Gitosis installation error

I am trying to install gitosis on my server but keep getting the error "Username contains not allowed characters"

sudo -H -u git gitosis-init < /tmp/id_rsa.pub

with the username "abhinav@115.118.212.234.static-delhi.vsnl.net.in".

Any fix for this?

I am on a Mac and trying to install gitosis on Snow Leopard.

Update

I changed the username in the public key to abhinav@vindev.net and it worked. Probably it's a problem with the hyphen sign. After installing I tried this

git clone git@vindev.net:gitosis-admin.git
cd gi开发者_StackOverflow社区tosis-admin

but it fails saying

fatal: 'gitosis-admin.git': unable to chdir or not a git archive

Any ideas about what I may be doing wrong?

This is the guide I followed: http://nfocipher.com/index.php?op=ViewArticle&articleId=12&blogId=1

Is this related to the public key format, as described in this thread?

(I know it refers to a Window installation and you are on a Unix server, but the idea remains valid)

I figured that PuttyGen had generated an SSH2 public key file in a slightly different format, and ‘git gitosis-init’ wanted a user name at the beginning, so I went here:

http://www.rfc-archive.org/getrfc.php?rfc=4716

and saw that I could keep the “--BEGIN…” and “--END” parts, and replace the “comment: ...” line (generated by PuttyGen) with a line reading:

subject: git

And it worked! I got the output:

Initialized empty Git repository in /home/git/repositories/gitosis-admin.git/
Reinitialized existing Git repository in /home/git/repositories/gitosis-admin.git/

You can also try to copy just the key, as in this thread:

It's work fine for my ssh-pubkey on rawhide. I assume you have the wrong file format.
Try to copy id_rsa.pub key only (without comments, etc), run sudo -H -u gitosis gitosis-init, paste pubkey, then ^D.

Had same problem. Turns out it was because username started with a number.

Had the same problem. My issue was an '_' in the name of my computer.
