How to fix yum install error on centos | Cannot find a valid baseurl for repo: base/7/x86_64
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

: w q !
to save the file and close file editor.
