Permission denied when I try to push from local to remote gitlab repository

Question

I have created a repository in gitlab web ui and tried to push my local repository. I added remote repo using the following command:

$ git remote add origin [email protected]:project.git

Then I tried to push but it errors. I don't use ssl. I want to use plain text connection.

$ git push origin master
[email protected]'s password:
Permission denied, please try again.
[email protected]'s password:
Permission denied, please try again.
[email protected]'s password:
Permission denied (publickey,password).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Answer 1

Then I created the test user from web ui. and created the project with the test user.

You would never use that user for contacting a server in ssh: all the authorized keys are grouped under one account, which for gitlab should be git: ~git/.ssh/authorized_keys

See config/gitlab.yml.

So try:

git remote set-url origin [email protected]:project.git

Answer 2

Newer versions of ssh also disallow DSA key use by default. Make sure you're using RSA keys or make sure your ~/.ssh/config or /etc/ssh/ssh_config files permit DSA keys. You can do this by adding something like this to the appropriate file:

Host your.git.server
    KexAlgorithms +diffie-hellman-group1-sha1
    HostkeyAlgorithms ssh-dss,ssh-rsa

This one bit me.
