The shutdown part of the reboot took about 2hours, I should have probably issued shutdown -r -t00, after reboot I installed the update, it asked for another reboot, this time much quicker and voila, we have the green tick!!
Thanks a lot yet again, Maxstar, have a lovely weekend!!!
P.S. I tried to apply for your academy, but did not get no response from anyone. Is there a long waiting time?
