Holoviz Tutorial Installation: "anaconda-project run jupyter notebook" step fails on Linux + Win 10


Guessing its a anaconda-project problem

Linux 5.15.0-43-generic: python 3.10.4 , anaconda-project 0.11.0
Windows 10 Pro, 21H2: python 3.10.4, anaconda-project 0.11.0

Followed directions at: https://holoviz.org/tutorial/Setup.html

All successful until i get to following step on Linux-

$anaconda-project run jupyter notebook

keep getting error below, (keep in mind packages being reported as "missing" are verified to exist and have same version used "conda list" to verify, and conda env is activated)-

Collecting package metadata (current_repodata.json): ...working... done
Solving environment: ...working... failed with repodata from current_repodata.json, will retry with next repodata source.
