  Hello there,

  Following some removal from Python itself, the following started to
  appear in autopkgtest:

  2993s --- <exception caught here> ---
  2993s   File "/usr/lib/python3/dist-packages/twisted/internet/defer.py", line 1999, in _inlineCallbacks
  2993s     result = context.run(
  2993s   File "/usr/lib/python3/dist-packages/twisted/python/failure.py", line 519, in throwExceptionIntoGenerator
  2993s     return g.throw(self.value.with_traceback(self.tb))
  2993s   File "/usr/lib/python3/dist-packages/twisted/web/_flatten.py", line 435, in _flattenTree
  2993s     roots.append(frame.f_locals["root"])
  2993s builtins.KeyError: 'root'

  This is fixed upstream in
  https://github.com/twisted/twisted/pull/12213

  I've cherry-picked the needed changes in a patch. I'll send a debdiff
  with everything shortly.
