Your curl isn't getting installed although the process is getting completed (look at the last 3 lines). The error code 403 as rightly pointed out in the comments, and thus either the server is down for maintenance or you're trying to access internet through a proxy that is not allowing you to do so.
This is why it's showing curl not not found!
