作为 Ubuntu 20.04 LTS 的第五个维护版本,Ubuntu 20.04.5 LTS 现已可下载。这个版本集合了自 2 月发布的 Ubuntu 20.04.4 LTS 以来的所有安全补丁、错误修复和应用程序更新,但是没有新功能。

没有新功能就意味着,如果你正在运行的就是 Ubuntu 20.04 LTS ,且在 Ubuntu 20.04.5 发布之前就已经安装了所有可用的更新,则无需重新安装 20.04.5 LTS。此版本适用于从其他 LTS 版本升级过来的用户。

Ubuntu 20.04 LTS 采用的是 Linux 5.15 内核,与新 ISO 捆绑在一起的其他软件更新包括 GNOME Shell 3.36.8、LibreOffice 6.4.7.2 和 Mozilla Firefox 104,但不是 Snap 版本。

Ubuntu 22.10 将由 Linux 5.19 内核驱动。尽管到目前为止,Ubuntu 22.10 的开发仍然在 Linux 5.15 LTS 内核上运行。但最新推出的 Kinetic 存档显示,Ubuntu 22.10 正在从 Linux 5.15 切换到 Linux 5.19,作为这个非 LTS Ubuntu 版本的预期内核。

Linux 5.19 于 7 月底发布,Linux 6.0 稳定版要到 10 月初才会发布。但 Ubuntu 22.10 的内核冻结日期是 10 月 6 日,稳定版本发布日期在 10 月 20 日。Canonical 一向趋于保守,不会冒跳票延期的风险选择最新的 Linux 6.0 内核。

目前,Linux 5.19 内核构建已被定位在 kinetic-proposed 中,很快就会向 Ubuntu 22.10 的开发用户提供,以取代现有的基于 5.15 的内核。此外,Ubuntu 22.10 将随桌面版 GNOME 43、Mesa 22.2 图形驱动程序、作为默认系统编译器的 GCC 12 以及各种其他更新包一起提供。

As the fifth maintenance release of Ubuntu 20.04 LTS, Ubuntu 20.04.5 LTS is now available for download. This release brings together all the security patches, bug fixes and application updates since the February release of Ubuntu 20.04.4 LTS, but no new features.

No new features means that if you’re running Ubuntu 20.04 LTS and have installed all available updates before Ubuntu 20.04.5 was released, you don’t need to reinstall 20.04.5 LTS. This release is for users upgrading from other LTS releases.

Ubuntu 20.04 LTS uses the Linux 5.15 kernel, and other software updates bundled with the new ISO include GNOME Shell 3.36.8, LibreOffice 6.4.7.2, and Mozilla Firefox 104, but not the Snap version.

Ubuntu 20.04.5 LTS can be downloaded from the Ubuntu website. It’s available as a 3.1GB ISO. https://releases.ubuntu.com/focal/

 

Ubuntu 22.10 will be powered by the Linux 5.19 kernel. Although so far, Ubuntu 22.10 development is still running on the Linux 5.15 LTS kernel. But the latest Kinetic archive shows that Ubuntu 22.10 is switching from Linux 5.15 to Linux 5.19 as the expected kernel for this non-LTS Ubuntu release.

Linux 5.19 was released at the end of July, and the stable version of Linux 6.0 will not be released until early October. But Ubuntu 22.10’s kernel freeze date is October 6, and the stable release date is October 20. Canonical has always tended to be conservative and will not risk delaying the ticket to choose the latest Linux 6.0 kernel.

Currently, the Linux 5.19 kernel build has been positioned in kinetic-proposed and will soon be available to Ubuntu 22.10 development users to replace the existing 5.15-based kernel. Additionally, Ubuntu 22.10 will ship with GNOME 43 for desktop, Mesa 22.2 graphics drivers, GCC 12 as the default system compiler, and various other updates.
