I have been running Ubuntu 24.04 LTS on a ThinkPad X1 Carbon since the week it shipped, and the only times I have had to think about the kernel have been the times I have had to debug something stupid. A flaky Bluetooth stack. An Nvidia driver that would not survive a sleep cycle. A fingerprint reader that stopped working after a point release. The Linux 7.0 HWE kernel that Canonical started pushing to 24.04 desktop users this week is, finally, a kernel I am going to actively want, and not one I have to chase down because something broke.
Here is the thing about LTS (Long Term Support) releases. The promise is that they are stable, supported, and boring. The cost is that they ship with a kernel that is already two years behind mainline (the constantly-updated development branch of the Linux kernel that Linus Torvalds shepherds) when they launch, and that gap is what makes your brand new laptop occasionally feel like a beta test. Hardware Enablement, the HWE stack that Ubuntu 24.04 desktop installs default to, exists to close that gap without forcing you to abandon the LTS promise. Most of you have it already. Most of you just do not know what it does.
What Lands With the 7.0 Jump
The kernel jump from 6.17 to 7.0 is one of those version bumps where the number matters less than the contents. If you have a recent laptop and have been fighting a driver that refuses to behave, this update is what you have been waiting for.
There is a quieter story behind it that explains why this update is happening the way it is. Ubuntu 25.10 reached end of life in July 2026, which means the only supported Ubuntu releases right now are the LTS lines: 22.04, 24.04, and 26.04. That is why your 24.04 install is suddenly getting a major kernel bump out of cycle. Canonical is consolidating the active support matrix, and HWE is how 24.04 keeps feeling like a current release until the in-place upgrade to 26.04 lands next year.
If you installed 24.04 as a server or as a minimal desktop and explicitly chose the GA (General Availability) kernel, you will not get this update. That path is for people who need maximum stability, and it is a reasonable one. Most desktop installs land on HWE by default, which is why most of you will see it sitting in your update manager today.
How To Pull It If Your Updater Is Sleeping
If the update has not surfaced in your graphical updater yet, two quick checks. From Software and Updates, make sure the source you are downloading from is the Main server. Regional mirrors can lag by hours during a major kernel rollout. If everything looks right and you do not want to wait, pull the package from the command line:
sudo apt update
sudo apt install linux-generic-hwe-24.04
Then reboot and run uname -r to confirm. The version string should end in 7.0.x. If the new kernel does not play well with something on your machine, hold Shift at boot to drop into the GRUB menu (the bootloader screen that lets you pick which kernel to start), choose Advanced options for Ubuntu, and boot the previous kernel. That is why LTS distributions are kind to live with: a bad kernel update is never an outage, just an extra reboot.
Where the 24.04.5 Release Fits
The 24.04.5 LTS point release ships on August 27, 2026, and it folds the 7.0 kernel and Mesa 26 graphics stack into the install ISO. If you are imaging new machines in the next month, that is the ISO you want. If you are already running 24.04.4 with HWE, you can skip the download and just take the regular update, because you are running the same stack the ISO will hand out.
The 24.04.5 release also brings news for anyone thinking about the next jump. Until that point release lands, moving from 24.04 LTS to 26.04 LTS requires a fresh install rather than an in-place upgrade. The official upgrade tool is expected to ship alongside 24.04.5 later this month. If 24.04 is running anything you cannot rebuild from scratch in an afternoon, wait for the upgrade path instead of cutting over early.
When NOT To Pull The Kernel
Most people should run the update on their normal schedule and never think about it again. There are a few situations where the right move is to wait a few weeks, or skip the HWE track entirely.
If you run a workstation with a paid Nvidia driver that you configured by hand and you are not in a position to debug a kernel mismatch on the day of the update, hold the update for two weeks and let the early adopters find the edge cases for you. If you maintain a production server on a strict change window, the kernel bump belongs in the next maintenance window, not today. If you are one of the small but real number of people who rely on out-of-tree kernel modules (kernel code that lives outside the main Linux source tree and has to be recompiled when the kernel changes), DKMS (the Dynamic Kernel Module Support system that automatically rebuilds third-party modules against new kernels) will catch the usual suspects but cannot catch everything, and the right day to discover that is a day you can troubleshoot.
Profiles that should hold the update at least a week:
- Workstations with hand-installed Nvidia proprietary drivers on production hardware
- Production servers on a Friday-afternoon-is-for-emergencies-only change policy
- Hosts that run custom kernel modules built outside DKMS or the standard repos
- Setups where a kernel mismatch would cascade into a colleague’s Friday afternoon
- Long-running containers pinned to a specific kernel ABI (Application Binary Interface, the contract a kernel exposes to user-space programs) that you cannot update on the fly
What I Would Tell Past Me
Three things I wish I had internalized about LTS kernel management years ago, that this update is a good reminder of:
- The kernel that ships with the install ISO is not the kernel you will be running in month six. Plan for that gap from day one.
- The HWE track is the default for a reason. If you ever think you need to switch to GA, you almost certainly do not.
- The previous kernel is always a menu option away. Stop treating kernel updates like production database migrations.
The Things Most People Will Notice
The visible behavior changes are not dramatic, which is the point. Your laptop will wake up from sleep without forgetting it has a Wi-Fi connection. Your external monitor will reconnect without you unplugging it twice. Your battery will last a little longer on a coffee-shop day because the power-management code has been rewritten in the bits that mattered. None of this is the kind of thing you would write home about, and all of it is the kind of thing that, once you get used to it, makes you dread going back.
If you take one thing from this article, run the update the next time you have fifteen uninterrupted minutes, reboot once, and forget about kernels until the next LTS point release in 2030 or so. The whole reason an HWE track exists is so that you do not have to think about kernels, and this update is what good HWE looks like.
Trade-offs
Pulling a major kernel forward means your third-party modules need to play along. Most users with Nvidia drivers, ZFS, or VirtualBox get automatic DKMS rebuilds and never notice. If you run something exotic, do this on a day you can troubleshoot, not before a deadline. The update is genuinely useful, but it is a normal forward step in the kernel series, and it will not turn a five-year-old laptop into a workstation. What it does is keep a supported install moving in the right direction without forcing a wipe and reinstall, and for most users that is exactly the right trade.
