Bug description

PHP Fatal error: Declaration of Stecman\Component\Symfony\Console\BashCompletion\CompletionCommand::mergeApplicationDefinition($mergeArgs = true) must be compatible with Symfony\Component\Console\Command\Command::mergeApplicationDefinition(bool $mergeArgs = true): void in /var/www/nextcloud/3rdparty/stecman/symfony-console-completion/src/CompletionCommand.php on line 57

Steps to reproduce

After upgrading to version 6.1.1 and updating Next cloud to 28.0.3, I receive a message in the admin panel about the need to download models (they were downloaded earlier and everything worked fine). When trying to run in /var/www/next cloud "sudo -u www-data php c recognize:download-models" I get the following message "PHP Fatal error: Declaration of Stecman\Component\Symfony\Console\BashCompletion\CompletionCommand::mergeApplicationDefinition($mergeArgs = true) must be compatible with Symfony\Component\Console\Command\Command::mergeApplicationDefinition(bool $mergeArgs = true): void in /var/www/nextcloud/3rdparty/stecman/symfony-console-completion/src/CompletionCommand.php on line 57"

Looks like we need to bump it since we're still on v0.11.0:

stecman/symfony-console-completion#95

[joshtrichards]

Though I think they're incorrect in the associated PR re: this only impacting Symfony 6.x, as we're on 5.x. Unfortunately they only fixed it in a version of stecman that isn't compatible with Symfony 5.x. I've asked if they can backport to a a 0.11.x release.

For what it's worth, I don't think this is new bug in v28.0.3. The Symfony 5.x code base has had defined this way for a LONG time. Our recent minor Symfony bump doesn't look like it introduced this.

Hello,
I'm facing the exact same problem, however I have multiple Nextcloud 28 instances on the same server and only one of the two is impacted. The Nextcloud files are identical.

I came to the conclusion that an app caused the issue.
Backup your database, note the enabled app, then disable them all.

update oc_appconfig set configvalue="no" where configkey ="enabled";

Enable each one from the interface while checking if the occ command is now working as expected every time.

On my side, it was an on-development app that caused the issue, so I can't really point you the faulty one on your side.

EDIT and follow-up: turns out it was a dev dependency that was shipped in the app (symfony/console > 6.0), more like an error from our side. Can still be a hint for your own case.
