As announced by CentOS.org the CentOS Linux 8 has reached End Of Life (EOL) on December 31st, 2021.
This means that CentOS 8 will not receive any updates, either nomal bug fixes or fixes for security vulnerabilities.
Instructions to convert from the CentOS Linux 8 distribution to CentOS Stream 8 are published at https://www.centos.org/centos-stream/ and are also below for your convenience.
[root@centos ~]# dnf swap centos-linux-repos centos-stream-repos [root@centos ~]# dnf distro-sync
This will result in some package updates and new packages being installed, which is expected.
