Generally, we come across this error when we try to interact with yum, use EasyApache or run updates.

As part of our Server Management Services, we assist our customers with several CloudLinux queries.

Today, let us see how we can resolve this error.

Error – Cannot find a valid baseurl for repo: base

Recently, our customers informed us that they came across the below error while trying to interact with yum, use EasyApache, or run updates:

This can be due to two major reasons:

1. The base, epel, extras, and updates repositories come default on CentOS 6 systems. However, we don’t use it on CloudLinux systems. Accidentally reactivation can cause issues.
2. The error indicates, YUM is incapable of accessing the base repository that it uses to find package information.

In most cases, there are two possible causes of the error:

• Network issues
• Base URL being commented out in the repository configuration file.

Fix the error

1. We disable these repositories to ensure that the system continues to function properly:

# yum-config-manager –disable base
# yum-config-manager –disable epel
# yum-config-manager –disable extras
# yum-config-manager –disable updates

2. a. Firstly, we ensure the system is connected to the Internet.

For example, google.com.

# ping google.com

The ping result will indicate either a DNS problem or no Internet connectivity.

Here, we edit network interface configuration files. We can find the network interface, via the IP command.

To edit the configuration for interface enp0s8, open the file /etc/sysconfig/network-scripts/ifcfg-enp0s8.

# vi /etc/sysconfig/network-scripts/ifcfg-enp0s8

If it is a DNS problem, we add the Nameservers in the configuration file.

DNS1=10.0.2.2
DNS2=8.8.8.8

Then we restart the Network Manager service with the systemctl command.

# systemctl restart NetworkManager

Once done, we run a ping once more.

# ping google.com

Eventually, run the yum update or any yum command that gave us the above error.

b. Suppose, the connection and DNS are working fine. Then the issue will be with the repo configuration file /etc/yum.repos.d/CentOS-Base.repo.

Firstly, we open the file using any command-line editor.

# vi /etc/yum.repos.d/CentOS-Base.repo

In the [base] section, we uncomment the baseurl by removing the leading # on the baseurl line.

Then we save the changes and close the file.

Finally, we run the yum command again.

# yum update
