Old thread - I know
Jul 01, 2011 This file is a Windows-based package manager for Cygwin. By default, it will download and install the latest minimal install of Cygwin, but on future launches, it will also enable you to add new packages and update your existing Cygwin software. So after you install Cygwin do not delete or lose the location of setup.exe! How to install Perl modules via ActivePerl ActivePerl comes with a Perl Package Manager (PPM) utility which allows you to easily install additional Perl modules. Instructions for how to install Perl modules via PPM may be found in our How to Install & Configure ActivePerl on Windows guide.
But I came across it because I had the very same problem after upgrading my cygwin.
As here is no clear statement if and how it was solved, I thought I'd better tell what I did to solve my issue:
I simply reinstalled all of those incomplete packages.
I think they came in because there were some problems during installation with incomplete downloads and processes which couldn't be stopped. But they seemed to be gone when I choose 'retry'.
Apparently this was not the case and even when I tried to reinstall the incomplete packages, I again received the 'incomplete downloads' message. This time when retrying, I choose another mirror host and finally it worked.
