To get around this, you just need to edit your ssh_config. I'll use nano in this example.
In terminal, issue: sudo nano /etc/ssh/ssh_config
Enter your password and hit enter
Scroll down until you see this line:
# MACs hmac-md5,hmac-sha1,email@example.com,hmac-ripemd160
Delete the pound sign, which will un-comment that line and make it active.
Hold Control and hit X to exit, hit Y to save, and Enter to apply.
That should do it!
