I just hit this problem while working on a new installation. In the OpenSSH format in version 6.8, the key fingerprint format was changed:
Add the FingerprintHash parameter to ssh (1) and sshd (8) and the equivalent command line flags for other tools to control the algorithm used for key fingerprints. By default, it changes from MD5 to SHA256 and the format is from hex to base64.
Fingerprints now have a hash algorithm. Example new format: SHA256: mVPwvezndPv / ARoIadVY98vAC0g + P / 5633yTC4d / wXE Note that the visual keys of the host will also be different.
The latest git gitolite post has been known since March 18, 15 of this new format.
