又一次，一如既往的一年一度，我们迎来全新的 Ubuntu 发布！


这次发布的版本是 **Ubuntu 23.10** ，这不是一个 [长期支持](https://itsfoss.com/long-term-support-lts/)（LTS）版本，它的代号是 “Mantic Minotaur” （预言牛头人）。


非 LTS 版本更偏向于满足那些想要获取到 Ubuntu 最新以及最出众特性的用户。


对于那些希望长时间坚守一个版本的用户，我们建议使用 LTS 版本，比如 [Ubuntu 20.04](https://itsfoss.com/things-to-do-after-installing-ubuntu-20-04/) 和 [Ubuntu 22.04](https://itsfoss.com/ubuntu-22-04-release-features/)。


总之，让我们深入了解这次发布的新版本，去发现其中的亮点。



> 
> ? Ubuntu 23.10 将会 **提供九个月的支持**，一直到 2024 年 7 月为止。

### ⭐ Ubuntu 23.10：新版调整了什么？


![](/data/attachment/album/202310/13/095826lstclmrxdcpd0e1d.png)


即使这是一个非 LTS 发布，但是 **Ubuntu 23.10 却包含了许多有趣的新特性和升级**。


一些主要亮点包括：


* 更新升级的安装程序
* 受限的非特权用户命名空间
* GNOME 45
* 全新的壁纸
* 基于 Flutter 的应用商店
* Linux 内核 6.5


### 更新升级的安装程序


![](/data/attachment/album/202310/13/095826cz2qv2ovo8vv8p60.png)


首先，Ubuntu 23.10 的安装程序 **开始实验性地支持两大重要功能** ：


其一是 [TPM 支持的全盘加密（FDE）](/article-16187-1.html)，这意味着采用全新的加密机制。它将与你主板上的 TPM 芯片协同运作。


其二是期待已久的 [ZFS 支持](https://news.itsfoss.com/ubuntu-23-10-zfs/) 再次回归到安装程序中，它在 [Ubuntu 23.04](https://news.itsfoss.com/ubuntu-23-04-release/) 被移除。

### 受限的非特权用户命名空间


![](/data/attachment/album/202310/13/095827dygg312bg44go4qg.png)


Ubuntu 23.10 首次推出一项新的安全功能。它限制了内核的 “非特权用户命名空间” 特性，这有助于应用程序创建更安全的沙箱环境。


这个特性很有用，那为什么要限制它呢? 原因在于，这个内核特性可能被攻击者利用。


为了消除与这个特性相关的风险，[AppArmor](https://ubuntu.com/server/docs/security-apparmor) 将被用于有选择地允许/禁止非特权用户命名空间。


这个安全特性默认是关闭的，但可以通过命令行选择开启。Canonical 将搜集用户反馈，然后可能决定通过更新将其设为默认。 


### GNOME 45


![](/data/attachment/album/202310/13/095827yv2mdq6i00vizc52.png)


Ubuntu 23.10 提供了最新发布的 [GNOME 45](/article-16215-1.html) 桌面环境，它包括了 **优化过的系统设置应用**、**更新的核心应用**，并 **新增了两个应用**，名为 <ruby> <a href="/article-15887-1.html">  放大镜 </a> <rt>  Loupe </rt></ruby> 和 <ruby> <a href="/article-15789-1.html">  快照 </a> <rt>  Snapshot </rt></ruby>。


新的 [药丸形工作空间指示器](https://news.itsfoss.com/gnome-activities-indicator/) 也在这次发布中首次亮相，虽然不是每个人都会喜欢。 


### 新的壁纸


![](/data/attachment/album/202310/13/095828ajrnbo8v8dx7bnpv.png)


Ubuntu 23.10 版本发布，也不忘继续传统，**推出了全新的壁纸** ，这些壁纸主题都与其代号保持一致。所有壁纸看起来都非常不错，这些都是从几个月前举行的 Mantic Minotaur [壁纸比赛](https://discourse.ubuntu.com/t/mantic-minotaur-23-10-wallpaper-competition/37235) 中被选中的。


