i don't have cssu thing so i download camera-ui2 manually everytime you update it and move it to /usr/share every update was working but the last one isn't working, cause when i type : root dsmetool -k /usr/bin/camera-ui -----(gives me)-----> process not killed : not found, not root or kill failed /usr/bin/camera-ui2 ------(gives me)-------> permission denied so i did chmod 700, chmod 777 and even chmod +rwx -----(gave me)-----> segmentation fault what could be the problem ?
