Fortunately it is harmless, only leads to a connection delay in rare situations (e.g. when a user connects for the first time). Nevertheless, we'll make a new attempt to fix this.

Qluman GUI 13.4.7 / 13.5.1 / 13.5.2 connection issues

Hi all, When I try to connect to our head node using qluman I'm getting the following error while using using "ssh -X root@servername qluman-qt" to connect: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-13/qluman-qt.py", line 74, in <module> main() File "/usr/lib/python3/dist-packages/qluman-13/qluman-qt.py", line 70, in main w = MainWindow.make(background=not args.nobackground, app=app) File "/usr/lib/python3/dist-packages/qluman-13/client/qt/MainWindow.py", line 204, in make w.conf(cluster_model=model, background=background, app=app) File "/usr/lib/python3/dist-packages/qluman-13/client/qt/MainWindow.py", line 213, in conf self.restoreState() File "/usr/lib/python3/dist-packages/qluman-13/client/qt/MainWindow.py", line 320, in restoreState state = QtCore.Qt.WindowState(int(state)) TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType' Also tried to connect using apptainer with qluman-13.5.2-singularity.sqsh (or qluman-13.4.7-singularity.sqsh) and receive something similar: QStandardPaths: error creating runtime directory '/run/user/1000' (Read-only file system) QStandardPaths: error creating runtime directory '/run/user/1000' (Read-only file system) Qt: Session management error: None of the authentication protocols specified are supported Traceback (most recent call last): File "/usr/lib/python3/dist-packages/qluman-13/qluman-qt.py", line 74, in <module> main() File "/usr/lib/python3/dist-packages/qluman-13/qluman-qt.py", line 70, in main w = MainWindow.make(background=not args.nobackground, app=app) File "/usr/lib/python3/dist-packages/qluman-13/client/qt/MainWindow.py", line 204, in make w.conf(cluster_model=model, background=background, app=app) File "/usr/lib/python3/dist-packages/qluman-13/client/qt/MainWindow.py", line 213, in conf self.restoreState() File "/usr/lib/python3/dist-packages/qluman-13/client/qt/MainWindow.py", line 320, in restoreState state = QtCore.Qt.WindowState(int(state)) TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType' Qlustar server version is 13.5.1 (fresh install of last month). We also have an old headnode running qluman 13.2.1. I am able to connect to the new head node after connecting to the qluman server of our old headnode (running qluman server 13.2.1) using "ssh -X root@OLDservername qluman-qt" and connecting the new headnode using the Qluman GUI. While this is a nice workaround, I would like to decommission the old headnode in the near future. Am I doing something wrong while trying to connect directly to our new head node using either ssh -X or apptainer? Head node is fully up to date, ran "apt- update" & "apt dist-upgrade" Thanks, Wouter
