In my case none of the instructions were a perfect solution. If you were as unlucky as me, try this detailed one

1. Put all your executing code in a separate text file with an arbitrary name such as foo.sh and save it in an arbitrary place.
2. Add
   

   #!/bin/sh

   as first line of your code.
3. Try executing your foo.sh by
   

   sudo foo.sh

   to check there are no errors at all.
4. Provide your /etc/rc.local script with full path and name of your created script after the sh command
   

   sh '/path/to/your/script/foo.sh'

5. Remember to put the above line before the last line of code
   

   exit 0

   at the end of the /etc/rc.local script.
6. Check first line of /etc/rc.local to be
   

   #!/bin/sh -e

7. Make your /etc/rc.local executable in case it is not already executable by
   

   sudo chown root /etc/rc.local
   sudo chmod 755 /etc/rc.local

8. Check everything works fine by executing
   

   sudo /etc/init.d/rc.local start

9. Test restart your system.

On newer Ubuntu versions systemd is used and /etc/rc.local is not loaded always by default.
Check if the Compatibility service is loaded with

systemctl status rc-local.service
