This is a known issue, related to libssh2.
have a look at this ticket https://issues.apache.org/jira/browse/GUACAMOLE-1619
and this PR https://github.com/libssh2/libssh2/pull/626#event-5853667761
It has been merged in the master branch of libssh2 end of last year, but
depending on your OS, the available package may not have been build after those
changes (for example Ubuntu Jammy libssh2-1-dev has been released in March
2022, and for Debian Bullseye, it was released in Dec 2020), so you may have to
build it yourself.

Hello everyone,
We see that with guacamole version 1.4.0, SSH to an Ubuntu 22.04 machine fails
and the following log is seen in guacd logs.
ERROR: SSH handshake failed.
It looks to be an issue related to supported HostKeyAlgorithms on the SSH
server side. Is there a plan to support newer HostKey algorithms (e.g. EC
based) in guacd?
Is there a workaround/solution that can be used without enabling RSA, DSA on
the Ubuntu SSH server?
Regards,Pramod
