Ubuntu Studio 24.04 LTS Release Notes

Ubuntu Studio shares some of the same desktop features as Kubuntu. Please see Kubuntu release notes for additional information.

Getting Ubuntu Studio 24.04 LTS

Download a Disk Image

Bootable images for standard PCs/laptops

Instructions for burning the image to a USB flash drive can be found on the Burning ISO Howto. NOTE: This ISO image exceeds 4.0GB and might not write correctly to a DVD. We recommend USB flash drives be used as installation media 8GB or greater.

Check SHA256SUM for the downloaded ISO

It is recommended to check your image file so your installation goes smoothly. Compare your SHA256 checksum with the correct ones found alongside the images.

Upgrading to Ubuntu Studio 24.04 LTS

Upgrades to 24.04 LTS from 22.04 LTS are now supported. You should receive a notification if you are running Ubuntu Studio 22.04 that an upgrade is available. If you do not receive a notification about a month after the release of Ubuntu Studio 24.04.1, make sure you have plasma-distro-release-notifier installed.

To upgrade automatically, click on the notification icon in your system tray.

To manually upgrade, ensure the package press Alt+Space to invoke Krunner, and type the following:

do-release-upgrade -m desktop -f DistUpgradeViewKDE

Alternatively, you can do this from the Konsole terminal:

do-release-upgrade -m desktop

Changes for this release
(compared to 23.10 Mantic Minotaur)

This release includes further improvements to Ubuntu Studio Installer which now also includes the Ubuntu Studio Audio Configuration utility to improve configuration of the audio subsystem. Version 1.18

Known Problems

  • The installer was supposed to be able to keep the screen from locking, but this will still happen after 15 minutes. Please keep the screen active during installation. As a workaround if you know you will be keeping your machine unattended during installation, press Alt-Space to invoke Krunner (this even works from the Install Ubuntu Studio versus the Try Ubuntu Studio live environment) and type “System Settings”. From there, search for “Screen Locking” and deactivate “Lock automatically after…”.
  • An issue exists where Plasma Discover has a race condition when trying to load multiple backends and will not load properly. This may or may not happen and the issue is not 100% reproducible. If Discover does not launch for you, this is why.
  • PipeWire has an issue when bridging to some MIDI controllers that require long SysEx messages, causing those MIDI controllers to not function correctly. FIXED
  • DisplayCal will not launch as it requires an older version of Python. FIXED
  • The new installer does not configure the system’s audio configuration properly. We have a first-login fix in progress. PARTIALLY FIXED, launch Ubuntu Studio Audio Configuration to fix You will be prompted to reboot to apply the fix upon login. Further fixes may be coming soon to eliminate this prompt from being necessary. FIXED
  • Ubuntu Studio Audio Configuration will not let the user switch audio configurations between PipeWire and the old JACK/PulseAudio configuration. FIXED, but not functioning. Still under investigation.
  • Ubuntu Studio uses the same KDE Plasma desktop environment as the official Kubuntu release, and thus, may be affected by some of the same issues. This is also true of the core packages of Ubuntu. You can see their release notes here (Kubuntu) and here (Ubuntu).

*PipeWire is now suitable for Professional and Prosumer needs. However, some users may wish to disable the PipeWire-JACK configuration and use JACKd2 via QJackCTL. This can be done via Ubuntu Studio Audio Configuration. Users can also switch to the classic PulseAudio/JACK configuration, but this is deprecated, discouraged, and unsupported.

Support

Ubuntu Studio 24.04 LTS (Noble Numbat) will be supported for 3 Years until April 2027.
