I thought this is the error with the git on server.I have updated it but no still no success. I ssh to server and tried to run git ls-remote -h command directly

DEBUG[d6b0ae0e] Command: ( GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/zarapp/git-ssh.sh /usr/bin/env git ls-remote -h  )
DEBUG[d6b0ae0e]     usage: git ls-remote [--heads] [--tags]  [-u <exec> | --upload-pack <exec>]
DEBUG[d6b0ae0e]     
DEBUG[d6b0ae0e]                          [-q|--quiet] [--exit-code] [--get-url] [<repository> [<refs>...]]

it also says the same output. Is the capistrino 3 is running the wrong syntax for command or there is some other issue ?

Answer 1

git ls-remote needs a repo to operate on.

that means:

• git ls-remote -h will always fails

• but this would work:

    git ls-remote -h /local/path/to/a/repo git ls-remote -h origin 

---

As the OP Hemc comments : " capistrano - git ls-remote -h doesn't have the git url " does point out to a capistrano version mismatch (2.x vs. 3.x)

See " Preparing Your Application "

The deploy.rb is a place where the configuration common to each environment can be specified, normally the repository URL and the user as whom to deploy are specified here.

set :application, 'my app name'
    set :repo_url, 'git@example.com:me/my_repo.git'
    ask :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }

The git ls-remote will use repo_url for its execution.
