I saw that too, and yet the logs have:
 import magic
  File "/usr/lib/python3/dist-packages/magic/__init__.py", line 361, in
<module>

That's a python3-magic file, so it exists.

However, a bit of googling showed up this [1] where due to the fact that
python3-magic uses ctype.util.find.library if the environment is "strange"
(e.g. in a snap) the load fails.
Possibly the reprotest environment qualifies as "strange" and the load line
is failing in an odd way?

   return ctypes.cdll.LoadLibrary(find_library('magic'))

Anyone else use python3-magic and reprotest? Does it work and why?
