Ubuntu 21.10 是下一个大型 LTS 更新之前的最后一个非 LTS 版本。代号为 Impish Indri 的 Ubuntu 21.10 将被支持**九个月，直到 2022 年 7 月**。


除非你想尝试最新和最棒的功能，否则你应该坚持使用 Ubuntu 20.04 LTS 并等待 Ubuntu 22.04 LTS。


现在你可以下载 Ubuntu 21.10 并在你的系统上安装，让我重点介绍一下这次更新的几个亮点。


### Ubuntu 21.10 “Impish Indri” 有何新变化？


![](/data/attachment/album/202110/16/100218wuad5r5huicfu5uf.png)


Ubuntu 21.10 出炉时有几个重大变化。一些最有影响的改进包括：


* 新的安装程序
* 增加了 GNOME 40
* 抛弃了混合主题，选择了浅色/深色主题
* 包括 Linux 内核 5.13
* 加入了支持蓝牙 LDAC 的 PulseAudio 15
* 带有 Nvidia 专有驱动程序的 Wayland 会话


GNOME 40 可以说是 Ubuntu 中令人耳目一新的变化，但你只有在体验之后才能知道。为了让你快速感受一下，下面是这个版本中你可以期待的所有变化。


#### 粉饰一新的安装程序

虽然 Ubuntu 的安装程序很容易使用，对新手也很友好，但 Canonical 希望通过对安装程序进行视觉和技术上的改造，使其更上一层楼。


开发团队利用 Flutter 使安装程序在所有其他 Ubuntu 口味和系统配置中保持一致。

#### GNOME 40


![](/data/attachment/album/202110/16/100221lltmnarskoo2ar56.png)


Ubuntu 的桌面体验与 GNOME 40 融为一体，没有提供任何混乱的布局。停靠区依然存在，水平活动概览也与之无缝衔接。


当然，[GNOME 40](https://news.itsfoss.com/gnome-40-release/) 中的所有改进，如核心应用程序的更新、工作区的改变等等，都会延续到 Ubuntu 21.10 中，只是 Canonical 做了一些改动。


就我个人而言，我并不喜欢 GNOME 40 的工作流程，但你可能会想体验一下。


#### 主题的变化


![](/data/attachment/album/202110/16/100222blcc9nb0nlg955vc.png)


我喜欢改进后的颜色方案，其目的是为了更好地与 Canonical 的 Ubuntu 品牌相融合。


然而，当涉及到与应用程序和整体主题选择的一致性时，混合（标准）主题是有点问题的。


在 Ubuntu 21.10 中，你会看到深色和浅色主题，而浅色是开箱即用的默认选择。如果你想进一步了解，你可以阅读我们的 [过去的报道以更多了解这一变化](https://news.itsfoss.com/ubuntu-21-10-theme-change/)。


#### Linux 内核 5.13


Linux 内核 5.13 的加入增加了对未来的英特尔和 AMD 芯片的支持，以及对苹果 M1 的初步支持。


你可以就一步了解 [Linux 内核 5.13](https://news.itsfoss.com/linux-kernel-5-13-release/) 的信息，但总的来说，它应该给你更好的硬件兼容性。


#### PulseAudio 15 支持蓝牙 LDAC


考虑到现在有更多的蓝牙耳机支持 LDAC，当你在桌面上使用 Ubuntu 21.10 时，你可以利用这一功能。


别担心，如果你不想尝试非 LTS 版本，Ubuntu 22.04 LTS 将包括同样的改进。所以，你必须耐心等待，直到明年才能利用这一点。


除此之外，PulseAudio 15 还带来了一系列的改进，你可以参考它的 [官方更新日志以了解更多信息](https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/15.0/) 。


#### Wayland 会话与 NVIDIA 专有驱动程序


现在，即使你使用 NVIDIA 专有的驱动程序，如果你需要也可以切换到 Wayland 会话。


#### Ubuntu 21.10 中的其他变化


![](/data/attachment/album/202110/16/100223ezikyfolzl9km75m.png)


Ubuntu 21.10 版本为其云镜像、树莓派支持和安全性带来了一系列高质量的变化。


其中一些值得注意的变化包括：


* [Firefox 默认采用 Snap](https://news.itsfoss.com/ubuntu-firefox-snap-default/)
* LibreOffice、Thunderbird 更新
* Ubuntu Sever 的改进
* 新的 PHP 默认为 8.0.8

Ubuntu 21.10 is the last non-LTS release before the next big LTS update. Codenamed, Impish Indri, Ubuntu 21.10 will be supported for **nine months until July 2022**.

