Open /etc/ssh/ssh_config via a Linux editor like vi, vim, nano, ne or etc
Example: #sudo nano /etc/ssh/ssh_config
Copy the following to the top of the ssh_config file (anything with a "*" wildcard in it has to be last):

Host <IP / Host Name>
    User <your username>
    PubkeyAcceptedAlgorithms +ssh-rsa
    HostkeyAlgorithms +ssh-rsa
    Ciphers aes128-ctr
    KexAlgorithms +diffie-hellman-group1-sha1       #(or whatever the cipher it asks for)
