If Yosemite is already working on other updates or various ongoing processes, it may produce error messages instead of completing El Capitan. Remember that for a new download, especially a large one, Mac OS X needs to shut down various programs and processes.

If you really want to like El Capitan but can’t actually complete the download due to error messages, your current version of Yosemite is probably causing trouble.
