No matter what I do, the SSH portion fails with "permissions denied" or other similar errors.
I've set up an elastic IP and used that also in the ssh string below.
I created a new key-pair pem file in "~" called ubuntu-fms.pem
When creating the 18.04 image in AWS, I named it also "ubuntu-fms".
Then, when ssh-ing...
$ ssh -i ~/ubuntu-fms.pem ubuntu-fms@<elastic_ip_here>
I've tried several times with new key pairs, new instance names, etc., but I can't log in using ssh to get started.
Can anyone see what I'm doing wrong?
The only suggestion I found online was to do a chmod 600 on the pem file, which I did, but made no difference.
Thanks in advance.
I suppose you started the ssh server on your ubuntu ?
In the tutorials I used users were encouraged to create a (on mac OS at least) hidden directory ~/.ssh where later the keys are stored
the one step setup than could be:
sudo ssh-copy-id -i ~/.ssh/yourKey.pub adminuser@yourIP
this copies the ssh key from your directory ~/.ssh to the admin users ~/.ssh directory and if .ssh does not exist it is created on the fly...
Btw why use a 18.04 instead of 20.04 - or is it for an older FMS?

Thanks!
I got SSH working.
The demo I was using is using 18.04. Is 20.04 supported now officially?
If so, I'll have to start over (noch ein mal) ... (sigh).
Thanks H.
Fortunately, I was able to upgrade Linux using the sudo apt update type commands. 
Now trying to get things the command console working (my mistakes, probably). I'll post back with updates.
Thank you, H.
