Do you really want to force-unlock?
  Terraform will remove the lock on the remote state.
  This will allow local Terraform commands to modify this state, even though it
  may still be in use. Only 'yes' will be accepted to confirm.

  Enter a value: yes

Terraform state has been successfully unlocked!

The state has been unlocked, and Terraform commands should now be able to
