How to fix DPKG_LOCKED Cydia Error on iOS 10 and 10.2

Jailbreaking your iPhone is exciting and maybe sometimes problematic at the same time. Interesting because it lets you explore a lot and install Cydia tweaks to customize the user experience, but it gets problematic when you face errors.
Well, it’s not as bad as it sounds since problems always come with their solutions. One of the issues I encountered while jailbreaking my iOS 10.2 was DPKG_LOCKED Cydia error, and I decided to restore my device to fix the problem.
To tell you the truth, I was stupid to do so and restoring isn’t really a solution for all the problems. I followed the below six-steps guide to get rid of the error, and it worked. Try it if you are facing the same issue.