你可以通过 [官方博客](https://ubuntu.com/blog/into-the-labyrinth) 查找更多有关这些极酷壁纸的信息。

### 基于 Flutter 的应用商店


![](/data/attachment/album/202310/13/095828mexx3y85eeeo76e6.png)


得益于在 Ubuntu 23.10 上推出了 **全新的 [基于 Flutter 的商店](https://news.itsfoss.com/ubuntu-23-10-ubuntu-store/)** ，Canonical 推将 Ubuntu 各种元素 Flutter 化的努力见到了效果。这个新商店拥有 **更新的布局**、**全新的应用视图** ，以及 **更好的搜索功能**。


你在其中可以找到 Snap 和 Deb 包。


### Linux 内核 6.5


![](/data/attachment/album/202310/13/095829nm8j78sdoglzmts1.png)


首先，让我们来了解下让一切变为可能的原动力。Ubuntu 23.10 版本采用了相对更新的 [Linux 内核 6.5](https://news.itsfoss.com/linux-kernel-6-5-release/)。


这一特性让 Ubuntu 能够使用到一些新的硬件支持，如 **Wi-Fi 7**、**USB4**、**针对 AMD FreeSync 视频的即插即用支持**，以及**对 AMD Radeon RX 7000 系列显卡的超频支持** 等。


### ?️ 其他变动


除了之前提到的特性，还有一些其他值得注意的变动：


* 支持最新发布的 [树莓派 5](https://news.itsfoss.com/raspberry-pi-5/) 和 [HiFive Pro P550](https://www.sifive.com/boards/hifive-pro-p550)。
* [为 PPA 提供增强的安全性](https://news.itsfoss.com/ubuntu-23-10-ppa/)。
* 对 Rust 的支持进一步增强。
* 加入了 [Shotwell 0.32](https://gitlab.gnome.org/GNOME/shotwell/-/blob/master/NEWS)。
* 推出了全新升级的平铺辅助工具。

It is that time of the year again, when we get to see a new Ubuntu release!

This time it's **Ubuntu 23.10**, which is not a [Long-Term support](https://itsfoss.com/long-term-support-lts/?ref=news.itsfoss.com) (LTS) version, and is code-named as '**Mantic Minotaur**'.

Such releases are geared more towards users who want the latest and greatest that Ubuntu has to offer.

For users who want to stick with one version for a long time, we suggest LTS releases such as [Ubuntu 20.04](https://itsfoss.com/things-to-do-after-installing-ubuntu-20-04/?ref=news.itsfoss.com) and [Ubuntu 22.04](https://itsfoss.com/ubuntu-22-04-release-features/?ref=news.itsfoss.com).

Anyway, let's dig into this release and check out its highlights.

**supported for nine months**until July 2024.

## ⭐ Ubuntu 23.10: What's New?

![a screenshot of the ubuntu 23.10 desktop](https://news.itsfoss.com/content/images/2023/10/Ubuntu_23.10_1-1.png)

Even though this is a non-LTS release,** Ubuntu 23.10 packs in loads of interesting features and improvements**.

Some key highlights include:

**Installer Upgrades****Restricted unprivileged user namespaces****GNOME 45****New Wallpapers****Flutter-based App Store****Linux Kernel 6.5**

### Installer Upgrades

![a screenshot of the experimental zfs and tpm-packed fde support](https://news.itsfoss.com/content/images/2023/10/Ubuntu_23.10_2.png)

For starters, the installer for Ubuntu 23.10 features **experimental support for two major features**:

One is the ** TPM-backed full-disk encryption **(FDE)

**,**that sees a completely revamped mechanism being implemented for encrypting disks. It works in tandem with the TPM chip on your motherboard.

The other is the long-awaited return of [ ZFS support](https://news.itsfoss.com/ubuntu-23-10-zfs/) to the installer, after it was dropped in the

[Ubuntu 23.04](https://news.itsfoss.com/ubuntu-23-04-release/)release.

