Question Selinux shows warnings in centOS

[Azurel]

System: CentOS Linux 7.6.1810 (Core)‬ with Plesk Onyx Version 17.8.11

with yum update I get this warnings

ValueError: SELinux policy is not managed or store cannot be accessed.
warning: %postun(bind-32:9.9.4-72.el7.x86_64) scriptlet failed, exit status 1
Non-fatal POSTUN scriptlet failure in rpm package 32:bind-9.9.4-72.el7.x86_64

OSError: No such file or directory
ValueError: SELinux policy is not managed or store cannot be accessed.
warning: %posttrans(bind-32:9.9.4-73.el7_6.x86_64) scriptlet failed, exit status 1
Non-fatal POSTTRANS scriptlet failure in rpm package 32:bind-9.9.4-73.el7_6.x86_64

So I take a look in selinux config "/etc/selinux/config" its disabled by default

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

# rpm -qa | grep selinux
selinux-policy-devel-3.13.1-229.el7_6.9.noarch
selinux-policy-targeted-3.13.1-229.el7_6.9.noarch
libselinux-python-2.5-14.1.el7.x86_64
selinux-policy-3.13.1-229.el7_6.9.noarch
libselinux-2.5-14.1.el7.x86_64
libselinux-utils-2.5-14.1.el7.x86_64
psa-selinux-17.8.11-cos7.build1708181031.14.noarch

What can I do to fix the yum warnings?

Are you running it as root?

Just for reference in case anyone else comes across this post looking for an answer...

I also got this error running a YUM update:

"
OSError: No such file or directory
ValueError: SELinux policy is not managed or store cannot be accessed.
warning: %posttrans(bind-32:9.9.4-73.el7_6.x86_64) scriptlet failed, exit status 1
Non-fatal POSTTRANS scriptlet failure in rpm package 32:bind-9.9.4-73.el7_6.x86_64
"

Bind did work without issue after the update.

Googling suggests this is a bug with SELinux and occurs if SELinux is installed but not enabled - related links:

Warnings after CentOS upgrade

General advice seems to be the error can be safely ignored if your not using SELinux, 48 hours on from the update - I have not seen any issues on a busy server with 300+ web hosting / email accounts.
