Condition

Trying to set up git on assembla and push the repository there by following this instructions.
Note there is an error on the page (at least in my case) git-commit should be "git commit"

Problem

git push origin master

Following problem occurs:

git@git.assembla.com's password:

Permission denied, please try again.

None of the passwords work, etc.

Solution

This problem seems to be caused by ssh expecting the key in the file named id_rsa

Follow the instructions at http://github.com/guides/providing-your-ssh-key

When prompted for a file-name just press enter without entering the file-name (will default to id_rsa)

To test wheter it works or not execute (as suggested by this post):

ssh -v git@git.assembla.com

Should see:

debug1: Authentication succeeded (publickey).

Now executing this should work:

git push origin master
