[Bug]: Cron "Some jobs have not been executed since X days." even though cron.php run every 5 minutes

[vasyugan]

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

Nextcloud says that some background jobs have not been executed since 6 days, even though cron.php is executed by www-data every 5 minutes.

Furthermore, changing the cron mode to webcron also fails:

occ background:webcron

In AppConfig.php line 823:
                                                          
 conflict between new type (mixed) and old type (string)  
                                                          

background:webcron

When I manually execute sudo -u www-data php -f cron.php, the command exits immediately

Steps to reproduce

I have no idea how to reproduce this. The error just occurred after migrating this nextcloud instance from another server.

Expected behavior

should just work™.

OK, this looks like a duplicate of #45083

[joshtrichards]

See #45083 (comment) if you need to toggle the mode in the meantime for a workaround.

I guess close this out once you're comfortable it's covering the same territory as that issue. :-)
