STEPS TO REPRODUCE
1. Open Konsole in KDE neon 5.27
2. Follow the steps to create "develpment environment" mentioned here
https://community.kde.org/Get_Involved/development/Set_up_a_development_environment
3. Follow the steps to "build software with kdesrc-build" mentioned here
https://community.kde.org/Get_Involved/development/Build_software_with_kdesrc-build
4. After building kcalc succesfully and fixing various dependencies with
'kdesrc-build workspace', the process stops in the 'Discover' application
OBSERVED RESULT
