ImportError: cannot import name 'filefind' from 'traitlets.utils' (/usr/lib/python3/dist-packages/traitlets/utils/init.py)

Hi,

I'm trying to add an env with:
`python -m ipykernel install --name=py38 --prefix=/home/user/`

And I get the following error:
`ImportError: cannot import name 'filefind' from 'traitlets.utils' (/usr/lib/python3/dist-packages/traitlets/utils/init.py)`
After the call of ipykernel/kernelapp.py line 33

With ipykernel 6.0 and 6.7 it works, but not with version 6.8
Multiple people are facing this issue:

Cheers

Start with ipykernel/kernelapp.py line 33 and the reported traitlets.utils/init.py path, then reproduce the command with ipykernel 6.8 and compare it with 6.0 or 6.7. Determine the compatibility issue behind the filefind import; done means the same install command succeeds on 6.8.
