I noticed the latest Ubuntu 8.04 Apache2 packages have not been updated in the Virtualmin repository. Here is the forum post I submitted about it: https://www.virtualmin.com/node/17328. The latest Ubuntu 8.04 version of Apache2 is 2.2.8-1ubuntu0.19 (based on http://packages.ubuntu.com/hardy/apache2). If you could get that updated, I would appreciate it, as it's holding up PCI compliance.
If I can do anything to help, let me know.
