Summary:
I have two accounts (account A and account B) with gitlab.pavlovia.org 1. The gitlab organization I’m working with requires SSH key authentication. I set up authentication for account A without issues. I then went to set up authentication for account B and persistently encountered the error “Permission denied (publickey,password).” When I cleared my .ssh file, and removed all the connections from ssh-add then re-added account A, I encountered the same error. I’ve tried clearing all the files (including known_hosts) and starting over multiple times, but the error is persistent.
Here’s a description of the initial steps I followed:
https://gitlab.pavlovia.org/help/ssh/README.md
To outline things exactly, I first created the key using the command:
ssh-keygen -o -t rsa -b 4096 -C "EMAIL"
I named the key id_rsa_gitlab_pavlovia, and set the password to just enter.
I then changed permissions using:
chmod 600 id_rsa_gitlab_pavlovia*
I copied the key using:
pbcopy < id_rsa_gitlab_pavlovia.pub
and used that to register in my gitlab account.
I then started the ssh agent locally with
eval "$(ssh-agent -s)"
and added my key using,
ssh-add ~/.ssh/id_rsa_gitlab_pavlovia
When I used the command:
ssh-add -l
It showed an active key.
I also set up a config file,
# Pavlovia GitLab instance
Host gitlab.pavlovia.org
Preferredauthentications publickey
IdentityFile ~/.ssh/id_rsa_gitlab_pavlovia
Then, when I try running:
ssh -v -T [email protected]
I persistently get the following error. Keep in mind, I’ve tried clearing all the keys and associated files and starting over multiple times, but continue to get the error.
