I copied the package folder (ProPac, http://www.pages.drexel.edu/~hgk22/software/ProPac/ProPac.html) in
$UserBaseDirectory/Applications in Linux mint.
But when I called it by
the ouput is
Get::noopen: Cannot open ProPac`. >> $Failed
I tried install it from File menu but appears the same error.
But in Windows OS I have no problem with installation of this package and using it.
