aio-clamav clamd.sock can't be created in /run/clamav/

The all-in-one (AIO) Nextcloud container is a comprehensive solution for hosting Nextcloud on a single container. However, users have reported issues with the ClamAV plugin, specifically with creating the clamd.sock file in the /run/clamav/ directory. In this article, we will explore the issue, its causes, and potential solutions.

When attempting to start the ClamAV plugin in the AIO Nextcloud container, users encounter an error message indicating that the clamd.sock file cannot be created in the /run/clamav/ directory. The error message is as follows:

2025-05-18T18:19:37+02:00 ERROR: Sun May 18 18:19:37 2025 -> LOCAL: Socket file /run/clamav/clamd.sock could not be bound: Permission denied
2025-05-18T18:19:37+02:00 ERROR: Sun May 18 18:19:37 2025 -> Can't unlink the socket file /run/clamav/clamd.sock

To reproduce the issue, follow these steps:

  1. Set up the AIO Nextcloud container using podman according to the instructions provided in the AIO documentation.
  2. Activate the ClamAV plugin.
  3. Start the containers via the AIO interface.

The expected behavior is that the ClamAV plugin should start successfully, and the clamd.sock file should be created in the /run/clamav/ directory.

However, the actual behavior is that the ClamAV plugin fails to start, and the error message indicates that the clamd.sock file cannot be created in the /run/clamav/ directory.

One potential solution to this issue is to modify the LocalSocket value in the clamd.conf file to point to a different directory, such as /tmp/. This can be done by running the following command:

find . -name "clamd.conf" -exec sed -i 's/LocalSocket \/run\/clamav\/clamd.sock/LocalSocket \/tmp\/clamd.sock/g' {} \;

This will modify the clamd.conf file to use the /tmp/ directory instead of /run/clamav/. However, this may not address the underlying issue and may only provide a temporary solution.

The underlying issue appears to be related to the permissions and ownership of the /run/clamav/ directory. The user clamav is unable to create the clamd.sock file in this directory, despite having the necessary permissions. This suggests that there may be a configuration issue or a bug in the AIO Nextcloud container that is preventing the clamav user from accessing the /run/clamav/ directory.

In conclusion, the issue with the clamd.sock file not being created in the /run/clamav/ directory is a complex problem that requires further investigation. While modifying the Socket value in the clamd.conf file may provide a temporary solution, it does not address the underlying issue. Further research and debugging are necessary to identify the root cause of the problem and provide a permanent solution.

  • Host OS: Ubuntu Server 24.04 LTS
  • Docker run command or docker-compose file:
systemctl --user daemon-reload
systemctl --user start nextcloud-aio-mastercontainer

and then via start containers the AIO-interface (if not already started)

Yes, I use the current ghcr.io/nextcloud-releases/aio-clamav:latest, I completely deleted the image. It is quite confusing to me, as with touch /run/clamav/test the user clamav can create a file there. But just not the socket. But podman should also not intervene, as /tmp can be used, which has the same owner and usage rights. So while an "easy fix" would be changing the LocalSocket value, it might not fix the underlining issue.
aio-clamav clamd.sock can't be created in /run/clamav/ - Q&A

A: The issue is that the clamav user is unable to create the clamd.sock file in the /run/clamav/ directory, despite having the necessary permissions. This is causing the ClamAV plugin to fail to start.

A: The symptoms of this issue include:

  • The ClamAV plugin failing to start
  • An error message indicating that the clamd.sock file cannot be created in the /run/clamav/ directory
  • The error message includes a "Permission denied" error

A: The potential causes of this issue include:

  • A configuration issue with the AIO Nextcloud container
  • A bug in the AIO Nextcloud container
  • A permission issue with the /run/clamav/ directory
  • A issue with the clamav user's permissions

A: To troubleshoot this issue, you can try the following steps:

  • Check the AIO Nextcloud container's configuration to ensure that it is correct
  • Check the /run/clamav/ directory's permissions to ensure that they are correct
  • Try creating a file in the /run/clamav/ directory using the clamav user to see if the issue is specific to the clamd.sock file
  • Check the ClamAV plugin's logs to see if there are any error messages that may indicate the cause of the issue

A: The solution to this issue is to modify the LocalSocket value in the clamd.conf file to point to a different directory, such as /tmp/. This can be done by running the following command:

find . -name "clamd.conf" -exec sed -i 's/LocalSocket \/run\/clamav\/clamd.sock/LocalSocket \/tmp\/clamd.sock/g' {} \;

A: No, this is not a permanent solution. The underlying issue with the /run/clamav/ directory's permissions and ownership needs to be addressed in order to provide a permanent solution.

A: To prevent this issue from occurring in the future, you can try the following steps:

  • Ensure that the AIO Nextcloud container's configuration is correct
  • Ensure that the /run/clamav/ directory's permissions are correct
  • Ensure that the clamav user has the necessary permissions to create files in the /run/clamav/ directory
  • Consider using a different directory for the clamd.sock file, such as /tmp/

A: You can find more information about this issue checking the AIO Nextcloud container's documentation and the ClamAV plugin's documentation. You can also try searching online for solutions to this issue.
