1. Update YUM

Updating YUM itself might solve some compatibility issues:

yum update

yum install wget 

2. Check Network Connectivity

Ensure the server has internet access, as YUM needs to download packages from repositories online. Test with:

ping google.com

If there’s no response, troubleshoot the network connection first.

3. Verify Repository Configuration

Check that your repository configuration files are correctly set up in /etc/yum.repos.d/ Sometimes, repositories may be disabled or misconfigured. Ensure all necessary repositories are enabled.

4. Install CentOS Base and Updates Repositories (Default Repos)

CentOS comes with default repositories configured in /etc/yum.repos.d/CentOS-Base.repo. This file contains sections for:

• base: The main OS packages.
• updates: Updates to the packages.
• extras: Additional packages that complement the base OS.
• centosplus: Extended packages not included in the base.

Make sure this file exists and has the necessary sections. You can edit it using a text editor like nano or vi:

vi CentOS-Base

    [base]
    name=CentOS-$releasever - Base
    baseurl=https://vault.centos.org/7.9.2009/os/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    enabled=1

    [updates]
    name=CentOS-$releasever - Updates
    baseurl=https://vault.centos.org/7.9.2009/updates/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    enabled=1

    [extras]
    name=CentOS-$releasever - Extras
    baseurl=https://vault.centos.org/7.9.2009/extras/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    enabled=1

    [centosplus]
    name=CentOS-$releasever - Plus
    baseurl=https://vault.centos.org/7.9.2009/centosplus/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    enabled=0
