Thank you for updating the documentation, that's exactly what was misleading.
Just as a feedback: installing manually the metapackages listed in the ubuntustudio-installer worked fine. The ubuntu-desktop metapackage was probably automatically uninstalled (it is no more instlled in my system), but during the manual installation process I did not notice any removal of other critical system packages. So now I have an Ubuntu Studio over a Vanilla Ubuntu Gnome, with pulse-audio + jack, and a low latency kernel. To me, your answer closes the issue. Thanks a lot. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/2033440 Title: ubuntustudio-installer: error occurred while applying changes Status in ubuntu-meta package in Ubuntu: New Status in ubuntu-meta source package in Lunar: New Status in ubuntu-meta source package in Mantic: New Bug description: I have installed successfully the standard Ubuntu 23.04 (on a 500 GB external USB drive). Immediately after the installation, I have also installed with apt the "ubuntustudio-installer" package. In the dialog provided by the ubuntustudio-installer, I have selected the following metapackages: - linux-lowlatency - ubuntustudio-lowlatency-settings - ubuntustudio-performance-tweaks - ubuntustudio-audio - ubuntu-pulseaudio-config and pressed "Modify installed Package Selection" After a while a "qaptbatch" dialog has appeared with title "Commit Error" and message "An error occurred while applying changes" So the installation has failed. Then I have tried to manually install each metapackage in the list above with apt and every package was installed successfully.
