WordPress 2.7.1 update and the old WordPress Automatic Update plugin
WordPress 2.7 included a new automatic update feature — tools -> upgrade — that replaces the functionality that was previously only available from a plugin. Unfortunately, the new feature is completely incompatible with the plugin.
If you’re trying to auto-upgrade your plugin and you get a hang at “Unpacking the core update”, then you need to deactivate AND delete the old “WordPress Automatic Upgrade” plugin (most recent version: 1.2.2) before you can successfully use the new upgrade function in WordPress.

Thanks, this has been discussed in a more detailed manner here:

Even with that (non buggy, perfectly functional) plugin removed, many people are still getting hung at “Unpacking the core update”. Removing the update plugin only got us past the download problem. Even deactivating all plugins doesn’t get past the unpacking.
Agreed with Exceptjoe: I had to not just deactivate, but delete entirely the plugin on all three of my WordPress installs.
Deleting it didn’t work for me, and there’s no .maint file. Still looking for an “automatic” solution. Shame the perfectly good plugin god ruined
In fact, I’ve now deleted ALL plugins, and it still won’t update
Hmn. It worked for me after I deleted it. Check that either your webserver user is the owner AND group or that you have permissions set to 777 on your entire directory… and that zip utilities are installed on the server. I wish that WordPress had included more debug functions to tell us what was wrong…
Thank you. It was OK for me just deactivating the plugin.
Congrats
Nope, this didn’t work for me. Why did the WP people have to mess up such a good thing?
Deactivating all plugins on my site worked for me. Even I had not the update plugin installed…
