occ files_external:delete on external smb storage fails with php fatal error

[dirks]

Steps to reproduce

1. ensure you have a smb external storage configured (in this example it has the mount_id 4
2. try to delete the external storage via occ files_external:

   sudo -u www-data php /var/www/nextcloud/occ files_external:delete -- 4

Expected behaviour

The specified external storage is deleted. Exit state of occ is 0.

Actual behaviour

The external storage remains and an error message is displayed:

PHP Fatal error:  Declaration of Symfony\Component\Console\Input\ArrayInput::hasParameterOption($values, bool $onlyParams = false) must be compatible with Symfony\Component\Console\Input\InputInterface::hasParameterOption($values, $onlyParams = false) in /var/www/nextcloud/apps/news/vendor/symfony/console/Input/ArrayInput.php on line 202

Note, removing the storage via the web interface works.

I never run into that issue but I know the problem. news app has feed-io (a library to parse rss feeds) as dependency and feed-io has symfony-console as dependency but symfony-console is also a nextcloud dependency. If the news app is installed two versions of symfony-console are installed and there are not compatible with each other.

cc @ChristophWurst could the news app use something like https://stackoverflow.com/questions/18882201/how-does-the-replace-property-work-with-composer to prevent composer from installing the symfony/console as dependency?
