but even when it is set to true, this does only work in a standard installation and not inside a docker container installation with PostgreSQL database:

root@abc:/var/xyz/mattermost# docker-compose exec app sh
~ $ mmctl user delete u78yrxgftpg89bwijmy6ez98we --confirm --local
Unable to delete user ā€˜usernameā€™ error: : Konnte die zu lƶschenden Nachrichten fĆ¼r den Benutzer nicht auswƤhlen.,
(Could not select the messages for the user to delete)

I have enabled [EnableAPIUserDeletion] still it is showing the sameā€¦I have installed omni installationā€¦ After changing config file do i need to change anything?? I tried restarting it and reconfigure it but still showing same errorā€¦

#4

Please take into account that Omnibus uses configuration in the database, so changing the config.json file has no effect on the applicationā€™s configuration.

Can you try to update the configuration running

mmctl config set ServiceSettings.EnableAPIUserDeletion true --local

and then try to delete a user again?

This was hard to find, I would like to put forward that it is published in the official documentation. Worked for me on the latest build.
