openssh 8.8p1 (just released in Rawhide) cannot connect to older servers. The error is:
Unable to negotiate with [server] port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss It seems like the cut-off point is RHEL <= 6 broken, RHEL >= 7 is OK. I eventually found a workaround/solution to this deep in an Arch thread: https://bbs.archlinux.org/viewtopic.php?pid=2006291#p2006291 or the equivalent on the command line: ssh -o HostKeyAlgorithms=+ssh-rsa -o PubkeyAcceptedAlgorithms=+ssh-rsa rhel6 Both config options seem to be necessary.
