I installed gitlab on my servers at linode. All services of gitlab are working fantastic. I am able to login, create users, repos etc. But the problem I am facing is when I try to push a repo it prompts a password for the git user as follows:

[email protected]'s password

I have followed the instructions of installing gitlab at: https://github.com/gitlabhq/gitlabhq/blob/master/doc/install/installation.md and have disable the login got the user git using the following line mentioned in the installation guide:

sudo adduser --disabled-login --gecos 'GitLab' git

I am using gitlab version 6. What could be the problem?

The output of: ssh -Tvvv [email protected] is as follows:

I had the same problem but it was because my server only accept ssh login from users of "sshusers".

On /etc/ssh/sshd_config I had the following line :

AllowGroups sshusers

In order to fix this issue, I added git to sshusers group:

$ sudo adduser git sshusers 

And then it's working.

That should only mean that:

  • either the public ssh key was incorrectly registered in the user account

https://intranet.5amsolutions.com/download/attachments/24610136/Git3.png?version=1&modificationDate=1349371375213

  • and/or the public/private ssh keys aren't accessible from the user account (~/.ssh incorrectly protected, incorrect names different from id_rsa, id_rsa.pub, incorrect ~/.ssh/config file).
    See more, for instance, at "Git SSH authentication".

The OP swaroopsm comments:

I solved the issue by re-installing gitlab on the server. Now all is fine.

I had a similar problem when I set the remote repository with the HTTP URL.

I changed it to use the SSH URL, and it worked fine:

git remote set-url gitlab [email protected]:niccolox/cirm-website.git

In my case, I had to add the remote repository with ssh as

git remote add gitlab ssh://[email protected]:222/git/repo_name.git 

which made git not request me the password again. Note the use of ssh:// and port=222.

On systems with SELinux enabled you should not disable SELinux as suggested in some answers.

To get along with the SELinux restrictions (iff they are the reason for the password prompt; check your /var/log/audit/audit.log ) change the security context for gitlab:

chcon -t user_home_dir_t /var/opt/gitlab/
chcon -t ssh_home_t /var/opt/gitlab/.ssh/
chcon -t ssh_home_t /var/opt/gitlab/.ssh/authorized_keys

(as suggested at the gitlab group)

To properly fix the selinux issues, use the following. Note that chcon is only temporary and will not survive a relabel or restorecon, so you should use semanage instead.

semanage fcontext -a -t user_home_dir_t "/var/opt/gitlab(/.*)?"
semanage fcontext -a -t ssh_home_t "/var/opt/gitlab/.ssh(/.*)?"
restorecon -rv /var/opt/gitlab

I tried many options but no success. The only that resolved for me was osxkeychain helper

See the tutorial here.

The tutorial is from github, but works great for gitlab too.

I had same issue. Mine was that SELinux was enabled. Please disabled SELinux here is the link http://www.how2centos.com/disable-selinux-centos-6/
