Not directly, but libssh (partly) read your ssh config. So you can

Are you quite sure? With the following in my ssh config file
Host example.com
PubkeyAcceptedAlgorithms +ssh-rsa
HostKeyAlgorithms=+ssh-rsa
I can run ssh on the command line successfully but trying to start an x2go
session results in
kex error : no match for method server host key algo: server [ssh-rsa,ssh-dss],
client [rsa-sha2-512,rsa-sh

k-ecdsa-sha2-nistp...@openssh.com]
Does x2go actually use the system ssh executable (e.g. /usr/bin/ssh)?
The reason I'm asking is because I did an experiment and renamed
ssh to xxx. I got the same result, shown above, when running the x2goclient!
This was a surprise.
Thanks,
Jon

Due to reasons too sad to describe, I need to X2go from a modern
Fedora 40 system to a Ubuntu 10.04 (!) system.
Running ssh from the command line fails with the message
Unable to negotiate with XX.XX.XX.XX port 22: no matching host key
type found. Their offer: ssh-rsa,ssh-dss
After some work I got this to work by adding
-oHostKeyAlgorithms=+ssh-rsa -oPubkeyAcceptedAlgorithms=+ssh-rsa
to the ssh command line.
My question is how can I add these options to the ssh command that
X2go executes on the client?
Cordially, Jon Forrest
