16.04: No ECDSA host key is known for XXXXX and you have requested strict checking.

[Josef Wolf]

Hello,

when connecting from machines with older ssh releases, I get the error
mentioned in the subject.

I have abondoned DSA keys because they can easily be compromized. ECDSA is
told to have similarweaknesses as DSA.

I undersand that ec25519 is noo new for older clients. But why won't they fall
back to the RSA key that is also available?
