Thank you for taking the time to report this bug and helping to make Ubuntu (Studio) better.
@Bluesbrother (or the original posted to askubu..) Can you please add what your installation media was, ie. `cat /var/log/installer/media-info` as your original post on askubu implies you release-upgraded to noble, and thus this issue may only occur on upgrades, rather than fresh installs. Ideally an `apport-collect` would gather this (& more details), but you aren't the original report of this bug report. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fontconfig in Ubuntu. https://bugs.launchpad.net/bugs/2051313 Title: font-config confilcts ubuntustudio-default-settings upgrading from 22.04 to 24.04 Status in fontconfig package in Ubuntu: Confirmed Status in ubuntustudio-default-settings package in Ubuntu: Confirmed Bug description: This bug was migrated from https://askubuntu.com/q/1501240/1004020 . A nearly identical bug is https://bugs.launchpad.net/ubuntu/+source/fontconfig/+bug/2005124 . It fixed things for `kubuntu-settings-desktop` but not `ubuntustudio- default-settings`. Please add an analogous fix. A similar but potentially unrelated bug is https://bugs.launchpad.net/ubuntu/+source/ubuntustudio-default- settings/+bug/2037471 . 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu Not my computer. 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center Not my computer. 3) What you expected to happen The AskUbuntu user's upgrade from 22.04 to 24.04 to complete successfully. 4) What happened instead The upgrade failed and they posted to AskUbuntu. # Copy of their question body After an upgrade to ``` Distributor ID: Ubuntu Description:Ubuntu Noble Numbat (development branch) Release: 24.04 Codename:noble ``` apt won't update bcs of unmet dependencies. ``` The following packages have unmet dependencies: libfontconfig1 : Depends: fontconfig-config (>= 2.14.2-6ubuntu1) libfontconfig1:i386 : Depends: fontconfig-config:i386 (>= 2.14.2-6ubuntu1) E: Unmet dependencies.

The `ubuntustudio-default-settings` package needs to be updated first but the maintainers forgot to add an automatic `Conflicts:` line. You can retry installing the package in the correct order by running `sudo apt install --upgrade ubuntustudio-default-settings`. If that does not work, you need to forcibly reinstall things in the correct order: ```bash sudo -i apt update apt download ubuntustudio-default-settings apt download fontconfig-config # Temporarily force-uninstall only ubuntustudio-default-settings # so that we DON'T uninstall ubuntustudio-desktop dpkg --force-all -r ubuntustudio-default-settings dpkg --force-all -i ./fontconfig-config_* dpkg --force-all -i ./ubuntustudio-default-settings_* dpkg --configure -a apt --fix-broken install apt upgrade apt dist-upgrade ``` # Analysis Please apply an analogous fix. Where I mentioned `Conflicts:` on AskUbuntu, a `Pre-Depends:` may be necessary instead as I read somewhere on Launchpad.
