Саn not delete repository. Why?

I can not delete repository laspavel/lserver.
Why ?

I deleted the problematic repository using a script:

TOKEN=$(curl -s -H "Content-Type: application/json" -X POST -d '{"username": "laspavel", "password": "XXXXXXXXX"}' https://hub.docker.com/v2/users/login/ | jq -r .token)
curl -X DELETE -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/laspavel/lserver/

The issue can be closed.
