Thanks Bastian - I'm hugely appreciating your help!!

There are still 9 tests failing - have a look at the autopkgtest
results on salsa (currently available at
https://salsa.debian.org/science-team/spyder/-/jobs/9535670/raw)

At least it's not hanging any longer!  I'm not sure when I'll have
time to dig into these myself.

Best wishes,

   Julian
