I messed up the Update(s) by missing them, some advice needed

Hello,
I am at version 3.71 and I am not able to update following the Official guide, as the installation fails when going for the latest update.

OS: Debian 9.7

Here is my question, does it help to do update after update?
If yes, how to figure out which updates need to be done and how to get URL for the file?
