Question 194898 in Plesk Question posted in
The official documentation for Plesk Obsidian can be found here.

Plesk Error: Public key for the server at 'bitbucket.org' is already known in '/var/www/vhosts/DOMAIN/.ssh/git_known_hosts'

My attempt:

ssh-keygen -f /var/www/vhosts/DOMAIN/.ssh/git_known_hosts -R bitbucket.org
curl https://bitbucket.org/site/ssh >> /var/www/vhosts/buchungsformular.spar-mit.com/.ssh/git_known_hosts

But I still cannot clone my repository.

Some detailed error messages from plesk:

1.

Expected the repo to work again.

    I needed to specify IdentifyFile .ssh/id_rsa and UserKnownHostsFile .ssh/git_known_host in the ~/.ssh/config file.

    The SSH Key by design is generated by the Plesk git extension on a subscription level, instead of a domain, therefor adding the same keys to a different repository in GitHub will result in this error. Resolution:

    1- Log in to GitHub
    2- Remove the SSH key from the repository that is using this SSH key
    3- Add the SSH key to your GitHub account: add it to your account
