Introduction

If you're trying to install Spamassassin on your Ubuntu 20.04 system and encountering the error chmod: cannot access '/var/lib/spamassassin/compiled': No such file or directory, you're not alone. This specific issue is often linked to permissions and configuration problems within the installation process. In this guide, we’ll investigate the cause of the problem and guide you through the solution to get Spamassassin up and running smoothly.

Understanding the Problem

When you run the command apt install spamassassin spamc, the installation process runs a script called sa-compile that compiles the configuration needed for Spamassassin. If the directory /var/lib/spamassassin/compiled is missing or inaccessible, the installation will fail with the aforementioned error message.

The specific error can cause a chain reaction, impacting subsequent installations and updates to related services like spamass-milter or amavis.

Key Points of the Issue:

Error Message: chmod: cannot access '/var/lib/spamassassin/compiled': No such file or directory

Behavior after Error: Successful manual execution of sa-update and sa-compile does not resolve underlying installation issues.

Repeated Problems: Leading to corruption and removal of necessary directories during service installations.

The Root Cause

After exploring the issue, the root cause has been identified as a damaged start-stop-daemon. This component is crucial as it interfaces with service management tasks on your system. If it is malfunctioning, the services dependent on it, like Spamassassin, face failures during installation or reconfiguration.

Identifying the Damaged Daemon

Understanding the malfunctioning of this daemon can be tricky, but the symptoms are clear – errors during package installations, unexpected directory removals, and permission-related issues.

The Solution

To resolve this installation problem, follow the steps below:

Step 1: Replace the Damaged Daemon

The most effective solution is to replace the faulty start-stop-daemon. Use the following commands to replace it:

Watch for any errors during this step. If successful, Spamassassin should complete the installation without the previous issues.

Step 4: Restart the Server

It’s a good practice to restart the server after making significant changes to the core components. This helps to apply all configurations and ensures that all services start fresh:

Conclusion

Resolving the chmod: cannot access '/var/lib/spamassassin/compiled' error on Ubuntu 20.04 boils down to addressing the damaged start-stop-daemon. By replacing the broken daemon and ensuring proper reconfiguration of services, you can successfully install and run Spamassassin along with related services.

If you continue to experience issues even after these steps, consider reaching out to your hosting provider or reviewing the installation logs for additional insights. With patience and the right steps, your server can be a spam-free zone once again!
