Troubleshooting

Further debugging in the SP ULS logs and we found some strange facts which are based on event receivers- please refer below

SPSolutionExporter: Microsoft.SharePoint.SPException: Feature definition with Id 77658379-50ff-4e1e-a431-5652bee07a87 failed validation
Looking for ‘ReceiverAssembly’ attribute in manifest root node for solution
Looking for ‘ReceiverClass’ attribute in manifest root node for solution
The ‘Format’ attribute is invalid – The value ‘CheckBoxes’ is invalid according to its datatype

I debug further to find out where the problem. I downloaded the saved wsp’s from /_catalogs/solutions/Forms/AllItems.aspx to my desktop. Renamed it to .cab. Extracted all the contents and found some interesting facts along with manifest.xml file like List Instances, Modules, Property bags, web template. Inside List Instances, I found ElementsFields.xml Once I opened the above xml file, search for the check boxes and found the following

save as template

Further exploration on this, it seems that the checkbox attribute is invalid and needs to be modified.

Resolution

Remove that affected column / remove the affected content type – does not require IISRESET also.
