STEPS TO REPRODUCE
installed centos with minimal configuration. used artikle http://kb.parallels.com/article_17_819_en.html to create the disks. then i used the document plesk-10-installation-upgrade-guide.pdf to install plesk. first i created .autoinstallerrc and added the line USE_YUM='yes' to it as descibed in the manual on page 11(Centos only)
then i used One-Click installer procedure to install plesk panel as descibed on page 17.
my host is behind a NAT. the installer begins installing/downloading some components. then after few minutes it fails. see any additional information for the log. how can i fix this?
