gitlab.common-lisp.net has recently been migrated and has become pickier about what types of SSH keys it accepts. So if you are using an older keypair (e.g. rsa with less than 2048 bits) then you may need to generate and register a new pair.
Our gitlab now supports the following key types for both SSH login and Git operations:
ED25519: ssh-ed25519, ssh-ed25519-cert-v01@openssh.com
ECDSA: ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521, and their certificate versions
RSA: rsa-sha2-512, rsa-sha2-256, and their certificate versions (Note: RSA keys must be at least 2048 bits long)
Security Keys: sk-ssh-ed25519@openssh.com, sk-ecdsa-sha2-nistp256@openssh.com, and their certificate forms
Older RSA keys with less than 2048 bits are no longer accepted. Please ensure your RSA keys meet this requirement.
How to Update: If you need to update or generate new SSH keys, please follow the instructions provided in the GitLab documentation at:
Generating SSH Keys
Thank you for your coöperation in keeping our infrastructure up to date.
