Linux 5.10 LTS Status and More Stables Releases of Linux Announced Today

  • Linux 5.10 LTS Will Only Be Maintained Until EOY 2022 Unless More Companies Step Up

    Announced a few years ago was the notion of "extended" LTS kernel versions whereby the long term support cycle would span six years rather than the usual two years for LTS kernels in providing maintenance and bug/security fixes to the codebase. This means Linux 5.4 LTS is supported until the end of 2025, Linux 4.19 until the end of 2024, and even Linux 4.14 until the start of 2024. But with the recently minted Linux 5.10 LTS at least for now it's only being committed to maintenance until the end of next year.

    There's been differing remarks/indications for how long the Linux 5.10 long-term support cycle would last with many expecting six years given that's what has been happening on recent LTS kernels -- even the Linux 4.4 kernel is being planned for maintenance until February 2022 and Linux 4.9 until 2023. Linux stable maintainer Greg Kroah-Hartman has now provided a more transparent answer on the Linux kernel mailing list stemming from the talk over how long Linux 5.10 will be maintained.

  • Three stable kernels

    Stable kernels 5.10.11, 5.4.93, and 4.19.171 have been released. They contain important fixes and users should upgrade.

The LTS Linux Kernel 5.10 To Be Maintained For Only 2 Years

  • The LTS Linux Kernel 5.10 To Be Maintained For Only 2 Years If Companies Don’t Help Support It

    Linux Kernel 5.10 was the last kernel release of 2020. It is a long term support release.

    There are no hard and fast rules for the lifespan of a kernel release. A normal kernel is maintained by the kernel maintainers for 3-4 months. An LTS release on the other hand gets around 2 years of support usually.

    But since there are too much on the stake, at times, LTS release get extended support as well. Take Linux kernel 5.4 for instance. It will be supported for 6 years primarily for Android devices.

Linux maintainer says long-term support for 5.10 will stay...

  • Linux maintainer says long-term support for 5.10 will stay at two years unless biz world steps up and actually uses it

    Linux kernel maintainer Greg Kroah-Hartman has responded to complaints that the current promise of two years for 5.10 is not enough, explaining that support is not automatic but requires commercial help.

    Version 5.10 of the kernel was released in December and designated a "long-term maintenance" release, which generally means six years of support with important bugfixes and security patches. Broadcom's Scott Branden spotted that the official release table only specifies two years of support for 5.10, which has a projected EOL (end of Life) of December 2022. He raised a query on the kernel mailing list.

    "The 5.10 LTS kernel being officially LTS supported for 2 years presents a problem," he said. "Why would anyone select a 5.10 kernel with 2 year LTS when 5.4 kernel has a 6 year LTS... a 2 year declaration is not LTS any more."

    Maintainer Kroah-Hartman was quick to explain. First, he refuted the idea that two years is not LTS. "A 'normal' stable kernel is dropped after the next release happens, making their lifespan about 4 months long. 2 years is much longer than 4 months, so it still is a "long term supported" kernel," he said.

Helping Out With LTS Kernel Releases

  • Helping Out With LTS Kernel Releases

    A recent email thread about “Why isn’t the 5.10 stable kernel listed as supported for 6 years yet!” on the linux-kernel mailing list ended up generating a bunch of direct emails to me asking what could different companies and individuals due to help out. What exactly was I looking for here?

    Instead of having to respond to private emails with the same information over and over, I figured it was better to just put it here so that everyone can see what exactly I am expecting with regards to support in order to be able to maintain a kernel for longer than 2 years...

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
