ICX7150-12 with 08.0.90T213 firmware unable to upgrade FW with SSH

After adding diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 key exchange to my ssh server the switch now reports "User Authentication failed", which it did not before enabling the diffie-x key exhange protocols.

What ciphers are supported on modern Linux's that I can enable to do an update to 9x?

 

Thank you

Downloaded ubuntu 16.04 and it had old enough ssh to allow ssh connectivity.  So problem solved
