Error when running sudo checkinstall

[nsshub]

I follow instruction to compile from this link. https://askubuntu.com/questions/1003678/install-dnscrypt-proxy-gui when I reach the next command which is sudo checkinstall, I got error from terminal such bellow :

**** Installation failed. Aborting package creation._

Restoring overwritten files from backup...OK

Cleaning up...OK

Bye. `

by the way I have installed dependencies exactly like the instruction said.

Can you help me to solve this problem ?

It related with Qt version... you have version older than 5.14 Looks https://doc.qt.io/qt-5/qt.html#SplitBehaviorFlags-enum

To make it works on Ubuntu 20.04 LTS without upgrade Qt to 5.14: rm -rf src/helpers/test_helper/ and remove add_subdirectory(test_helper) from src/helpers/CMakeLists.txt before sudo cmake ./
