Title:
  can python-crypto and pycryptodome co-exist?

Status in pycryptodome package in Ubuntu:
  Invalid
Status in python-crypto package in Ubuntu:
  Invalid

Bug description:
  Hello,

  The pycryptodome docs have:

  > The installation procedure depends on the package you want the library in.
  > PyCryptodome can be used as:
  >$
  > #. **a drop-in replacement for the old PyCrypto library**.
  >    You install it with::
  >$
  >        pip install pycryptodome
  > $$$
  >    In this case, all modules are installed under the ``Crypto`` package.
  > $$$$
  >    One must avoid having both PyCrypto and PyCryptodome installed
  >    at the same time, as they will interfere with each other.
  >$
  >    This option is therefore recommended only when you are sure that
  >    the whole application is deployed in a ``virtualenv``.
  >$
  > #. **a library independent of the old PyCrypto**.
  >    You install it with::

  >        pip install pycryptodomex

  >    PyCrypto and PyCryptodome can coexist.

  Currently there's no Breaks or Conflicts lines in either package:

  $ grep -e Break -e Conflict pycryptodome/bionic/pycryptodome-3.4.7/debian/* python-crypto/bionic/python-crypto-2.6.1/debian/*
  grep: pycryptodome/bionic/pycryptodome-3.4.7/debian/patches: Is a directory
  grep: pycryptodome/bionic/pycryptodome-3.4.7/debian/source: Is a directory
  grep: pycryptodome/bionic/pycryptodome-3.4.7/debian/tests: Is a directory
  grep: pycryptodome/bionic/pycryptodome-3.4.7/debian/upstream: Is a directory
  python-crypto/bionic/python-crypto-2.6.1/debian/changelog:    - Remove obsolete Breaks+Replaces
  python-crypto/bionic/python-crypto-2.6.1/debian/changelog:  * Drop obsolete Conflicts/Replaces with python2.3-crypto and
  python-crypto/bionic/python-crypto-2.6.1/debian/changelog:    - Add Breaks python{,3}-keyring (<= 0.7.1-1) to python{,3}-crypto.
  grep: python-crypto/bionic/python-crypto-2.6.1/debian/patches: Is a directory
  grep: python-crypto/bionic/python-crypto-2.6.1/debian/source: Is a directory
  grep: python-crypto/bionic/python-crypto-2.6.1/debian/tests: Is a directory

  
  Can these two packages be installed side-by-side? Or is this something 
  that matters only to 'pip' installs?

  Thanks
