If you have no access to an Ethernet connection, you could try upgrading while in Safe Mode to make sure nothing installed is interfering with the download.

Using Wi-Fi to download upgrade files will often corrupt those files and they will fail to install as they should. The reason is that Wi-Fi is often too slow for these very large files. Instead, use a wired Ethernet connection if possible and it should work just fine. Otherwise, you may have to do several Wi-Fi downloads to get a clean one that works.
