Using Drush on shared hosting without `curl` and `wget` I have a Drupal 7 site installed on shared hosting. 

And installed Drush:8.1.17 with composer and cgr all is working well except drush up because hosting provider does not support curl or wget on shared accounts. 

When I ask them they said that there is no plans for giving permissions on shared account users to curl or wget when I run:

$ drush up  
$ wget nor curl executable found.

$ curl
-jailshell: /usr/bin/curl: Permission denied


Is there another way of using drush up?
Your use case is not supported. You'll have to update locally and then push to your provider.
