Can't delete users in self hosted v3.4.x

[Saul_D]

Continuing the discussion from Delete a user with rails - fails:

Hello,

After following fore mentioned instructions I can’t delete users neither with standard procedure from Docs»Console»Deleting Records.
I become the following message:

irb(main):123:0 ActiveRecord::InvalidForeignKey (PG::ForeignKeyViolation: ERROR: update or delete on table "users" violates foreign key constraint "fk_rails_08966259e8" on table "schedulers") irb(main):124:0 DETAIL: Key (id)=(27) is still referenced from table “schedulers”.

Yes.
The documentation clearly states “delete customers”.

You’re, like in the other thread, trying to remove an (ex) agent or administrator.

Fast forward to now:
Update to Zammad 3.5 and run User.find_by(email: '<email>').destroy and you’ll be fine.

Alternatively you can also use the UI based Data Privacy function that came with 3.5:
