<div>Extension install / upgrade error: The role wasn’t found for the user. Verify the role and try again</div>

I have migrated an M1 system to M2 and all seems to have gone well.

My problem comes to installing or updating extensions. I get the error:

Running schema recurring…The role wasn’t found for the user. Verify the role and try again.

The outcome is that extensions fail to create attributes they may rely on and the database column ‘data_version‘ in the ‘setup_module‘ table fails to be updated.

I have checked log files and don’t see anything obvious related to this so am totally stumped.

Has anyone come across this before? I have seen similar issues but not this particular one.

Any help appreciated
Andy
