deluge depends on py-openssl, which since 0.14, uses py-cryptography

Having said that, it looks like your Python installation doesnt have
md5, which will be the root-cause of the issue above.

You'll want to isolate why that is the case.

It's strange, hashlib is standard module, and md5 needs to be imported
like that:

from hashlib import md5 (see [1])

It's perhaps problem from deluge?

Nah, it is using hashlib.md5() as grep suggests. And the whole thing is 
in ./deluge/ui/web/auth.py - md5() method is only used for 
authentication in web ui.
