ELevate Blocker: The grub2-pc package is not installed.

Symptoms

You receive an error similar to the following when running the ELevate script.

CONFIG_TEXT: [WARN] *** Elevation Blocker detected: ***
 The grub2-pc package is not installed. The GRUB2 boot loader is
 required to upgrade via leapp.

Cause

Warning: The system must be able to control the boot process by changing the GRUB2 configuration. If GRUB2 is not installed, your system administrator must install and configure it before attempting to run the ELevate script.

When the ELevate script detects that the grub2-pc package is not installed, it reports that it is not installed.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.

2. Install the grub2-pc package.

   # yum install grub2-pc

Note: Even on servers using a UEFI bootloader, this is a safe package to install on the server.
