Solved ssh between freebsd and linux -- Warning: untrusted X11 forwarding setup failed: xauth key data not generated

I am connecting to a Bhyve VM running Rocky Linux 8 using ssh without passwords. When I successfully connect I nonetheless get the 'untrusted forwarding' error. I am trying to discover on which end of the connection the problem lies. As I do not have this problem when connecting to FreeBSD hosts, whether jails of VMs I infer that the problem lies somewhere in an incompatibility between RL8 and FreeBSD.

Below is an extract of the session setup environment and negotiation:

What is this about?

Try removing the stale entry in known_hosts.
