git push fails: `refusing to update checked out branch: refs/heads/master`

Question

I want to store my local modifications to JBoss config in git. For this, I have set up the following structure:

lrwxrwxrwx  1 jboss jboss        19 Jan 24 11:53 current -> jboss-as-7.1.0.CR1b
drwxr-xr-x 11 jboss jboss      4096 Jan 24 12:13 jboss-as-7.1.0.CR1b
-rw-r--r--  1 jboss jboss 108211143 Jan 23 16:02 jboss-as-7.1.0.CR1b.tar.gz
drwxr-xr-x  6 jboss jboss      4096 Jan 24 11:36 local

local is the git repository which shall be the "origin". The idea is that I want to be able to easily update my JBoss distribution once an update is available. I want to store all local modifications to the distributed JBoss package in git.

So, currently I do this:

jboss@tpl0:~/jboss-as-7.1.0.CR1b$ git init
Initialized empty Git repository in /opt/jboss/jboss-as-7.1.0.CR1b/.git/
jboss@tpl0:~/jboss-as-7.1.0.CR1b$ git remote add origin ../local/   
jboss@tpl0:~/jboss-as-7.1.0.CR1b$ git pull origin master 
From ../local
 * branch            master     -> FETCH_HEAD

So far so good, all my local modifications are there where I want them.

However, once I have local modifications and want to bush them back to the local repository, I get an error:

jboss@tpl0:~/jboss-as-7.1.0.CR1b$ vim standalone/configuration/standalone.xml   
jboss@tpl0:~/jboss-as-7.1.0.CR1b$ git commit -a -m "renamed database to project2_core,   to distinguish from other projects"

What can I do about this? Any help is greatly appreciated!

EDIT

Here's what I did, which solved the problem:

cd ~/current
git init
vim .gitignore                   # set up a basic .gitignore file
git add .gitignore
git commit -a -m "initial commit"
cd ~/local
git clone ~/current
git branch -m master current     # rename master branch to 'current'
git branch repo
git checkout repo

Now, the branch current in directory ~/local is always up-to-date, but it's not cheked out, so that i can push into it.

Pushing is meant for bare repos. For non-bare repos you should pull into them.

If you want to force this through anyway, you can do as the error message states and set receive.denyCurrentBranch to ignore. SSH to the location of the repo you are pushing to and run:

git config receive.denyCurrentBranch ignore
