I’ve seen this thread referred to a number of times. Unfortunately there are multiple problems and (possible) solutions in the thread. It would be more helpful at least to specify which fix you think would be most appropriate. I tried all of them and they did not work for the situation that I find myself in here Error upgrade failed OJS 3.1.2-4 to OJS 3.3.0-8 - #2 by jamilj.
That said, it seems like the the changes suggested by @murilodbva are much too extensive for most users to try. IMO, they are suggestions that should be made in github, not here. In the past, fixing one or two errors has had a cascading effect. However, I wonder if the main issue I’m having is the large jump between versions.
It would be fantastic to develop a more seamless update method—i.e., an update tool—that would encourage users to make updates on a more regular basis. Though I realize this is difficult for open source projects in general.
