openssh update broke connectivity

I need to find out which are the strong ciphers and use one of them to 
generate a key set.  Even so, I'm on not and I 
cannot update my authorized-keys file with keys using a different cipher 
using ssh-copy-id.  I'll have to use garden variety ftp to do the update 
this time. On Mon, 17 Aug 2015, Tony Baechler wrote:
