu 24.04 lts upgrade process screenshot](https://itsfoss.com/content/images/2024/04/24-04-upgrade-process.png)

Next, you will be shown a prompt to remove obsolete packages. You can choose to keep any of them, but for the most part, you should be good.

![Notification to Remove Obsolete packages](https://itsfoss.com/content/images/2024/04/24-04-obsolete.png)

You can continue the upgrade process and when it is done, it will ask you to restart the system to apply the upgrade.

And, done! **You have Ubuntu 23.10 installed on your system now:**

In case you are still using Ubuntu 22.04 LTS, and deciding if you want to upgrade to Ubuntu 24.04 LTS, you can decide by checking the changes between the two LTS editions:
