Upgrade Os X Lion To Mojave

An installation error occurs sometimes for when upgrading from OS X Snow Leopard to OS X Lion “Can’t download the additional components needed to install Mac OS X” – Check your network configuration as the install needs to pull down software over the internet.

But the network configuration is OK.!

Check that Software Update can connect directly to Apple Software Update Servers not a custom internal one, remove any Managed Preferences if it is a managed host.
