ResolutionAs Plesk PowerPack contains additional Plesk components, PleskPP template must be installed after Plesk template or on the VE which already has Plesk installed.
So it should not be installed at the same time with Plesk template using VZMC, HSPComplete or command line simultaneously, as current Virtuozzo version does not allow to specify the order in which packages are installed. Virtuozzo starts installing them randomly and in case Plesk PP is installed first, installation will fail.
The correct way is to install Plesk template first. When Plesk template is installed successfully it is safe to install Plesk PowerPack template.
