Ahh thanks! Yes, still unpatched.

It'll soon be upgrading it to 7.7 anyway.

screwed up on my 7.6/octeon

When I ssh from OpenBSD 7.7 to an OpenBSD 7.6/octeon machine I am getting
connection failure with this error:

(last 2 lines of ssh -vv output)

debug2: ssh_ed25519_verify: crypto_sign_ed25519_open failed: -1
ssh_dispatch_run_fatal: Connection to 172.25.101.2 port 22: incorrect
signature

This is a symptom of https://ftp.openbsd.org/pub/OpenBSD/patches/7.6/common/003_ssh.patch.sig

A workaround is to use -o KexAlgorithms=sntrup761x25519-sha...@openssh.com
as part of your ssh command line.
