SOLVED EA3 to 4 migration "is successful", but reverts

Hi!

I'm not the greatest with WHM, but I've made due for years.

Today, I've tried to migrate from EasyApache 3 to 4, and after running the migration tool from WHM (via Software > EasyApache4), but I've run into a problem. Without a clear error message that's explaining why, I revert back to EA3.

I've got the entire text from the migration tool, but I'll only post the log messages bit, in-line. Apologies if it's not enough info.

Code:

I've had no troubles recompiling EA3 as needed over the years, but I'm a bit out of my league on this one. Any help would be greatly appreciated.
