[X2Go-Dev] Bug#1478: pyhoca-cli failing to resume an existing session

[Chris Greenshields]

Package: pyhoca-cli
Version: 0.6.1.2

With x2goserver 4.1.0.0-3, pyhoca-cli fails to resume an existing session.

For example with:
pyhoca-cli --username <user> --server <ip> -R <session ID>

Error message is:

pyhoca-cli[1269418] NOTICE: preparing requested X2Go session
pyhoca-cli[1269418] (PyHocaCLI) NOTICE: preparing requested X2Go session

An upgrade to x2goserver 4.1.0.3 does not fix the problem, since pyhoca-cli 0.6.1.2 fails with
"pyhoca-cli: error: the remote server does not have the X2Go Server software installed"
