Dear Arch DevOps Team, Following the migration of our GitLab instance from a cloud server to a new dedicated box, you will need to remove the old host keys from your $HOME/.ssh/known_hosts file. For this please do: ssh-keygen -R gitlab.archlinux.org After the above, when you attempt to connect to gitlab.archlinux.org, you will be prompted to accept a new host key. Please find below the new host key fingerprints: SHA256:ZHy7zbNNwKHukTEyFcAT2Ns+mT/wlc2vAjJULnlOroE (ECDSA) SHA256:KD3Og7bPg9glmODrqUKN0r3Jl18pQ0OVp2MT7xv/bm8 (ED25519) SHA256:2R7QoVWeZ2DpKEsZBgVKUieM+9TQu6g9N62CIJCyVtc (RSA) Please note that this change only affects the host machine and not GitLab itself. Git clones from the latter will work without change. Stay safe and frosty!
