[CentOS7] Memo for when yum install gives [Errno 14] HTTP Error 404 - Not Found

Hello everyone.
forever Hello World
This is Kawai from the System Solutions Department,

The other day, when I tried to install a package on an AWS EC2 instance (graviton), for some reason

[Errno 14] HTTP Error 404 - Not Found

I got stuck because of this error, so I'm writing this article as a memo.
To summarize the result, it seems the cause was the lack of mirroring sites for the AArch64 (ARM64) CPU architecture.
I hope this will be helpful to anyone who encounters a similar error in the same environment.

Operating environment and error details

Operating environment

cat /etc/proc/version Linux version 4.14.256-197.484.amzn2.aarch64 (xxxx@ip-xx-xx-xx-xx) (gcc version 7.3.1 20180712 (Red Hat 7.3.1-13) (GCC))

zabbix-agentError when installing

yum install zabbix-agent http://repo.zabbix.com/zabbix/5.0/rhel/7/aarch64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. http://repo.zabbix.com/non-supported/rhel/7/aarch64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found Trying other mirror.

As you can see, the mirror site URL also results in a 404 error, and the installation cannot proceed

What I tried

1. Clear cache

yum clean all

2. Update the zabbix-agent package

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm

The above two points did not solve the problem

This solves it

I later found out that for CentOS 7, there seem to be few mirror sites that provide support for architectures other than x86_64. To enable ARM64 support, Iinstalled the EPEL repository,which successfully resolved the issue (the zabbix-agent version ended up being 4, but that was within expectations).
