Migration isues FAQ

This page lists all the known issues encountered after a migration from YunoHost 11 to 12.

If the suggested solutions don't work, please ask for help.

Python appsโ€‹

After upgrading, some python apps should be unavailable because their virtual environment (venv) needs to be rebuilt.

To do that you can run the pending migrations in Webadmin > Update.

In addition, the apps below won't be automatically repaired, you need to force-upgrade them manually instead, with yunohost app upgrade -F APP.

Apps which won't be automatically repaired and need a force upgrade:

  • borgserver and all its instances (eg. borgserver__2, borgserver__3, ...)
  • borg (Borg on the app store) : rebuilt using yunohost app upgrade -F borg (otherwise, will sent emails notifying that "The backup miserably failed to backup", with error ModuleNotFoundError: No module named 'borg')

TODO: list those apps

FIXME:??!!! If needed, you can disable the automatic rebuild for a specific python app, by removing the dedicated file ending with .requirements_backup_for_bullseye_upgrade.txt before applying the migration. You can find this file near the venv (Python virtual environment) of your app inside /var/www.

Error 500 everywhereโ€‹

The web server, nginx, might need a restart before being fully operational. Please run this command:

sudo systemctl restart nginx

A manual change in a configuration file is needed for Mailman3 to work, see the relevant issue.
