Re: python3-mastodon fails CI due to bad magic?

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?

Seems that reprotest on salsa, is not installing the python3-magic.

I don't think that can be a problem with cpython.

I'm not sure what you found out so far. When I grepped the log you
linked, I couldn't find python3-magic or libmagic. I believe the
packages isn't installed and the test therefore fails.
I'm guessing now, but I think this has to do with reproducible build in salsa.
