The update works just fine and doesn't have any problems.
As already explained, so many times, each time there's an update (when some user always mistakenly assume the update has "problems"), it takes some time to both upload files *and* for the new files to propagate to the network of 170 Cloudflare servers around the world.
Which means, if you run the Live Update while the upload and replication is not yet complete, it's likely you'll have issues.
The solution, as explained so many times, is just wait a bit, and try the Live Update again later, until you'll see no files are still downloaded.
