Power Panel -> Software Packages menu, the list of the suggested packages to be installed is too broad and suggests too many versions, which mostly cannot be installed with the following error:
Operation with the Container "example.tst" is finished with errors: Can not install packages: ' vzpkg install -q -p 101 plesk-billing' exec failed - Error: Package is not found Error: /usr/share/vzyum/bin/yum failed, exitcode=1
The issue is recognized as a PVA bug with internal ID PVA-33221.
The list is combined from all the packages, available on the hardware node, while it should be filtered by the templates, installed in the container.
The fix will be included in one of future PVA updates.
