RESOLUTION
Full Plesk package could consist of three different templates.- Plesk template
- Plesk PowerPack template
- Plesk Language Pack template
It’s important to understand that Plesk PowerPack template is set of additional applications which work with core Plesk only, i.e. they cannot be installed and used separately. So it’s impossible to install Plesk PowerPack before Plesk itself. Language pack should be installed after Plesk core as well.
In case of using VZMC or HSPComplete for templates installation it’s possible to choose several templates to be installed on issued VE at once.
NOTE: In this case all chosen templates are installed in random order and it’s possible that PowerPack or Language pack is tried to be installed before Plesk. This leads to template installation failure.
To avoid such behavior it’s necessary to install Plesk core template at the first as separate template installation. Then you can install Plesk PowerPack and Plesk language pack choosing them within one installation as they don’t depend on each other.
