Ubuntu 24.04.3, the third point release of the current Ubuntu LTS, is out! Ubuntu developer team announced the release on Thursday:
The Ubuntu team is pleased to announce the release of Ubuntu 24.04.3 LTS (Long-Term Support) for its Desktop, Server, and Cloud products, as well as other flavours of Ubuntu with long-term support.
As usual, this point release includes many updates and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-severity bugs, with a focus on.
First, the new released introduced Linux 6.14 HWE kernel backported from 25.04.
The new kernel features THC driver for touchscreen and touchpad functionality in modern Intel Laptops, faster performance playing Windows games in Linux (via Wine or Proton), Microsoft “Copilot” key, faster suspend and resume on Dell XPS-13-9300, and many new & updated hardware support! See THIS PAGE for more.
Besides that, it added Realtek 8852BE-VT (10ec:b520) network adapter support in OEM kernel, and following new hardware features support:
- Wifi 6GHz for Philippines on Qualcomm WCN6856.
- GPU driver on Qualcomm QCS6490 / SA8775.

It also added LED control for Lenovo ThinkPad with Realtek RT713 codec + RT1318 amplifier on Intel LNL platform, corrected ThinkPad X9-15 Gen1 Touchpad Functionality.
There are as well hardware compatibility fixes. They include low audio output volume via headphone on the Tarako DELTA platform, no sound output from one of the speaker on HP ZBook, and no audio output for the cs35l56 amplifier on HP LAPZ16 series laptops.
On computers come with AMD integrated GPU and NVIDIA dedicated GPU, if the iGPU is not VGA compatible and pci order is later than NVIDIA, system previously will incorrectly select NVIDIA as primary GPU. And, switch from AMD to NVIDIA could freeze the Wayland session. Now, both the issues are fixed.
Besides the updates for hardware support, it updated libvirt to correctly detect Intel CPU models, and allow to running KVM VMs with full boot order support on s390x (e.g, IBM Z, LinuxONE).
The ubuntu-drivers command line utility in the release has been updated with new --include-dkms option. So, ubuntu-drivers list (without that option) will no longer list DKMS only drivers that will break secure boot.
As you may know, apt now outputs warnings when using signature key with weak algorithm, and it promotes the weak key warnings to error in v2.8.4+.
Many old keys have been marked as un-trusted in the past few releases. Ubuntu 24.04.3 (with apt 2.8.3) revoked them in the past v2.8.0, 2.8.1, and 2.8.2, giving third party repository maintainers more time to update their keys. Though, user may choose to override the policy change to avoid the warnings/errors.
24.04.3 also fixed numerous issues for the Ubuntu desktop. It fixed desktop icon renaming issue, drag’n’drop issue between x11 and wayland applications, wi-fi connecting from GDM login screen, and various shell and nautilus crashes.
For Xorg session, it fixed OSK (on-screen keyboard) not working on touchscreen, shell elements don’t respond to touchscreen, and touchscreen disabled issue after resume from suspend.
The Orca screen reader has been updated to announce “checking for updates”, and say if a package selected or not in Update Manager (Software Updater). And, it now reads associated keybindings for actions and gnome-initial-setup windows properly.
Other changes include:
- Forcibly maps mic mute key and touchpad function keys to F20-F23
- Support Epoxy Cloud Archive for installing newer versions of OpenStack.
- Backport netplan.io 1.1.2-2 to 24.04.
- Fix that sshd cannot bind to IPv4 interfaces.
- IPv6 support for iBFT iSCSI boot.
- Fix kernel panic when unmounting ZFS snapshots.
