zoom 6.0+ fails to install -- invalid path for downloaded package about homebrew-cask

[nobeh]

The debug outputs are attached above, but the summary is that it seems that download location assumed for the Zoom package has changed:

The zoom Casks were updated in #174335 and #174336, both of which passed our CI tests.

Also, zoom upgraded as normal on two of my personal machines (one Intel, one Arm), so this issue cannot be reproduced and therefore must be something with your particular set-up.

Sorry we cannot be of more help.
