Comment (by dd32):

 > If zlib.output_compression is "on" in server (my vps server), then auto-
 update works, but without verbose output or any indication that install
 has succeeded.

 You should still see all the messages, and that it's completed.

 zlib at the PHP, or server level, has the disadvantage that it creates an
 output buffer, and waits for the entire page to be generated before it can
 send it to the client, as a result, The page is never delivered to the
 browser until WordPress has finished the updates. You should however, see
 the page once it finishes generating.. Are you seeing something different?

 This is something that could be documented on the codex, but there isn't
 really much more that can be said or done, different server configurations
 will affect different applications differently - Most users will not even
 know what zlib is..
