[X2Go-Dev] Bug#1470: x2goserver: Broken x2goversion results in failed connection

[Randy Goldenberg]

Package: x2goserver
Version: 4.1.0.3-0~1708~ubuntu16.04.1

Attempts to connect to x2goserver fail, with error message "the remote server 
does not have the X2Go Server software installed". Transcript is provided 
below.  Issue appears to be caused by what is likely a typo in x2goversion.  
Patch attached.
