Git SSH public key authentication failed with git on Azure DevOps

Question

I am trying to push a git repo from PowerShell into an Azure DevOps repo, and I keep getting different auth errors when trying to push it.

I am hoping somebody can shed some light on what I check, and do a proper walkthrough.

E.g.,

git remote add origin [email protected]:v3/MyAzure/MyProject/MyRepo git push -u origin --all 

I keep getting:

[email protected]'s password:

I've input all sorts of passwords, but it's still failing. Which password is it talking about?

Alternatively, I've also gotten:

Permission denied, please try again.

fatal: Could not read from remote repository.

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

Verification:

$ ssh -T [email protected] ssh: connect to host mycompany.com  port 22: Connection refused 

I have done the following:

• Created a repo in Azure DevOps
• Created a SSH key using git-bash, as per Microsoft's documentation, copied and pasted without spaces into Azure DevOps security.
• Gone to my profile/security and added an SSH key (generated in git-bash)

Am I missing the obvious? Is it better to use personal access token? Can anyone provide a walk through of the correct steps?

Answer 1

This worked for me

adding a config file in ~/.ssh/

and adding these lines

Host ssh.dev.azure.com IdentityFile ~/.ssh/my_ssh_private_key IdentitiesOnly yes
