[CentOS] x2go is not able to start x2go sessions

Hi everyone.

Since a few days I can't connect with a server via x2go. I get the 
following error message:

Connection failed. Failed to start X2Go Agent session with ID 
stefsimo-60-1560249248_stDMATE_dp24. X2Go Agent terminated unexpectedly. 
Aborting session startup.

Did you get the same error?

cat /etc/centos-release CentOS Linux release 7.6.1810 (Core)

cat /proc/version Linux version 3.10.0-957.5.1.el7.x86_64 
(mockbuild at kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red 
Hat 4.8.5-36) (GCC) ) #1 SMP Fri Feb 1 14:54:57 UTC 2019

Best regards

Stefano
