In the following weeks, the users of Ubuntu 23.10 will receive an offer to upgrade to 24.04 automatically, and the users of 22.04 LTS will get the same offer in mid-August this year.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-year-2038-problem\"><span class=\"ez-toc-section\" id=\"The_year_2038_problem\"><\/span>The year 2038 problem<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>To start with, Ubuntu 24.04 fixed the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Year_2038_problem\" target=\"_blank\" rel=\"noreferrer noopener\">Y2K38 superbug<\/a> caused by storing the UNIX time as a 32-bit integer. This would have caused an integer overflow at 03:14:07 UTC on 19 January 2038, making our computers quickly travel to the 13th of December 1901. I lived through the Y2K problem, and I\u2019m happy that Ubuntu has led the initiative in solving such \u201ctime\u201d issues on time, thus killing any possibilities for paranoia and scaremongering as it was back in the 2000s. Ubuntu took up the challenge and updated thousands of packages to use 64-bit integers, thus making this an issue for future programmers in the year 292277026596 or the <a href=\"https:\/\/ximalas.info\/2015\/03\/10\/when-does-the-64-bit-unix-time_t-really-end\/\" target=\"_blank\" rel=\"noreferrer noopener\">Y2B96 bug<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1054\" height=\"381\" src=\"https:\/\/black.host\/blog\/wp-content\/uploads\/sites\/4\/2024\/04\/y2k_and_2038_2x.png\" alt=\"Y2K and Y2K38 rproblems\" class=\"wp-image-1720\" srcset=\"https:\/\/black.host\/blog\/wp-content\/uploads\/sites\/4\/2024\/04\/y2k_and_2038_2x.png 1054w, https:\/\/black.host\/blog\/wp-content\/uploads\/sites\/4\/2024\/04\/y2k_and_2038_2x-300x108.png 300w, https:\/\/black.host\/blog\/wp-content\/uploads\/sites\/4\/2024\/04\/y2k_and_2038_2x-768x278.png 768w\" sizes=\"auto, (max-width: 1054px) 100vw, 1054px\" \/><figcaption class=\"wp-element-caption\">Source: explainxkcd<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-kernel-and-networking-upgrades\"><span class=\"ez-toc-section\" id=\"Kernel_and_networking_upgrades\"><\/span>Kernel and networking upgrades<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The next big thing is, as always, a new kernel.<br>Ubuntu 24.04 comes with kernel version 6.8 which brings tons of new features, like: EEVDF scheduler, BcacheFS, 4096 CPU KVM, and tons of other things, which are a reason for an article on its own, so if you feel that you\u2019re up to reading feel free to check this <a href=\"https:\/\/discourse.ubuntu.com\/t\/introducing-kernel-6-8-for-the-24-04-noble-numbat-release\/41958\">post<\/a>.<\/p>\n\n\n\n<p>Ubuntu 24.04 upgraded to Netplan 1.0, a declarative network management tool that just officially debuted after seven years of active development under <a href=\"https:\/\/ubuntu.com\/blog\/introducing-netplan-v1\" target=\"_blank\" rel=\"noreferrer noopener\">Netplan v1.0<\/a>. Just as is the case with any other tool that is introducing software-defined kick in its field of work, we believe that netplan has already revolutionized network management on Linux devices, and with its support for InfiniBand devices, we can confidently say that Ubuntu made the right choice. And while we\u2019re at it, feel free to check out our latest guide on how to make <a href=\"https:\/\/black.host\/hc\/ipv6\/setting-up-ipv6-on-ubuntu-24-04-with-netplan\/\" target=\"_blank\" rel=\"noreferrer noopener\">static IPv6 configuration using Netplan on Ubuntu 24.04<\/a>, configuring IPv6 has never been easier, right? <\/p>\n\n\n\n<p>On the other hand, this release uses systemd v255.4 as the init system manager, it brings us updates in various toolchains like GCC, Python ( v3.12 is the default now ), Rust, Golang, .Net, etc., thus making Ubuntu a more desirable development platform as well.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-security-and-performance-first\"><span class=\"ez-toc-section\" id=\"Security_and_Performance_first\"><\/span>Security and Performance first<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>How Canonical tackled the whole XZ issue, and the changes they are introducing in each next release make a clear statement about their goals, making Ubuntu highly performant and one of the most secure Linux distributions. Ubuntu 24.04 is proof of this as it is packed with a lot of performance and security improvements, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Introducing performance toolkits for Ubuntu, thus raising the bar on performance management.