• issues with python-datasketch - use of async keyword? seems to be in experimental_aio sub directory https://github.com/ekzhu/datasketch/blob/master/setup.py#L88

Unpacking python-cffi (1.11.5-1ppa1~xenial) ...
dpkg: error processing archive /var/cache/apt/archives/python-cffi_1.11.5-1ppa1~xenial_amd64.deb (--unpack):
 trying to overwrite '/usr/lib/python2.7/dist-packages/_cffi_backend.x86_64-linux-gnu.so', which is also in package python-cffi-backend 1.5.2-1ubuntu1

Also name conflict with https://launchpad.net/ubuntu/+source/cffi/

[joachimmetz]

Removed cffi. Various errors surface during the tests:
https://travis-ci.org/google/timesketch/jobs/491037813

TypeError: set_cookie() got an unexpected keyword argument 'samesite'

Updated python-jwt and python-werkzeug, looks like that addressed the issue

[joachimmetz]

TypeError: from_buffer() cannot return the address of the raw string within a str or unicode or bytearray object

Possibly cffi related

https://launchpad.net/ubuntu/+source/python-cffi/

[joachimmetz]

Switched to Bionic

The following packages have unmet dependencies:
 python3-cryptography : Depends: python3-enum34 but it is not installable

To do remove python3-enum34 as a dependency

same for python3-configparser

[joachimmetz]

Made changes to cryptography, now having conflicts with nose

https://nose.readthedocs.io/en/latest/#python3
Warning nose itself supports python 3, but many 3rd-party plugins do not!

Hmmm
