The upgrade to Ubuntu Lucid Lynx 10.04 took a while but was without major incident. Still, a few things to fix:
1. Login Window: sudo -u gdm gconftool-2 –set –type boolean /apps/gdm/simple-greeter/disable_user_list true
2. Mediawiki – Blank pages. From MediaWiki: "A blank white page indicates a PHP error which isn't being printed to the screen. To [reveal] this, add the following lines to the LocalSettings.php file, underneath the <?php:"
error_reporting( E_ALL );
ini_set( 'display_errors', 1 );
Here's the error:
Parse error: syntax error, unexpected T_NAMESPACE, expecting T_STRING in /var/www/mediawiki/includes/Namespace.php on line 46
Evidently there is an incompatibility with PHP 5.3.1 and Mediawiki 1.15.1. Found a solution here.
Note this "fix" could backfire in the future with an update; I've got backup.
3. Opera, Squeezebox and Virtual box repositories were disabled on upgrade (but not Google's Chrome repo!). I'll have to re-enable them in Software Sources.
