Kubuntu-backports has version 5.47.0 of every libkf5* package except for libkf5config-bin-dev which is only available in version 5.46.0. Where do I get libkf5config-bin-dev_5.47.0 ? Without it I cannot install qttools5-dev and without qttools5-dev I cannot compile qt5 software, e.g., falkon 3.0.1 -- all because I cannot locate version 5.47.0 of a single package in a family of packages in which every other package is at version 5.47.0. Thank you in advance for any and all replies. jay at m5 dot chicago dot il dot us

Looks like they changed bin-dev to dev-bin for 5.47.0: https://salsa.debian.org/qt-kde-team.../changelog#L72

Thank you for your most useful reply. I located the .deb file with the new name, downloaded it, and upgraded the package -- more precisely, I could not upgrade the package, I had to manually remove libkf5config-bin-dev and then manually install libkf5config-dev-bin. This satisfied the dependency requirements of the other packages I wanted to install and I was then able to install them all. I was then able to achieve my ultimate goal, which was to run cmake in the falkon source directory (although it complained about not being able to find certain optional packages) and then I was able to build and install falkon 3.0.1.
