Using Google Cloud SQL I was attempting to restore my main instance to a prior backup, but first I wanted to clone the instance for the tables and databases that I didn't want reverted.
After waiting over an hour for the clone, I canceled out of the clone and attempted to delete the cloned instance. However, the clone is now stuck in Maintenance status and attempting to delete I get the following error.

```
mycomputer:~ myuser$ gcloud sql instances delete cloned
All of the instance data will be lost when the instance is deleted.

Do you want to continue (Y/n)?  y

ERROR: (gcloud.sql.instances.delete) The instance or operation is not in an appropriate state to handle the request.

```

The instance was created with the following command and then just exited out with CTRL+C after waiting too long.

```
mycomputer:~ myuser$ gcloud sql instances clone main cloned
Cloning Cloud SQL instance.../ERROR: Caught socket error, retrying:[Errno 54] Connection reset by peer