Unless you want to try the latest and greatest features, you should stick to Ubuntu 20.04 LTS and wait for Ubuntu 22.04 LTS.

Now that you can download and install Ubuntu 21.10 on your systems, let me highlight a few things about this update.

## Ubuntu 21.10 “Impish Indri”: What’s New?

![](https://news.itsfoss.com/content/images/wordpress/2021/10/ubuntu-21-10-full-1024x507.png)

Ubuntu 21.10 comes baked with several significant changes. Some of the most impactful improvements include:

- New installer
- Addition of GNOME 40
- Ditching the mixed theme and opting for light/dark theming
- Including Linux Kernel 5.13
- Inclusion of PulseAudio 15 with Bluetooth LDAC support
- Wayland session with Nvidia proprietary driver

GNOME 40 can be a refreshing change with Ubuntu but you can only tell that after you experience it. To give you a quick idea, here’s what you can expect with all the changes included in this release.

## Refreshed Installer

![](https://news.itsfoss.com/content/images/wordpress/2021/02/new-ubuntu-installer.png)

While Ubuntu’s installer was easy to use and newbie-friendly, Canonical wants to take it up a notch by giving the installer a visual and technical overhaul.

The dev team utilizes Flutter to make the installer consistent across all other Ubuntu flavors and system configurations.

## GNOME 40

![](https://news.itsfoss.com/content/images/wordpress/2021/10/ubuntu-21-10-new-gnome-40.png)

Ubuntu’s desktop experience blends in with GNOME 40 without offering any confusing layouts. The dock remains and the horizontal activity overview works seamlessly with that.

Of course, all the improvements in [GNOME 40](https://news.itsfoss.com/gnome-40-release/) like core app updates, workspace changes, and more carry over to Ubuntu 21.10 with a few teaks from Canonical.

Personally, I didn’t like the workflow with GNOME 40, but you may want to take it up for a spin.

## Changes in Theme

![](https://news.itsfoss.com/content/images/wordpress/2021/10/ubuntu-21-10-appearance-1024x719.png)

I like the improved color scheme that aims to blend in better with Canonical’s branding for Ubuntu.

However, the mixed (Standard) theme was a bit problematic when it came to being consistent with applications and overall theme selection.

Going forward with Ubuntu 21.10, you will only notice a dark and light theme while the light being the default choice out-of-the-box. If you’re curious, you can read our [past coverage to know more about this change](https://news.itsfoss.com/ubuntu-21-10-theme-change/).

## Linux Kernel 5.13

The addition of Linux Kernel 5.13 adds support for future Intel and AMD chips along with initial Apple M1 support.

You can explore more about [Linux Kernel 5.13](https://news.itsfoss.com/linux-kernel-5-13-release/) but overall, it should give you way better hardware compatibility.

## PulseAudio 15 With Bluetooth LDAC Support

Considering that more Bluetooth headphones now support LDAC, you get to utilize the capability when using Ubuntu 21.10 on your desktop.

Fret not, if you do not want to try a non-LTS release, Ubuntu 22.04 LTS will include the same improvement. So, you will have to be patient till next year to make use of that.

In addition to that, PulseAudio 15 brings in a range of improvements, you can refer to its [official changelog to know more about that.](https://www.freedesktop.org/wiki/Software/PulseAudio/Notes/15.0/?ref=news.itsfoss.com)

## Wayland Session with NVIDIA Proprietary Driver

Now, even if you use the proprietary NVIDIA drivers, you will be able to switch to a Wayland session if you need it.

## Other Changes in Ubuntu 21.10

![](https://news.itsfoss.com/content/images/wordpress/2021/10/ubuntu-21-10-about.png)

Ubuntu 21.10 release brings in a host of quality changes to its cloud images, Raspberry Pi support, and security as well.

Some of those notable changes include:

[Including Firefox as a Snap by default](https://news.itsfoss.com/ubuntu-firefox-snap-default/)- Package updates to LibreOffice, Thunderbird
- Ubuntu server improvements
- New PHP default to 8.0.8

If you want to explore all the technical details, you might want to refer to the [official release notes](https://discourse.ubuntu.com/t/impish-indri-release-notes/21951?ref=news.itsfoss.com).

## Download and Upgrade to Ubuntu 21.10

You can opt for a fresh installation or [upgrade from Ubuntu ](https://itsfoss.com/upgrade-ubuntu-to-newer-version/?ref=news.itsfoss.com)21.04 to Ubuntu 21.10 using the software updater.

Do note that if you are using Ubuntu 20.04 LTS, it is recommended to wait for the next LTS release, unless you know what you are doing.
