Test on Lenovo MIIX320-10ICR 1. Remove ubuntustudio-controls with: "dpkg --remove --force-depends ubuntustudio-controls" 2. Package removed with keeping the dependencies.
This is important! You lose all packages dedicated with "ubuntustudio-controls". "ubuntustudio-installer, ubuntustdudio-desktop, etc.." if you not keep this dependencies. Reinstalling the "ubuntustudio-controls" from proposed wan't reinstall them again. 3. Added "focal-proposed" to "/etc/apt/source.list". Update executed with: "apt-get update" 4. Created "/etc/apt/preferences.d/proposed-updates" (See EnableProposed Wiki) 5. Install from focal-proposed: "apt-get install ubuntustudio-controls/proposed" 6. "ubuntustudio-controls (1.12.5~20.04.1)" No problems with the installation. 7. Started "ubuntustudio-controls" from the desktop. Starts without errors. 8. Selected Audio Setup / Jack Master Settings 9. Jack Master Devices (no USB) dropdown list shows all audio devices as required. Same testing on another machine where all audio drivers already had a description: No problems with the new version "ubuntustudio-controls (1.12.5~20.04.1)". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872187 Title: [SRU] ubuntustudio-controls crashed with IndexError in refresh_dropdowns(): list index out of range To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-controls/+bug/1872187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
