+=====Unable to Negotiate  =====
+I found the following when trying to SSH from Ubuntu 22.04.4 to Palo Alto Networks Firewall running PAN-OS 11.0.0
+<code>Unable to negotiate with <IP> port 22: no matching host key type found. Their offer: ssh-rsa,ssh-rsa,ssh-rsa</code>
+To make it work, I had to add the following at the end of the SSH command in Ubuntu
+<code>-o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedAlgorithms=+ssh-rsa</code>
