Could this binary package be copied to Xenial(16.04)? Manual download/install of the deb from https://launchpad.net/ubuntu/yakkety/amd64/python3-bs4/4.5.1-1 fixes the issue. Thanks!

This issue is breaking variety in Xenial (https://bugs.launchpad.net/variety/+bug/1645572), so I'm seconding the request to fix it there as well.

By using remarkable (a markdown editor) I ran into the same error.
I suggest to use the following version of html5lib exactly

sudo pip install html5lib==0.9999999

with seven 9s exactly.

Hi Folks,

If we are going to SRU a fix back to an existing release we are going to need to have a test case/steps-to-reproduce. Can someone give us a python code snippet we could use to test this out? It would help get the ball rolling.

Thanks!

I realize this bug doesn't impact any version of html5lib officially in xenial. However, for whatever reason if a user decides to install a newer version of html5lib (e.g. via pip), bs4 will break as a side effect and possibly render other programs unusable.

AFAIK it's 'pip install html5lib' (to get html5lib >= 0.99999999) and then trying to import bs4 by any means that triggers the issue.

Hi,

Is there any particular reason this was unmarked from Xenial? Although I don't believe mixing Python library versions is an optimal configuration, this bug truly does break setups.
