Greetings

We have now a warning running bitbake:

$ bitbake core-image-minimal
/usr/lib/python3/dist-packages/html5lib/_trie/_base.py:3: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working
  from collections import Mapping

Loaded 1469 entries from dependency cache.
NOTE: Resolving any missing task queue dependencies

A few updates to the Python code seem to be needed.

A host / distro specific warning so medium not from bitbake we believe.
Can this be suppressed on only offending hosts?

Can we avoid this warning somehow? Why are we using html5lib ?

May be due to an out of date version of 'beautiful soup', try updating?
Comment 2 Tim Orling 2021-10-07 15:08:46 UTC 
Since it is dist-packages, that tells me this is a Debian/Ubuntu host.
Comment 3 Randy MacLeod 2021-10-07 16:58:45 UTC 
Add Grace and Sandy since I think there's a WR bug for this as well that one of you folks own.

We use bs4 included in bitbake) which seems to import html5lib from the host's python and the issue is in the host's html5lib. This seems to occur on ubuntu 20.04 LTS, at least for me.

Closing the bug as I no longer have it in Ubuntu 22.04.
