Step 4: Clean up yum package manager
yum packager manager store the local listings and metadata of previous installed packages. It is necessary to run the clean up once to remove all those past cached data.
sudo yum clean all
[root@localhost ~]# sudo yum clean all Loaded plugins: fastestmirror Cleaning repos: base extras updates Cleaning up list of fastest mirrors
Step 5: Reboot the Server after Clean Up
To clean up the local cache and repository you need to reboot the server once. It will also speed up the process and will avoid any unnecessary issues.
reboot
Use the below command to reboot the Server:
#reboot
Step 6: Upgrade the CentOS to latest release
sudo yum upgrade
