Hi Wouter,

we could identify the cause of the issue. A new version of the GUI will be available shortly.

Best,

Roland

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:

Also tried to connect using apptainer with qluman-13.5.2-singularity.sqsh (or qluman-13.4.7-singularity.sqsh) and receive something similar:

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
