Now I am not getting libqt5webchannel.so.5 missing error (which is dependency of qt webkit) in Ubuntu 16.04.
Till now I was using Ubuntu 14.04 compatible debian/rule file in Ubuntu 16.04 machine during creating debian package.
I just made changes in debian/rule file as per Ubuntu 16.04 and it works. But I did not know how to install qt5webchannel in Ubuntu 16.04.
