Raoul's answer to his own question is correct. I ran into the same issue and adding the correct algorithm name after the `-m` option works (in my case the option was `-m hmac-sha2-512` to connect from PowerShell to a machine running Ubuntu 18.04).

I wasn't sure which algorithm to use, but you can list all the available ones by running:


ssh -Q mac


I selected one at random, tried it and the remote server returned saying that algorithm wasn't supported, but it handily told me which one's were so that I could amend my command. Using this command I could then ssh into the remote machine:

ssh -m hmac-sha2-512 <user_name>@<remote_address>



If you need to use `scp` too, the parameter is different:

scp -o MACs=hmac-sha2-512 <and the rest of your scp command>

You can add this to you ~/.ssh/config also:
Host name
    Hostname <fqdn>
    IdentityFile ~/.ssh/<key-file>
    User <username>
    MACs hmac-sha2-512
