‚ÄčI've never tried to connect through a proxy with update_amber, so I have
no way of knowing. This is the first time I've seen a reported problem,
but that doesn't mean that the proxy support works (I had no way of testing
it, so I just did what I thought would work).

Just to be clear:

$AMBERHOME/update_amber --proxy=$http_proxy

just stores the proxy information so update_amber knows how to connect to
the internet. You still need to run $AMBERHOME/update_amber --upgrade in
order to download the upgrade. If that doesn't work, you can always
download the AmberTools 15 tarball directly.

On a related note, how were you able to download the updates to AmberTools
