Ubuntu 20.04: Welcome to the future, Linux LTS disciples

Filed under
Ubuntu

Ubuntu 20.04 ships with 5.4 kernel, which brings support for Intel's Comet Lake chips as well as the beginning of Tiger Lake support. If you keep track of the kernels, you might be disappointed, since the baked-in support for Wireguard in the kernel doesn't come until 5.6. But fear not VPN users: Ubuntu has backported the Wireguard bits so that you can enjoy using Wireguard with your VPN provider today (assuming your VPN supports it).

More exciting, quite frankly, is the continued work on integrating ZFS into Ubuntu. There's nothing new about the usefulness of ZFS, but usefulness is not necessarily the same as usability. Ubuntu's developers have put a lot of work into making ZFS easier to use, both in terms of making backups via snapshots and the arguably more important part of easily restoring your system using those snapshots.

New ZFS features in this release include zfs 0.8, which supports hardware accelerated encryption and some performance gains among other things. But the more interesting addition is Ubuntu's Zsys utility, which essentially makes it easier to see what's happening under the hood.

This is still highly experimental, and it's hidden away during the install process, but if you click the advanced features section of the disk partitioning tool during installation you'll see an option "EXPERIMENTAL: erase disk and use ZFS." It's no longer in scary bold red text the way it was in 19.10, which I take to mean that things are improving. Do note, however, this message still appears in all caps. This option is definitely not what you want to use on a production system looking for LTS-style stability.

  • Ubuntu 20.04 Is The Future Of Computers

    Ubuntu 20.04 (Focal Fossa, as this launch, is understood) is a Lengthy Time period Assist (LTS) launch, which implies Ubuntu’s guardian firm, Canonical, will present assist by means of 2025. The LTS releases are what Canonical calls “enterprise-grade,” and these are usually conservative on the subject of adopting new technologies. The interim releases, like last year’s Ubuntu 19.10, are as a substitute the place the corporate tends to experiment.

This is to say, and it is a massive replacement that the majority of Ubuntu’s person base will likely be upgrading to ultimately.

This replaces been very strong in day-to-day use, and it nonetheless manages to (optionally!) embrace assist for some cutting-edge new options, just like the beginnings of software to handle ZFS snapshots. There’s additionally a significant kernel bump, and appreciable work has gone into enhancing and sharpening the default Yaru theme.

  • 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.
