Pushing a signed nuget package to GitHub package repository

[bstordrup]

As part of development, my organization has received a NuGet package that is signed from the author. We now try to push this package to GitHub Package repository, and that succeeds, but when pulling the package again, there is an error that the package has been changed since it was signed.

Error (active)	NU3008	Package 'XXXXXXXXXX 9.6.0' from source 'https://nuget.pkg.github.com/YYYYYY/index.json': The package integrity check failed. The package has changed since it was signed. Try clearing the local http-cache and run nuget operation again.

I cleared the %UserProfile%.nuget\packages entry for the package, and it did not resolve it. It did not even create the entry for the package again.
