 mathgl is failing with new python defaults in proposed, because the test is falling back to all-proposed
 I think we need to construct a trigger that has all the Qt packages that the test wants to install, so it doesn't fail to install the deps at first due to the Qt ABI change
 and so does not run with the python defaults in proposed
 test submitted. not sure I got everything, but it should run quickly to find out
 the konclude timeout looks nastier
 mathgl passed 🎉
 looks like another migration reference of konclude is on it's way to timing out this thime
 if so, that should be the qtbase tests ok
 so just a few other tests against other sources to sort. which I have retried
 plus qgis of course
 if qgis becomes a final blocked, perhaps archive admin could restore the previous version in proposed long enough to get a migration
