Yes i use samba and nfs shares that are mounted locally by ubuntu server to local mountpoints
accessible through www-data
Are you using encryption: yes/no -> NO
Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/... LDAP
With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config

Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';
Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.

The files that has to be deleted are all tagged by systemtag "to-be-deleted-next-cron"
In earlier versions each day the files that has been tagged like this had been deleted reliable through the system.
Since use of the nescessary version 1.9.0 (1.8.5 was incompatible to nextcloud 20.x) the errors above are comming each cronjob into the logs.
The files still are tagged as mentioned but the system doesn't delete the files / folders!