<\/li>\n\n\n\n<li>irqbalance is no longer installed by default, as nowadays, the kernels are more than capable of handling high CPU workloads<\/li>\n\n\n\n<li>Apparmor now has support for unprivileged user namespace restrictions<\/li>\n\n\n\n<li>TLS 1.0, 1.1, and DTLS 1.0 are disabled by default<\/li>\n\n\n\n<li>APT disables 1024-bit RSA APT repository signing keys<\/li>\n\n\n\n<li>PPTP is <a href=\"https:\/\/bugs.launchpad.net\/ubuntu\/+source\/linux\/+bug\/2041751\" target=\"_blank\" rel=\"noreferrer noopener\">removed<\/a> as it is considered unsafe<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-improved-web-hosting-and-cloud-stacks\"><span class=\"ez-toc-section\" id=\"Improved_web_hosting_and_cloud_stacks\"><\/span>Improved web hosting and cloud stacks<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Just like the development toolkit, the server-side components received their fair share of upgrades:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Apache2&#8217;s default version is v2.4.58. Check this Apache Lounge <a href=\"https:\/\/www.apachelounge.com\/changelog-2.4.html\" target=\"_blank\" rel=\"noreferrer noopener\">changelog<\/a> to see the most recent updates in Apache2.<\/li>\n\n\n\n<li>Nginx comes in version 1.24, which is a major jump from the previous release.<\/li>\n\n\n\n<li>PHP has been to 8.3.6, which is the current latest PHP version, we highly recommend this <a href=\"https:\/\/php.watch\/versions\" target=\"_blank\" rel=\"noreferrer noopener\">php.watch<\/a> to keep up to date with the latest changes in the PHP world, as the PHP Foundation has ramped up the development in the past year.<\/li>\n\n\n\n<li>Ubuntu 24.04 puts focus on containers and virtualization, as we can see from the updates and the support of the latest virtualization and container tools like: Containerd 1.7.12, Docker 24.0.7, libvirt v10.0.0, LXD 5.21.0 LTS, QEMU v8.2.1<\/li>\n<\/ul>\n\n\n\n<p>For the sake of this article, we are showcasing just a tiny part of the critical components that make up the web. You can checkout the official <a href=\"https:\/\/discourse.ubuntu.com\/t\/noble-numbat-release-notes\/39890\" target=\"_blank\" rel=\"noreferrer noopener\">Noble Numbat release notes<\/a> if you want to get more details about all the new updates it introduces. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-so-is-it-worth-it\"><span class=\"ez-toc-section\" id=\"So_is_it_worth_it\"><\/span>So, is it worth it?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In addition to the things pointed out above, Ubuntu 24.04 comes packed with support for cloud environments, extended support for virtualization tools mentioned above, clustered filesystems like GlusterFS and Ceph, and high availability clustering tools such as Open Stack and open vSwitch.<\/p>\n\n\n\n<p>All of this combined with Canonical streamlining effort, makes this Ubuntu release one of the best Ubuntu releases ever, thus worthy of the title noble update.<\/p>\n\n\n\n<p>Our final verdict is to definitely upgrade to this release. The rule of thumb is to follow Ubuntu&#8217;s official guidelines and wait for the proper timing if you plan to perform a system upgrade. But if this article hyped you so much that you can&#8217;t wait anymore, you can always migrate to a brand-new install.<\/p>\n\n\n\n<p>As of today, Ubuntu 24.04 is available for all of our <a href=\"https:\/\/black.host\/unmetered-vps-hosting\">unmetered VPS hosting<\/a> plans. If you\u2019re a customer interested in migration, write to us, and we will provide you with a free instance where you can migrate your data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Finally, the long-awaited version of Ubuntu is here after some initial delay due to major security issues related to the XZ compression library, which had a hidden backdoor since February 26th, allowing the attacker to gain SSH access.
