Can't get pyethapp to build on Ubuntu Zesty

[karalabe]

If I install pyethapp via pip, starting it fails with

AttributeError: /lib/x86_64-linux-gnu/libcrypto.so.1.0.0: undefined symbol: EVP_CIPHER_CTX_reset

If I clone and build the repo, starting it fails with

ImportError: cannot import name keccak

There's probably multiple reasons why

ImportError: cannot import name keccak

can come up, but if you install the most recent pysha3 it has keccak and does not fail with this whereas the previous pysha3 available in debian/ubuntu did. ie this is fixed in artful/bionic, but the package name of pysha3 changed so keep that in mind.

Well, even if it would build, it will probably not run... so... you know...

Works for me:

sudo apt-get remove python-crypto
sudo pip install --upgrade pycryptodome
