Description of problem:

On Fedora Workstation and SilverBlue 35, a Remmina client cannot connect to X2goServer as the utility x2goversion is outputting incomplete data.

Version-Release number of selected component (if applicable):
Fedora Workstation and SilverBlue 35
x2goserver: 4.1.0.3

How reproducible:

Steps to Reproduce:
1.Using Fedora Workstation 35, install x2goserver and associated packages
Ensure that SSHD is working. 

Using Remmina, with the X2go plugin, which you can install using the Snap version, attempt to make a connection and you'll be met with a dialog stating that pyhoca-cli has stopped unexpectedly.

(Note: That with X2go's own Client, a connection is made satisfactorily, but with SELINUX AVC errors!)

2.You can also reproduce with pyhoca-cli as well.
Install this on your Fedora Workstation 35 and issue a request to localhost.
pyhoca-cli -d --libdebug -u john --password secret --list-desktops --server 127.0.0.1
The output incorrectly states the server is not installed.


Actual results:
pyhoca-cli[2660] (x2gocontrolsession-pylib) DEBUG: server-side X2Go components and their versions are: {'': '4.1.0.3'}
pyhoca-cli: error: the remote server does not have the X2Go Server software installed

Additional info:

/usr/bin/x2goversion
The cause is LINE 45
X2GO_COMPONENT="$(echo "$(basename ${compfile})" | cut -d '.' -f '2')"
For Fedora 35, this should be
X2GO_COMPONENT="$(echo "$(basename ${compfile})" | cut -d '.' -f '4')"

On Fedora you can make a quick edit.
But I'm defeated on Silverblue!
Fortunately Xrdp works!


I'll be amazed if this ever gets fixed.
X2go having not issued any Fedora versions since 30, and the fix is needed in Fedora not Ubuntu.
OR, I'll cross post to Remmina to see if they can work round this issue in their client code.
