SUMMARY libqt6svg6-dev seems to have been renamed to qt6-svg-dev somewhere between Ubuntu 22.04 LTS and 23.10: - https://packages.ubuntu.com/search?suite=all§ion=all&arch=any&keywords=libqt6svg6-dev&searchon=names - https://packages.ubuntu.com/search?keywords=qt6-svg-dev&searchon=names&suite=all§ion=all The same seems to be true for Debian. STEPS TO REPRODUCE 1. From a clean Ubuntu installation, run kde-builder --install-distro-packages OBSERVED RESULT === install-distro-packages === Fetching remote changes to sysadmin-repo-metadata Merging sysadmin-repo-metadata changes from branch master - Installing system packages for ubuntu... Installing packages for debian/24.10 Using installer for debian * These packages were not found in repositories: libqt6core5compat6-dev libqt6opengl6-dev libqt6shadertools6-dev libqt6svg6-dev libgpgme11-dev EXPECTED RESULT It should find qt6-svg-dev instead of libqt6svg6-dev.
The same seems to have happened to libqt6core5compat6-dev - now there is qt6-5compat-dev
kde-builder seems to be tracking its issues at https://invent.kde.org/sdk/kde-builder/-/issues, so it is better to file a bug there instead.
