Getting Ubuntu Studio 20.04 LTS

Download a Disk Image

Upgrading to Ubuntu Studio 20.04

NOTE: Upgrades to Ubuntu Studio 20.04 LTS from 19.10 are enabled anywhere from a few days to a few weeks after release. Upgrades to Ubuntu Studio 20.04 LTS from 18.04 are enabled after the first point-release (20.04.1), which will be in August.

If you have enabled the Ubuntu Studio Backports PPA, be sure to remove it.

To remove the Backports PPA, open a terminal window and type:

 sudo apt install ppa-purge
 sudo ppa-purge ppa:ubuntustudio-ppa/backports

If for whatever reason this PPA removal fails, continue with the upgrade as usual.

To upgrade:

Open a terminal and type the following:

 sudo do-release-upgrade

Follow the instructions in the terminal.

Changes for this release (compared to 19.10 Eoan Ermine)

  • The package/metapackage selection screen has been removed from the Ubiquity (live session) installer due to a bug which caused unwanted packages to be removed.


  • Ubuntu Studio Controls has been upgraded to Version 1.12.4. Many changes have been made for the Eoan Release, and the following is a summary of some of those changes:

    • Audio setup tab is split into three tabs: Jack Master Settings, Extra Devices, Pulse Bridging
    • Firewire devices are no longer available under Ubuntu Studio Controls unless they work with ALSA. Consider upgrading to a modern USB or PCIe audio interface to take advantage of everything Ubuntu Studio Controls has to offer.
    • PulseAudio bridges can now be named by the user

    • Multiple bug fixes
    • For more information about Ubuntu Studio Controls, see:

Current Version Of Main Multimedia Packages

Known Problems

  • An issue has been identified with the ristretto image viewer in which blue "scroll for more" indicators appear within the window, partially covering the image even when the entire image is visible. This is most obvious in the default Ubuntu Studio theme (Materia), but has been identified in other themes and is therefore a bug with ristretto.

  • Ubuntu Studio uses the same XFCE desktop environment as the official Xubuntu release, and thus, may be affected by some of the same issues. This is also true of the core packages of the mainline Ubuntu release. You can see their release notes here (Xubuntu) and here (Ubuntu)

  • Timidity (not installed by default) has been known to cause problems with audio configurations on Ubuntu and will lock-up ALSA.
  • The Ubiquity Installer currently has an issue in which, if selecting auto-resize, you may experience black text inside of black boxes for the partition allocation. One workaround is to change the Xfce theme to a different theme if you wish to auto-resize partitions, e.g. you have another operating system already installed.


Ubuntu Studio 20.04 LTS (Focal Fossa) will be supported for 36 months (3 years) until April 2023. Users of Ubuntu Studio 19.10 and 18.04 are urged to upgrade at their earliest convenience.
