ImportError: 'No module named argparse' on KernelCare servers

During KernelCare update or licensing the server you may face the following issue:

# kcarectl --update
Traceback (most recent call last):
File "/usr/bin/kcarectl", line 38, in <module>
from argparse import ArgumentParser, SUPPRESS
ImportError: No module named argparse

or/and

# kcarectl --register yourLicenseKey
Traceback (most recent call last):
File "/usr/bin/kcarectl", line 38, in <module>
from argparse import ArgumentParser, SUPPRESS
ImportError: No module named argparse

This issue happens if the python-argparse package is missing on your server. It's enough to install this package to fix that:

yum install python-argparse
