Interesting David, Those lines are only in the jqt version of the lab. I wonder if it is a result of the duplicated lab in the labs list. We haven't seen that in other platforms as the duplication seems to run the JHS version from either of the duplicated links.
Part of the challenge is that I am using the new platform to write my labs and it looks like excludes has not been implemented to remove labs that cannot run in JHS. Since this looks like a jqt version running in JHS, I would wait to get the excluded labs thing cleaned up before we determine that the Ubuntu platform is the problem. Thank you so much for the testing. I am only on Mac, so your wider view is very much appreciated.
