> libssh2 has recently grown support for elliptic curve cryptography, including
> support for elliptic curve KEX algorithms. The current guacd Docker image
> doesn't inherit this support, however, because it uses Debian Buster as its
> base image. To have access to a newer libssh2, the guacd image will need to
> use at least Debian Bullseye.
> It may be worth updating the image to simply point at Debian stable, assuming
> there is no longer any issue with the FreeRDP version included by that
> version of Debian. Meanwhile, the Jenkins build that performs nightly
> rebuilds of the established Docker images for the previous release can simply
> be updated to point to Debian Bullseye with its build args and thus magically
> become up-to-date.
