I'm trying to deploy to a new ubuntu 14.04 box with cap staging deploy, but capistrano hangs during the git:check task:
GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/<app_name>/git-ssh.sh /usr/bin/env git ls-remote --heads git@github.com:<github_user>/<app_name>
Why is this happening?
Turns out, this was due to having changed the port number of ssh in /etc/services
Debug steps in case others have similar problems:
First I ran:
GIT_CURL_VERBOSE=1 GIT_TRACE=1 git ls-remote git@github.com:<github_user>/<app_name>
In the debug, the following line was hanging:
trace: run_command: 'ssh' 'git@github.com' 'git-upload-pack '\''<github_user>/<app_name>'\'''
Then I tried:
ssh -vvv git@github.com
and in the debug I saw that ssh was trying to connect to a non standard port.
