A quick test says otherwise for debian-12 (bookworm). Note that I had to
install the 'wheel' python module to quiet down some whining when
installing pysftp in the next step. That happens occasionally with some
packages.
Just documenting it here to capture it for future google group searches
folks might do when trying to do similar things....
