Due to pyhoca-cly bug, actually already fixed upstream, resume of X2GO session is impossible in Remmina.

Reproducible: Always

Steps to Reproduce:
1.Start an X2GO session with remmina
2.Close the session window
3.Try to resume de session
Actual Results:  
Session resume fails and the trace logs shows:

pyhoca-cli[162387] (PyHocaCLI) NOTICE: give the X2Go session some time to come up...
Traceback (most recent call last):
  File "/usr/bin/pyhoca-cli", line 455, in <module>
    thisPyHocaCLI.MainLoop()
  File "/usr/lib/python3.11/site-packages/pyhoca/cli/frontend.py", line 702, in MainLoop
    self.resume_session(self.x2go_session_hash)
  File "/usr/lib/python3.11/site-packages/pyhoca/cli/frontend.py", line 229, in resume_session
    if available_sessions is None:
       ^^^^^^^^^^^^^^^^^^
UnboundLocalError: cannot access local variable 'available_sessions' where it is not associated with a value


Expected Results:  
Normal resume of the session.

versions:
* pyhoca-cli-0.6.1.2-11.fc38
* remmina-plugins-x2go-1.4.30-1.fc38
* remmina-1.4.30-1.fc38

upstream actually fixed this BUG by commit:
2020-03-11 	pyhoca/cli/frontend.py: Fix reference before assignment...
[https://code.x2go.org/pyhoca-cli?p=pyhoca-cli.git;a=commit;h=2b507520a7b4984d7020a6d5153d29350a24a9a9]

Unfortunately, this did not result in an actual hotfix release.

However (IMHO), to improve user experience with remmina, which is an awesome RDP software, it would be desirable to 'patch' the pyhoca-cli package and use, the git repo on a more recent commit than the obsolete packaged 0.6.1.2 version.

Additionally, the remmina plugin seems to use features more recent that this previsouly mentionned commit.

As the following traces show:

This feature seems finalized upstream by commit [https://code.x2go.org/pyhoca-cli?p=pyhoca-cli.git;a=commit;h=22b8402428a5b7e13eb5094e1961b07907c38520]
