OK! We can’t see the stack there, but I’m guessing it’s the same as this topic. The mate-power-manager package is bad news. It just doesn’t work for multi user systems. (It won’t let users see the power buttons on that machine). We don’t have it on our systems, and indeed when I build a MATE singularity image for desktops I don’t include it. So I would get rid of it. Again, users shouldn’t need to see that panel anyhow - it’s the button to stop/restart, so it’s useless to them anyhow.
The very last line of your output is exactly the same as the other topic. For whatever reason the stderr of your job isn’t combined with the stdout. What kind of scheduler do you have? I want to be sure there’s not something amiss on our side.
