问题是 24.04 移出/etc/fonts/conf.d/10-sub-pixel-rgb.conf了ubuntustudio-default-settings（前，后）并进入fontconfig-config。该ubuntustudio-default-settings软件包需要先更新，但是维护人员忘记添加自动Conflicts:行。
您可以通过运行 重新尝试以正确的顺序安装软件包sudo apt install --upgrade ubuntustudio-default-settings。如果这不起作用，则需要强制以正确的顺序重新安装：
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
