when I install the kiwix server docker container show error Unable to add the ZIM file zim to the internal library

There could be a few reasons why you are encountering this error when installing the Kiwix server docker container. Here are some steps you can try to resolve the issue:

1. Check the file path: Make sure that the ZIM file you are trying to add is located in the correct file path. By default, the Kiwix server looks for ZIM files in the /library folder. If your file is located somewhere else, you will need to specify the correct path when adding it to the library.

2. Check file permissions: Make sure that the ZIM file has the correct file permissions. The file should be readable by the user running the Kiwix server container. You can check and adjust file permissions using the chmod command.

3. Check container logs: Check the container logs for any error messages that might give more information about the issue. You can use the docker logs command to view the logs for the container.

4. Try a different ZIM file: If you are still having trouble adding the ZIM file to the library, try using a different ZIM file to see if the issue is specific to that file.

5. Rebuild the container: If all else fails, you may need to rebuild the Kiwix server container from scratch. Make sure to follow the installation instructions carefully and ensure that all dependencies are installed correctly.
