Fail to update macOS: Unable to verify software update

I have been fighting this issue for quite a long time, since I bought a new Mac mini early this year and restored the system with my TimeMachine backup, every time when there is a Mojave update comes out, I always got this “update failed” warning.

Unable to verify software update

“Chrome keeps crashing on MacOS Mojave 10.14.5”

Good job Google!

Because I just did a backup last week for updating 10.14.5, so there is not so much to do another backup during this week. I decide to directly boot into Recovery Mode (Start your Mac, press and hold Command+R), and reinstall MacOS from there. (Please reserve about 30+ GB disk space)
