I admit, a few months ago I tried using Atomic Turtle's PHP 5 upgrade pacakges without any luck... (I have lost several customers without PHP 5 support, but that is another story.) Anyway, I am now having problems trying to upgrade to Plesk 8.0.1 (from 8.0.0 on Fedora Core 2). I get the following error, any suggestions on how to fix? Download file versions.inf3: 13%..100% done Download file PSA_8.0.1/plesk-8.0.1-fc2-i386.inf3: 100% done Checking for system installed packages...done.
