Symptoms

Parallels Plesk Panel (PP) 11.0.9 cannot be installed to a Parallels Virtuozzo Containers (PVC) container based on the centos-6-x86_64 OS template with autoinstaller because yum is not installed. The following error is shown:

ERROR: The Yum utility is not installed in your system.
Not all packages were installed.
Please resolve this issue and try installing the packages again.
If you cannot resolve the issue on your own, contact product technical support for assistance.

Cause

Parallels does not provide third-party components (Apache, Perl, etc.) or updates to system packages for CentOS 6, and instead relies on packages provided by the OS vendor. To be able to install Parallels Plesk Panel on CentOS 6, the Yum package manager should be installed and configured. Otherwise, the following error message will be displayed by Parallels Installer on an attempt to install PP:

ERROR: The Yum utility is not installed in your system.

EZ templates pp10 and pp11 for CentOS 6 install Yum by dependencies so that Parallels Installer works properly:


However, if the initial Parallels Plesk Panel installation inside a container is done not through EZ templates, but by downloading Parallels Installer from the website, then the Yum package manager should be installed and configured manually.

Resolution

Install the Yum package to the container. To do this, run the following command on the Hardware Node:


(replacing CTID with the ID of the PVC container where you installed PP 11.0.9.)
