There is a minor WordPress update today, version 2.7.1. Since v2.7, they have introduced an automatic update feature that is part of the core WP. It will detect and compare your current installed version against the latest available in WordPress repository.
If you have v2.7, you should see the following once you login as admin.
Clicking on the “Please update now” link should bring you to the upgrade page:
As a precautionary move, I first check that I have the latest backup including DB and I hit “Upgrade Automatically”. Normally it should update say upgrade successfully but instead I encountered this error:
Downloading update from http://wordpress.org/wordpress-2.7.1.zip
Unpacking the core update
Fatal error: Cannot redeclare pclziputilpathreduction() (previously declared in /home/myhome/public_html/wp-content/plugins/wordpress-automatic-upgrade/lib/pclzip.lib.php:5421) in /home/myhome/public_html/wp-admin/includes/class-pclzip.php on line 5498
I tried it on my other WP sites and encountered the same issue. I guess it has something to do with plugins as most issues encountered on WP are related to plugins. I went to the plugin page and inspected each and every plugin I have installed. And there you go, It may be conflicting with WPAU or WordPress Automatic Upgrade plugin by Keith Dsouza.
This plugin has the functionality as the name says to upgrade WordPress automatically. You just follow a series of questions and you will end with an upgraded version. This plugin has done its job perfectly prior to v2.7 version.
I deactivated WPAU and tried the upgrade again using the functionality provided by WP core. This time, it went without a hitch:
This just means the function provided by WPAU is so important that it got incorporated in the WP core. I very much agree. I guess I can say that WPAU can retire now and thank you very much.
I was having the same problem. Thank you for confirming my suspicions.

Dude,thanks a lot man. I was looking for the cause of this problem but bah your solution did work. I didnt know that the plugin itself was the cause of the problem itself !

Thank you SO MUCH!!!! I really appreciate it

I didn’t know that WP has its own auto-update function now. I got the same error and found your post. WPAU was an invaluable plugin and I’m happy it’s function is integrated WP core at last.

Thanks by the explanation. I didn’t know that WP incorporated this fuction, but that is logical.
I updated my version of WP. Thank you so much

Even deleting said plugin many people still can’t get past the “unpacking the core update” step. Webpage goes straight to done. File is downloaded and complete, archive tests ok. Even then manually deactivating every other plugin results in the same fail with no error message.

In fact, I’ve now deleted ALL plugins, and it still won’t update. just gets to “Unpacking the core update” and stops

Thank you, I did as you suggested and it worked perfectly.

Thank you so much for this. I had a website that had excellent rankings and then one day took a dive. I realized that I didn’t do an update for so long that it automatically reset my All in One SEO plugin, which is the reason why my website took a dump. I went to update and was getting the same error you mentioned. Once I got rid of the WP Auto Update plugin it updated without any error.
I am grateful that your issue was fixed by this little tip. Thanks for dropping by….
good site! thanks!http://www.listasegmentada.com
I have something new for you to look at. You’ll see an exceptionally powerful automation suite that gets both traffic and links from 7 distinct sources and A huge number of different sites at the push of a few buttons. Just take a look at this software in action… http://tinyurl.com/7cgd3le
