If you are currently using CentOS 8, you will have to find an alternative operating system. This is because its end-of-life cycle has been cut short in December 2021. But if you use CentOS 7, you do not have to take any action right now. This is because CentOS 7 will reach its End-of-Life on June 30th, 2024.
Stupid me installed CentOS 8 in December 2020 instead of 7 without reading the news about this.
