Problem
After dreamhost decided to move my account that hosted the git repository to a new server, first time I’ve tried to push some changes to the git repository I was faced with the followng error:

Counting objects: 13, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (7/7), done.
Writing objects: 100% (7/7), 699 bytes, done.

error: refusing to update checked out branch: refs/heads/master
error: By default, updating the current branch in a non-bare repository
error: is denied, because it will make the index and work tree inconsistent
error: with what you pushed, and will require 'git reset --hard' to match
error: the work tree to HEAD.
error:
error: You can set 'receive.denyCurrentBranch' configuration variable to
error: 'ignore' or 'warn' in the remote repository to allow pushing into
error: its current branch; however, this is not recommended unless you

To ssh://dh_user@dh_domain/home/repository_path/projects/project.git

Solution
After searching and finding out various solutions to solve the problem, none of which was specific to a server move, I’ve tried the following:

  • Followed the steps here to set up a new repository project_asm.git
  • went to local project changed the config file to add the new remote repository
  • issued git push new_remote master
  • make a code change and then git push

And everything should work as normal again.

Deploying a Rails project in a server that hosts the git repository

Problem
You want to deploy your project in a server (dreamhost), that also hosts your git repository. When you try to do that by only setting the set_repository, you get errors like ‘permission denied, please try again’, even though if you try to checkout the git repository on your server works.

Solution
Set your :repository as a file in your host as in:
set :repository, "file:///home/username/git_on_server/projects/repo_name.git"

Then also set up your local_repository, as in:
set :local_repository, "user_name@server_domain_name:/home/username/git_on_server/projects/repo_name.git"

Getting your Github git project to dreamhost

Problem
You already have a project in github, but you want to move it to a different host (ie dreamhost)

Solution
Following the post here that describes how to setup a new git repository in dreamhost, the only difference after the initial setup :

ssh username@dreamhost_domain.com

mkdir -p ~/git/yourproject.git

cd ~/git/yourproject.git

git --bare init

is to edit your project’s .git/config file:
vi local_host/your_project/.git/config

and change the :
url = git@github.com:user_name/project_name.git

to the following:
ssh://dreamhost_username@dreamhost_domain/~/git/yourproject.git

Lastly you have to push for the first time to the server:
git push origin master

Optionally if you would like to check and/or checkout to a different pc you can use:
git clone ssh://dreamhost_username@dreamhost_domain/~/git/yourproject.git
