Installing El Capiton on an old Mac Book Pro today, I received the error:

I'm unable to complete the installation of El Capitan. I only have the HD & RAM memory installed (no battery). Other Mac OS-X Versions are installing OK (even Windows). But, when I try to upgrade to El Capitan it never finishes the update. Also, it will not install via USB thumb drive. I have tried everything! Install El Capitan. OK, now you can click that Continue button in the installer window. (If the installer isn’t running, go to your Applications folder and double click the Install OS X El.

No packages were eligible for install. Contact the software manufacturer for assistance.

Quit the installer to restart your computer and try again.

I checked Apple’s support Matrix (it is a very old macbook pro) at https://support.apple.com/kb/SP728?locale=en_GB and it was listed as supported.

After lots of Googling and investigation, I discovered that the date and time were not set to current, the macbook thought it was year 2000.
