El Capitan No Packages Were Eligible For Install Big Sur

Scenario

Requirements

1. You have a 'OS X El Capitan.dmg' downloaded. (look for them in torrent.)
   
2. You have a USB drive (USB flash drive) of at least 8 GB of capacity.
   
3. All this process will happen in a OS X environment. (No Windows please.)

Happy path

El Capitan No Packages Were Eligible For Install On Imac

1. Create an install boot drive using the USB drive and the 'OS X El Capitan.dmg'.
   
2. Boot to recovery mode in the USB drive and wipe the hard drive (ALL DATA IN HARD DRIVE WILL BE LOST, DO BACKUP!!!)
   
3. Install 'OS X El Capitan' and have a beer!

Step 1

1. Double click on 'OS X El Capitan.dmg' to mount this in 'Finder'. Once mount and open, it should show a name like this 'OS X El Capitan'. Copy this to your 'Documents' folder (Command + C and Command + V, or simply grab the icon and drop it in the 'Documents').
   
2. Insert the USB drive to your computer and rename it like 'INSTALL'.
   
3. Open the terminal and do this command:
   
   
   sudo Documents/OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/INSTALL --applicationpath Documents/OS X El Capitan.app
   
4. This command will ask you for your password in order to proceed. It will ask you to confirm with 'Y' for the actions that will happen in the USB drive. Once it start it should take from 15 to 30 minutes or until it finishes coping all installation files to the USB drive and making it able to boot.

Step 2

1. Restart your computer and once you hear the sound that is starting press and keep press for a while 'Option (Alt)' key until it shows a menu for select different drives. Select the one that says something like 'OS X 10.11 install drive', and click in the below arrow.
   
2. Wait until it boots up a screen of different options. Now click on the top bar on the screen that says 'Utilities', and then 'Disk Utility...'. Once open this menu, select the first 'Internal' drive (at the left), and then click on 'Erase' and on the confirmation dialog enter in the highlighted input name 'Macintosh' and then click 'Erase'. Wait until it finish doing this process. Now go to the top bar in the screen and click on 'Disk Utility' and the 'Quit Disk Utility'.
   
3. Now it should take you to the same screen when it boot up.

Step 3

1. We are ready to install but this step is the most critical one because of different errors that can happen so lets do it in way that whatever error happen we can keep trying to install.
   
2. Click on the top bar on the screen that says 'Utilities', and then 'Terminal ...'. Once the terminal is open do this command:
   installer -verbose -pkg /Volumes/Mac OS X Install DVD/Packages/OSInstall.mpkg -target /Volumes/Macintosh
   
3. The installation happens in text mode, so be patient until it finishes. At this time 2 types of error might happen:
   A. 'This copy of the Install OS X El Capitan application can't be verified. It may have been corrupted or tampered with during downloading.'
   B. 'OS X could not be installed on your computer. No package were eligible for install. Contact the software manufacturer for assistance. Quit the installer to restart your computer and try again. Restart'
   Both errors have the same solution and is very easy (and very crazy). So whenever one of this errors happens the installation stops. So we need to change the date of the computer to a year when 'OS X El Capitan' were released (don't ask me why), just type something like this:
   date 101407002015
   or date 101407002016
   after that type command
   date
   to check that the date is in 2015 or in the second case 2016.
   and then try again the installer command in step 2 in the terminal (installer -verbose etc...) and wait until the installation finishes (if the hard drive is not a SSD it will take some time, just wait until no more ### symbols).
   
4. Now click on the top bar on the screen on the apple symbol and restart the computer. Once you hear the sound that is starting DISCONNECT THE USB DRIVE and have your beer in your hand to configure your fresh Mac or iMac.

If you ever get this error while attempting to install OS X, you will likely need to set the date using terminal.
The simplest way to set it (if you have no OS installed on the machine) is to boot the install media, open the terminal and check the date (type date).
The following information was found on someones site (sorry I forget which), but I have included it here to make it easier to correct this issue.
Use the following command in terminal to set the machine to a time and date of your choosing:
date {month}{day}{hour}{minute}{year}
For example, to set it to 8pm on the 2nd October 2018

date 100220002018
The command below will output the current date in a format suitable for use on another machine:
date '+%m%d%H%M%Y.%S'
Further, the following (mouthful of a command) will let you specify a date and time in a more readable format and set it in one go:
date -f '%Y-%m-%d %H:%M:%S' '2016-07-09 15:20:10'
