Upgrade from Mountain Lion to El Captain Failed

I am running Mountain Lion on Mac mini late 2012. I loaded El Captain from Apple Store and start the upgrade procedure. After a while the system rebooted and got a OS installation screen. After a while I got the message "OS X could not be installed on your computer no packages were eligible for install" with a restart button, pressing "Restart" the computer Restarted came age to the OS instillation screen and after few minutes - same message again. The only option was to restart with "Command R" and to reinstall Mountain Lion.

Mac mini, OS X 10.11

Did you download El Capitan from here, How to upgrade to OS X El Capitan – Apple Support.

The error 'no packages were eligible for install' usually means that the certificates for El Capitan

have expired. In October last year this was the case for a few of the macOS's available for download including

El Capitan. Apple updated the certificate for El Capitan and have introduced a new method for creating the

Install OS X El Capitan.app.

From the link above you download Install MacOSX.dmg, on opening that you will see Install MacOSX.pkg,

double-clicking on that will open an installation dialogue, this will then convert InstallMacOSX.pkg

to the Install OS X El Capitan.app which will be in your Applications folder.

Is that the method you used, if not how and where did you get your El Capitan installer from,

the more details the better.
