Version 4.0.17

Released: October 18, 2021

Status: Maintenance



A new icon driver was added to support stacked Font Awesome icons.


The usage .user.has_usable_password was fixed. This solves the “Change Password” link not being disabled when using external authentication.


Support was added for COMMON_EXTRA_APPS_PRE. This setting works like COMMON_EXTRA_APPS but installs the new apps before the default apps. This allows the extra apps to override templates and other system data.

Support for blank/empty app URL namespaces was added. These are used to register the urlpatterns of encapsulated libraries as top level named URLs.

The user_settings folder is now created and initialized on upgrades too.

The error handling logic of the initial folder creation was improved.


Asset image cache creation was fixed. Allows using assets for decorations in all cases.


The MAYAN_GUNICORN_TEMPORARY_DIRECTORY environment variable is now exported and available to supervisord in all cases.

The owner of the /var/lib/mayan/ is now always changed on container startup. This ensures that the mayan operating system user can always read and write from and to the mounted volume.


The migration from version 3.5.x to 4.0.x was improved to ensure only one document version per document is active after the migration.


The help texts of the ORGANIZATIONS_INSTALLATION_URL and ORGANIZATIONS_URL_BASE_PATH settings were expanded to better explain their functions.


A workaround for a swagger-spec-validator dependency bug was backported from version 4.1. The library jsonschema is now pinned to version 3.2.0 to avoid errors with swagger-spec-validator 2.7.3. swagger-spec-validator does not specify a version for jsonschema (, which installs the latest version of jsonschema, 4.0.1. This version removes jsonschema.compat still used by swagger-spec-validator.


  • Add project_url attribute to the Python setup file.

  • Move the filesystem touch function to the storages app.

  • Add Redis restart step to the upgrade instructions.

Upgrading from Mayan EDMS 3.5.x


Supervisord must be upgraded to version 4.2.2. See troubleshooting section: After upgrade to version 4.1

  1. Stop supervisord:

    sudo systemctl stop supervisor
  2. Make a backup of your supervisord file:

    sudo cp /etc/supervisor/conf.d/mayan-edms.conf /etc/supervisor/conf.d/mayan-edms.conf.bck
  3. Make a backup of your database:

    Use the respective backup command for the database:

  4. Upgrade to the latest pip version:

    sudo --user=mayan /opt/mayan-edms/bin/pip install --upgrade pip
  5. Remove deprecated requirements:

    sudo --user=mayan curl --output /tmp/removals.txt \
    && sudo --user=mayan /opt/mayan-edms/bin/pip uninstall --requirement /tmp/removals.txt --yes
  6. Update the Mayan EDMS Python package:

    sudo --user=mayan /opt/mayan-edms/bin/pip install mayan-edms==4.4.7

    the requirements will also be updated automatically.

  7. Update the Redis configuration to serve at least 3 databases:


    databases ...


    databases 3
  8. Restart Redis for the changes to take effect:

    sudo systemctl restart redis
  9. Edit the config file at /opt/mayan-edms/media/config.yml:




    LOCK_MANAGER_BACKEND: mayan.apps.lock_manager.backends.redis_lock.RedisLock
    LOCK_MANAGER_BACKEND_ARGUMENTS: {'redis_url':'redis://:mayanredispassword@<IP address of Redis server>:6379/2'}
  10. Update the supervisord configuration file. Replace the environment variables values shown here with your respective settings. This step will refresh the supervisord configuration file with the new queues and the latest recommended layout:

    sudo --user=mayan MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
    /opt/mayan-edms/bin/ platformtemplate supervisord | sudo sh -c "cat > /etc/supervisor/conf.d/mayan-edms.conf"
  11. Edit the supervisord configuration file and update any setting specific to your installation:

    sudo vi /etc/supervisor/conf.d/mayan-edms.conf
  12. Migrate existing database schema and static media files with:

    sudo --user=mayan MAYAN_MEDIA_ROOT=/opt/mayan-edms/media/ \
    /opt/mayan-edms/bin/ performupgrade
  13. Start supervisord:

    sudo systemctl start supervisor
  14. Clear the browser cache to avoid loading old web assets.

The upgrade procedure is now complete.

  • mayan.apps.file_caching.models.CachePartitionFile.DoesNotExist: CachePartitionFile matching query does not exist.


  • FileNotFoundError: [Errno 2] No such file or directory: '/var/lib/mayan/document_file_storage/...
