Errore durante il ripristino da riga di comando (duplicato email)

[hosna]

Ricevo questo errore:

ECCEZIONE: psql non riuscito: DETTAGLIO: La chiave (lower(email::text))=({REDACTED}@yahoo.com) è duplicata.

Come posso risolverlo?

Penso che in qualche modo sia correlato a questo:

So many broken users due to corrupt database

I have a real issue with many of my users. The users can be seen in admin panel like this: [Screenshot from 2019-12-12 20-00-31] But when I try to reveal their email address, It wont show anything to me. And also their public profile gives a 404 error. As far as I see, all of these users are almost inactive (they are active in terms of activation but inactive in terms of activity in forum). So I think maybe its been caused by a broken automatic inactive user removal in the very long past.
