After some initial problems I finally managed to save a copy of my app to my local repository, but when I tried the 'cap deploy:setup' command I got the following error.
* executing `deploy:setup'
* executing "umask 02 && mkdir -p /home/<usr_name>/apps/<app_name> /home/<usr_name>/apps/<app_name>/releases /home/<usr_name>/apps/<app_name>/shared
/home/<usr_name>/apps/<app_name>/shared/system /home/<usr_name>/apps/<app_name>/shared/log
/home/<usr_name>/apps/<app_name>/shared/pids"
servers: ["<my_domain>.tertullian.hostingrails.com"]
connection failed for: <my_domain>.tertullian.hostingrails.com (SocketError: getaddrinfo: no address associated with hostname.)
Any ideas.
