For the record, automatic updates on Ubuntu/Debian managed installations can be re-enabled by setting the following property back to true:

/etc/wordpress/config-localhost.php

#This will disable the update notification.
define('WP_CORE_UPDATE', false);

Doing so may not be a good idea; for example I don’t know what happens when the package in the Debian repository is updated to a version that’s older than the one you upgraded to, and you then run an apt-get upgrade…

Does anyone know where WordPress stores the location where it checks for updates? And what’s the “official” location?

After moving to a host with Apache 2.0, all is fine…

Just moved WordPress into the root directory, and the problem persists, so it isn’t related to the /blog/ in the path…
