I don’t know about the rest of you, but I’ve experienced many instances where the Auto-update feature in WordPress fails to update either a plugin or WordPress itself.
The solution to this problem is remarkably simple, and hopefully will be fixed soon by the WP core developers in an upcoming release. The problem seems to be caused by a messy previous upgrade in which files are left in a temporary “upgrade” directory with the wp-content directory.
In order to solve the problem, you simply need to delete the “upgrade” directory in it’s entirety and then try the upgrade again. I’ve yet to find an instance on several blogs across multiple machines where this didn’t solve the problem.
Thanks for this!
Thank you SO much! This post has cured my many hours of frustration after a failed upgrade to 3.6!
You saved me from a reinstall. Thanks a million.
Thank you.
Thank you so much. you saved my blog :)

Thank you! I finally managed to fix it.
I have all the permissions set to 777 but still it does not work for me
Same here, and I had a good laugh at this ‘solution’.
I have tried to delete the upgrade file but it refuses to delete, also i found some files in the upgrade directory which also refused to delete. How can i change the permissions for this folder so as to be able to delete it
Thank you SO much! Worked like a charm. Was struggling for so long trying to figure out what the problem was. A Google search turned up a lot of the same solutions that didn’t work for me. Thanks for a new one :)
Doesn’t work for me.
Hi,
Thanks it works for me!
It doesn’t work. I have tried every fix I can to get auto upgrade to work .. could it be because I am going from 2.84 to 3.42? I am a Drupal whiz, but very novice at WP and while I wanted to keep it that way, this client insisted on a WP blog so I stumble through whatever I have to .. it’s not very intuitive.
Does this auto upgrade EVER work? Or do I have to figure out the manual thing .. dreading …
I have tried about 10 times .. it always hangs on Unpacking the Download and going via FTP, I can see where much of it downloaded but apparently not all of it.. I have disabled the plugins .. checked the permissions .. everything I can think of to get it to work and it just doesn’t.
Other ideas?
Thanks,
Nancy
I tried deleting the “Upgrade” folder, but that didn’t work.
What did work was going into my CPanel for the website and doing the upgrade with Fantastico. The WordPress was originally installed through that, and it had been years since an update had been done (not my department! LOL).
Even though Fantastico was one or two upgrades behind, once it had done it’s upgrade thing, the WordPress updates could be done on their own, on the program, the themes, and the plugins.
All is well now, thanks for the great ideas everyone.
Thank you! Thank you! Thank you! I thought our site was toast when this happened, what an easy fix!
