Thank you both!  I should've done a more digging into the commit history for
the related HTTP fixes.  I'm not sure I would've easily figured out the apt
method issue but it's a relief to see there's a command-line flag for that.

I'll try this again from master soon and glad to help with any other debug
(although as evidenced I'm a bit slow to figure out the various best practices
for testing all this).
