[X2Go-User] How to Pass SSH Options From X2goclient?

[Jon Forrest]

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,
