Hi! Im trying to install polkit-dumb-agent and its not working. It used to work fine a few weeks ago.

Every time i try installing it whether it is with aur helpers or manually i get an error like this:

Any help is appreciated!!

CMake Error at CMakeLists.txt:6 (find_package):
By not providing "FindKF5Su.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "KF5Su", but
CMake did not find one.

Could not find a package configuration file provided by "KF5Su" with any of
the following names:

KF5SuConfig.cmake 
kf5su-config.cmake 

Add the installation prefix of "KF5Su" to CMAKE_PREFIX_PATH or set
"KF5Su_DIR" to a directory containing one of the above files. If "KF5Su"
provides a separate development package or SDK, be sure it has been
installed.

I don't know what am I doing wrong, but no matter what, I cant get any polkit to work properly. I'm on Debian 12, and I've tried these three polkits:

fpp@fpp-asus:~$ pgrep -l pol

I honestly dont know what is wrong. I use Ly as my display manager. I've only once got lxqt-policykit-agent to work, but it wasnt on this computer, and it had the same issues as I have now, and some day it started working fine. Ideally, I would like to avoid having to use lxqt-policykit-agent, because I have Gnome installed, and I dont really like mixing different DE's packages... polkit-dumb-agent was my first choice, but I'm not completely sure if it works on wayland
