Re: Unexpected network read error when accessing https on Ubuntu 16.04.

  One more point here.
The error I am experienced is not an unexpected network read error.
Instead, in Lynx editions, not  2.8.9dev.16, I get an error decompressing 
temporary file error.
I cannot duplicate Luke's problem, not when say following google searches 
using lynx 2.8.9dev16 which was our edition of lynx prior to a recent 
change.
