The DigitalOcean team has taken steps to address a potential issue with SSH host keys on Ubuntu-based systems created from snapshots. Due to the snapshot and creation process, some host keys may have been duplicated, leading to security concerns. To mitigate this, DigitalOcean's system now removes host keys on Droplets created from snapshots at the first boot, provided there is high confidence that host-keys will be regenerated on boot. Users of existing Ubuntu-based Droplets and snapshots are advised to regenerate their SSH host keys by removing potentially duplicated host keys and generating new ones using a dpkg-reconfigure script or manual key generation commands if necessary.
