Today I was deploying Windows Server 2016 Nano. After the deployment I wanted to install the IIS packages but I ran into the following error-message: The module ‘NanoServerPackage’ cannot be installed because the catalog signature in ‘NanoServerPackage.cat’ does not match the hash generated from the module. From PowerShell: Find-PackageProvider NanoServerPackage | Install-PackageProvider -force Install-PackageProvider : The module ‘NanoServerPackage’ cannot be installed because the catalog signature in ‘NanoServerPackage.cat’ does not match the hash generated from the module.
