I'm sure I'm missing something simple, however, I'm having issues with SSH in
Guacamole. We build in a separate build environment, package into an RPM,
then install into a Docker container and deploy to another environment. SSH
was previously working, but after a fresh rebuild of everything, it seems to
be having issues now. I'm struggling to figure out where to look next.
Perhaps there are permissions issues or RPM packaging issues that might be
biting me?
I'm receiving the error message:
guacd[2135]: WARNING: Support for protocol "ssh" is not installed
I am compiling guacamole-server from source on RHEL-7.5, and receive the
following output during configure:
