The running kernel version ($running_version) does not match that of
the default boot entry ($boot_version). This could be due to the kernel
being changed by an update, meaning that a reboot should resolve this.
However, this also could indicate that the system does not have control
over which kernel and early boot environment (initrd) is used upon
reboot, which is required to upgrade the operating system with this
script.
If this message remains after a reboot, your server may have been
configured to boot into a particular kernel directly rather than to an
instance of the GRUB2 boot loader. This often happens to virtualized
servers, but physical servers also can have this problem under certain
configurations. Your provider may have a solution to allow booting into
GRUB2; contact them for further information.
