NOTE:  To keep a record of the installation process, we recommend you enable logging before starting.  This will greatly help if for some reason you need to review or submit logs for troubleshooting later.  You can do this via one of two ways: 

1. Terminal Logging:  Exact steps depend on the terminal client you are using but there should be settings in your terminal's console to configure this (usually several thousand lines of scrollback is sufficient).  OR if you don't want to use that or it has terrible logging facilities you can generate a replay-able log file with timings by using
2. script:  To use, simply run:  script, then do the steps you wish to record, then end it by hitting ^D (CTRL-D) or type exit to stop recording.  You can then rename the file called typescript from the location where script was invoked and review/share that if necessary (for more information see man script).
    WARNING, be aware that using any interactive tool that allows arbitrary cursor placement, ex: vi or vim , etc. will cause corruption in the log so you may wish to stop logging (temporarily) if you need to use one, and use script -a to resume appending after completing usage of the interactive tool.
