Hi !

You are my hero.... i remember that on this machine i made some tryouts at the beginning and compiled without a prefix....

So (shame on me) there were a very old version of all lib in /usr/local/lib... (new setup used to be compiled with prefix /usr

So clenaed up and.. all fine :) Thanks a lot

Ciao Gerd

    Hi,

    Are you using Ubuntu packages or building guacamole-server /
    guacd yourself?  You can see there's a segfault in the guacd ssh
    library. That's either a bug or some problem in the way it was
    compiled...  If your two machines are the same, check for any
    differences in your guacamole-server ./configure output.  And
    make sure guacd is looking for its libraries in the right place
    (I had to set LD_LIBRARY_PATH to the /usr/local/guacamole
    directory I installed it in).

    cheers,

        Hi !

        I have 2 servers (both Ubuntu 20.04 on a x64 machine)

        bothe are setup as the same (1 with GUI and 1 without)

        on Machine w/o GUI  ia had to switch back to 1.2.0 because it
        had
        problems with ssh (reported here)

        No i tried with 1.4.0 but its still the same

        this happen only on one machine... relevant packages are the

I would say make sure that you do not have any previous versions of the libguac-client-ssh.so.0.0.0 file on the system running guacd. Maybe clean it completely of all previous guacd components/files, and then do a clean build/install.

If you're still getting this, it would be useful to have the full stack trace from the segfault - you'd need to run gdb with the core file and the debug symbols (or source directory) to get this.
