Guacamole logs “Wrong number of arguments”

I've built and installed Guacamole 1.0.0 and Tomcat 8. Make and install
went fine so far. Tomcat and Guacamole are running. However I fail to
connect (tried SSH and RDP).

Syslog says:

Apr 13 21:05:17 myserver guacd[28616]: Creating new client for protocol
"ssh"

For the completeness sake my configure-output before make && make install:

------------------------------------------------
guacamole-server version 1.0.0

    Library status:

      freerdp ............. yes

       guacd ...... yes
       guacenc .... yes
       guaclog .... yes

    Init scripts: no
    Systemd units: /etc/systemd/system

I'm running 32-bit Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-88-generic
i686). I tried the latest Guacamole 1.1.0 first having the same error.

Both server and client have the same version:
pom.xml in guacamole.war says: <version>1.0.0</version>
guacd -v says: Guacamole proxy daemon (guacd) version 1.0.0

Unfortunately Google didn't help very much with the error message "Wrong
number of arguments". Any help is very appreciated!

I've created a StackExchange question for this issue:
https://askubuntu.com/questions/1226827/guacamole-logs-wrong-number-of-arguments

Thanks, Klaus

Hi Mike,

I was eager to say "nothing special" but remembered to have been tried
to apt-get install guacamole before what didn't seem to fully work.
I purged it but that purge didn't remove everything. Another apt
autoremove removed several packages including:

libguac-client-rdp0:i386 (0.9.9-2build1) ...
libguac-client-ssh0:i386 (0.9.9-2build1) ...
libguac-client-vnc0:i386 (0.9.9-2build1) ...
libguac11:i386 (0.9.9-2build1) ...

I assume these led to a version conflict bringing this error.

Now I can work further!  :-)

Thanks a lot!

Has anything else been done on the server except for installing
dependencies and building the source? What specifically has been installed?

Any chance your source install is mixed with packages of the same from your
distribution?

Klaus,

All my installations are 64-bit Ubuntu 18.04, I've just tried the SSH 
option (not something I normally use) and it's working fine.

That in itself may not be useful to you, other than to know that it 
should work, but from this I wonder what options you're including in 
your connection setup?

In mine, since I was connecting to a machine on the same subnet, all I 
entered (using the GUI) was the connection name, ip address and port 
numbner for the connection - it wasn't necessary to add anything else. 
The error message from guacd you're logging suggests to me that perhaps 
you could be passing something that's not needed?
