System: CentOS 7.7.1908
PHP: PHP 7.3.13

sudo -u apache php /var/www/html/cloud/occ app:enable files_mindmap

PHP Fatal error:  Declaration of Symfony\Component\Console\Output\NullOutput::write($messages, bool $newline = false, int $options = self::OUTPUT_NORMAL) must be compatible with Symfony\Component\Console\Output\OutputInterface::write($messages, $newline = false, $options = 0) in /srv/www/html/cloud/apps/news/vendor/symfony/console/Output/NullOutput.php on line 25

any hint, suggestion? help is welcome!

Which Nextcloud version are you running?

Please check web interface and see if your app is compatible with your NC version.

Just checked

Which one is it? Both are not available for NC18

Pardon: NC 17.0.2

maybe you have installed the wrong version… there’s one “MindMap” and another one “Mind Map”. the latter one seems to be the right one

I get the same error on Gentoo with PHP 7.3 it NC 18. I know it isn’t officially supported, but I was trying anyway. I didn’t have any issue with NC 17.0.2, but I enabled it via the web interface.

To clarify I referring to files_mindmap at
