went just fine except apache2/php4/mysql had some problems and the blog stopped working.
The problem was WordPress 1.5 couldn't connect to mysql, but phpmyadmin could connect just fine. Strange. This is what I ended up doing:
$ sudo apt-get --purge remove apache2 phpmyadmin php4 (and maybe a few others that depended on apache or php)
... verify that /etc/apache2/, /etc/php4 were gone...
$ sudo apt-get install apache2 php4 phpmyadmin
At appears that one of the configuration files for either php4 or apache2 didn't get properly upgraded.
