Error details

Same as my previous bug report on this (which was automatically closed), but to confirm I've run this 5 times and the same output each time (the advice on the previous bug report was the run it a second time). Again to note, other people seem to have reported this same issue.

Hello @murray ,

My apologies for the late response. This issue appears to have been introduced recently, as MoveIt 2 now assumes by default that the display is set to :0, which is not the case for the course machines.

We are currently working on updating the course material to reflect this change and provide a workaround. In any case, this is not the launch file you will ultimately use. If you continue through the notebook, you will find an updated version that does not have this issue, so you should be able to proceed with the course without any problems.

Best,

Hi @murray,

This error is now fixed.

Thank you very much for reporting the issue.

Context:

1. The problem was that MoveIt had the DISPLAY variable hardcoded to display :0, but in The Construct we use the displays :1 and :2 instead. That is why it failed.
2. We fixed by making DISPLAY=:0 point to DISPLAY=:1 by default.

If you find any other issues while using the platform, feel free to report.
