Try:
– switching to the Twenty Eleven theme by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.
– resetting the plugins folder by FTP or phpMyAdmin.
– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.
– running the upgrade manually using wp-admin/upgrade.php
-re-uploading all the files except the wp-content folder from a fresh download worked like a charm.
Thanks a ton.
Excellent! 🙂
FWIW, the odd back download does happen some time. Especially when thousands of other users are downloading the upgrade at the same time.
I encountered the same issue. Do I do each recommendation above step-by-step or just try one solution at-a-time?

Those solutions don’t overlap so you can try one at a time or do all three. Then run the upgrade manually using wp-admin/upgrade.php.
Edit: Also note, this thread was marked resolved; I looked at it by mistake. 😉 Resolved threads indicates there’s no more problem for the OP.
Going forward please create your own.
I just removed the db.php file (database cache) from the plugins folder, and that solved the problem.
Just wanted to add that the exact same thing happened to me. I followed Jazoja’s advice (after manually uploading the 3.4 files except wp-content) and it worked. However, db.php is located in the wp-content folder, not the plugins folder.

Tried these, and I’m still having problems. I’ve never had this upgrade problem before. Actually 2 other sites updated just fine, and they’re on the same server! Any other thoughts?
I’m having the same issues as well despite a fresh manual install, all plugins disabled, and running the upgrade manually through the yourdomain.com/wp-admin/upgrade.php suggestions
How I fixed my site was by increasing the PHP memory limit. I added this to the top of my wp-config.php just after the beginning <?php:
define('WP_MEMORY_LIMIT', '64M');
If that doesn’t work, try increasing the limit to ‘128M’.
Just for another possible solution.
This has happened twice on my site (on a shared server with shared database servers), and somehow one or more database tables became corrupt. It was obvious when I set DEBUG to TRUE and tried to log in (lots of errors about a corrupt user table).
Running a MySQL repair on the database resolved it for me.
