This is a known Sugar crm problem. First you should check your permissions on the upload folder. The problem ist that the upload was not correct and you have now a incomplete package uploaded where some files are missing.

Here is a good post how to fix that problem.
Try uncompressing and then compressing the module, before upload. That works for this headache.
A reason for this error could also be that you are archiving the Module including the containing folder. You should only archive the files inside the Module folder

Example using "zip" on linux:
zip ModuleName.zip manifest.php files
