How to fix yum update error: "Error: requested datatype primary not available"

Question

I'm running a CentOS 7 web server which uses remi repository for updating php version to 7.3.

When I try to update the system using yum:

yum update

I get the following error message: Error: requested datatype primary not available

What I tried:

I googled it and found this solution and I found that the problem was the remi repository so I ran

yum clean all --verbose

then

yum --disablerepo="remi*" update

and I could update the system, all but php 7.3!

Additional info:

The content of the repo file located in /etc/yum.repos.d/remi-php73.repo is:

# This repository only provides PHP 7.3 and its extensions
# NOTICE: common dependencies are in "remi-safe"

which I get installing using the guide on Remi's website

yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

Answer 1

I finally found the solution.

I edited the file vim /etc/yum.repos.d/remi-php73.repo and changed the commented lines marked with ->

[remi-php73]
name=Remi's PHP 7.3 RPM repository for Enterprise Linux 7 - $basearch
#baseurl=http://rpms.remirepo.net/enterprise/7/php73/$basearch/
-> mirrorlist=https://rpms.remirepo.net/enterprise/7/php73/httpsmirror
-> #mirrorlist=http://cdn.remirepo.net/enterprise/7/php73/mirror
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

It looks like there's some problem with the repo URLs.
