<PRE>This is beyond the scope of pycrypto for the moment - you have system
problems because you've upgraded pip yourself.
This looks familiar because I did the same exact thing myself in the
process of testing this (and it didn't go smoothly - same problem you're
having - so I rolled that back to get pip2 and pip3 working properly).
Let's get you back on track.
# At this point let's get back to the system default pips and go from
there. IF you upgraded the system pip to 9.0.1 as it appears, here's how
to fix them:
sudo dnf reinstall python-pip python3-pip
# Now, with that done, run these:
sudo pip3.5 uninstall pycrypto
sudo pip2.7 uninstall pycrypto
# Once that's done, list them as per my earlier email:
pip3.5 list | grep pycrypt
pip2.7 list | grep pycrypt
Shouldn't see `pycrypto` there now. If you do... you installed it some
other way (perhaps as a dnf package?) Uninstall it via the same mechanism
you installed it and try again.
Now go through the steps in my previous email to install pycryptodome and
pycryptodomex for the purpose of this test, and report the results.