### Restricted unprivileged user namespaces

![ubuntu apparmor](https://news.itsfoss.com/content/images/2023/10/apparmor-ubuntu-23-10.png)

Ubuntu 23.10 debuts a new security feature. It restricts the kernel feature '*unprivileged user namespaces*', which is useful to let applications create a more secure sandbox.

If it is useful, why restrict it? Well, the kernel feature lets attackers exploit a system.

So, to eliminate the risk associated with the feature, [AppArmor](https://ubuntu.com/server/docs/security-apparmor?ref=news.itsfoss.com) will be used to selectively allow/disallow unprivileged user namespaces.

This security feature will not be enabled by default but as an opt-in via command line. Canonical will collect user feedback and then may decide to push it as the default with an update.

### GNOME 45

![a screenshot of software information on ubuntu 23.10](https://news.itsfoss.com/content/images/2023/10/Ubuntu_23.10_3.png)

Ubuntu 23.10 features the recently released [ GNOME 45](https://news.itsfoss.com/gnome-45-release/) desktop environment that features a

**tweaked system settings app**,

**updated core apps**with the

**inclusion of two new apps**called '

**' and '**

[Loupe](https://news.itsfoss.com/loupe-image-viewer/)**'.**

[Snapshot](https://news.itsfoss.com/gnome-snapshot/)Even the new [ pill-shaped workspace indicator](https://news.itsfoss.com/gnome-activities-indicator/) has made a debut with this release, though not everyone might be on board with that.

### New Wallpapers

![a screenshot of the new wallpapers on ubuntu 23.10](https://news.itsfoss.com/content/images/2023/10/Ubuntu_23.10_4.png)

As is tradition, the Ubuntu 23.10 release also **features new wallpapers** themed according to its code-name. All of them look quite nice, and these were selected from the Mantic Minotaur [wallpaper competition](https://discourse.ubuntu.com/t/mantic-minotaur-23-10-wallpaper-competition/37235?ref=news.itsfoss.com) that was held a few months prior.

You can check the [official blog](https://ubuntu.com/blog/into-the-labyrinth?ref=news.itsfoss.com) to know more about these extremely cool wallpapers.

### Flutter-based App Store

![a screenshot of the new fultter based app store on ubuntu 23.10](https://news.itsfoss.com/content/images/2023/10/Ubuntu_23.10_5.png)

Canonical's push for Flutter-basing the various elements of Ubuntu has received a boost thanks to the implementation of **a new Flutter-based store on Ubuntu 23.10**. It features

**an updated layout**,

**a new application view**, and

**better search functionality**.

You can find both Snap and Deb packages with it.

### Linux Kernel 6.5

![a screenshot of the neofetch output on ubuntu 23.10](https://news.itsfoss.com/content/images/2023/10/Ubuntu_23.10_6.png)

And finally, we have the magic sauce that makes it all happen. **Ubuntu 23.10 features the relatively new Linux kernel 6.5**.

This allows Ubuntu to take advantage of the newer support such as **Wi-Fi 7**, **USB4**, **out-of-the-box support for AMD FreeSync video**, **overclocking support for AMD Radeon RX 7000 series graphics cards** and more.

### 🛠️ Other Changes

Other than the highlights, here are some other changes worth noting:

**Support for the recently released**[Raspberry Pi 5](https://news.itsfoss.com/raspberry-pi-5/), and[HiFive Pro P550](https://www.sifive.com/boards/hifive-pro-p550?ref=news.itsfoss.com).[Enhanced security](https://news.itsfoss.com/ubuntu-23-10-ppa/)for PPAs**Better support for Rust.****Inclusion of**[Shotwell 0.32](https://gitlab.gnome.org/GNOME/shotwell/-/blob/master/NEWS?ref=news.itsfoss.com).**Introduction of a vastly improved tiling assistant.**
