​Did you modify any of the source code within Amber itself? Perhaps
something I suggested for (I can't remember if that was your
thread originally or not). If so, the upgrade won't work on your tree.

You could always unpack a fresh copy of AmberTools 14 if you have a copy on
your computer and --upgrade that (that way you could download a 25 MB
upgrade instead of the 220 MB full distribution).

​No, this is not necessary. In fact, you should be able to simply unpack
AmberTools15.tar.bz2 on top of your existing amber14 directory if you have
Amber 14 installed (i.e., pmemd). If you don't have Amber 14 installed
(just AmberTools 14), you might as well either unpack AmberTools15.tar.bz2
into a separate directory or delete your existing amber14/ first.
