Fixing the "Failed Loading Plugin 'spacewalk'" Error on YUM/DNF
If you're managing a server and encounter the error:
Failed loading plugin "spacewalk": No module named 'up2date_client.up2dateAuth'
This guide will help you resolve it. The error usually occurs when the spacewalk plugin is installed but misconfigured or not required, leaving residual files that cause YUM/DNF to fail.
This blog explains the root cause, step-by-step fixes, and how to safely remove unnecessary plugins.
What Causes This Error?
The spacewalk plugin is part of the Spacewalk and Red Hat Satellite system management tools. If you are not actively using Spacewalk or its related services, the error occurs because:
- Residual or outdated plugin configurations remain on your system.
- The spacewalk plugin is partially installed but missing required dependencies.
- YUM or DNF attempts to load the plugin, but it fails due to the above issues.
While this does not directly harm your system, it can block updates and package installations.
Step-by-Step Fix
Step 1: Clean Package Manager Cache
Stale cache files in YUM/DNF may cause errors. Start by clearing all cached metadata:
yum clean all
or
dnf clean all
These commands remove old metadata and force the package manager to fetch updated data from repositories.
Step 2: Identify Installed Plugins
List all installed YUM or DNF plugins and check for the presence of the spacewalk plugin:
yum list installed | grep plugin
or
dnf list installed | grep plugin
Look for entries like dnf-plugin-spacewalk or python3-dnf-plugin-spacewalk.
Step 3: Remove Spacewalk-Related Plugins
If you find any plugins related to spacewalk, remove them. For example:
yum remove python3-dnf-plugin-spacewalk dnf-plugin-spacewalk
You can substitute yum with dnf if you’re using the DNF package manager.
Step 4: Clean Cache Again
After removing the plugin, clean the cache again to ensure no remnants remain:
yum clean all
or
dnf clean all
Step 5: Test the Fix
Run a basic YUM/DNF operation to verify that the error is resolved:
yum update
If the process completes without the spacewalk error, the issue is resolved.
Example Commands That Worked
Here’s the exact sequence of commands used to resolve the issue:
# Clean package manager cache
yum clean all
dnf clean all
# List installed plugins
yum list installed | grep plugin
dnf list installed | grep plugin
# Remove spacewalk-related plugins (if found)
yum remove python3-dnf-plugin-spacewalk
dnf remove dnf-plugin-spacewalk
# Clean cache again
yum clean all
dnf clean all
# Test the fix
yum update
Precautions
WHM/cPanel Users: Cleaning the cache or removing the plugin will not affect WHM, cPanel, or associated services (e.g., LiteSpeed, CloudLinux's LVManager).
Backups: Always back up your server before making significant changes.
