Problem Description
When installing software on CentOS 8.2 today, March 7, 2022, the following error was reported:
CentOS Linux 8 - AppStream Error: Failed to download metadata for repository 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist
A search on the Internet failed to solve it, and finally found the answer in the Alibaba Cloud developer community! URL: https://developer.aliyun.com/mirror/centos
Cause of the problem
CentOS Linux 8 will come to the end of life cycle (End of Life, EoL) on December 31, 2022. That is, the CentOS Linux 8 operating system version has ended its life cycle (EOL), and the Linux community no longer maintains this operating system version. So the original CentOS Linux 8 yum source is also invalid! eventually lead to this problem.
Solution to the problem
Replace the yum source of CentOS Linux 8
1. Switch to the source directory and back up the original source
[root@VM-16-7-centos ~]# yum module list nodejs
Repository AppStream is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository epel is listed more than once in the configuration
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/nodesource-el8.repo; 配置：ID 为 "failovermethod" 的 OptionBinding 不存在
Invalid configuration value: failovermethod=priority in /etc/yum.repos.d/nodesource-el8.repo; 配置：ID 为 "failovermethod" 的 OptionBinding 不存在
