SugarCRM

Steps to reproduce:

In SugarCRM instance, navigate to Admin > Module Loader
Click the file selector input and choose the Kayko_for_SugarCRM.zip package
Click Upload button

Resulting Error:
ZIP Error(0): Status(0): Arhive( upload://Kayko_for_SugarCRM.zip):
Directory(/path/to/sugarcrm/cache/upgrades/temp/wm8KVP)

Cause of Error:
The zip file contains a directory:

/Kayko_for_SugarCRM

and inside of that directory are the package files, such as manifest.php . Sugar expects all files to be in root of package, not inside a container directory. So the root of the zip should be:

/LICENSE.txt
/manifest.php
/icons/
/scripts/
/SugarModules/

instead of

/Kayko_for_SugarCRM/LICENSE.txt
/Kayko_for_SugarCRM/manifest.php
/Kayko_for_SugarCRM/icons/
/Kayko_for_SugarCRM/scripts/
/Kayko_for_SugarCRM/SugarModules/

Also, the package still contains the project directories and files, such as:

__MACOSX/Kayko_for_SugarCRM/SugarModules/modules/ky_Tickets/.idea/

Generally any unneeded files should not be packaged, and in some web stacks, hidden system files like .DS_Store and __MACOSX will cause installation and unpacking errors. With all of these extra files removed, the package is half the size and uploads without error in moments.
