Using kcarectl free patch on CentOS 7.8 Kcarectl binaries were updated overnight. Now I am receiving an email every 4 hours from Cron:

/usr/bin/kcarectl -- auto-update
"Updates are already downloaded
No updates needed for this kernel"

How can I suppress these emails?

Hello Nigel,
Thank you for reaching out! To fix this issue, please reinstall KernelCare by using the following steps:

rm -f /etc/cron.d/kcare-cron
yum reinstall -y kernelcare

If you have the servers with KernelCare version older than 2.27-1, then please use there:

rm -f /etc/cron.d/kcare-cron
yum update -y kernelcare

It should fix the issue. Let me know if you have any questions. Hope to hear from you soon.
