probably did something stupid… and I’m hoping that somebody can help me.
but from the beginning:
i edited a note in the “notes” app on the web interface.
For some reason I suddenly got the error message that the file is locked and can’t be saved anymore (I don’t have the exact wording of the message anymore)
then tried to delete the file. But it did not work because the file was locked. Not even after a reboot.
Then I tried to delete the whole directory via console:
sudo rm -r /var/www/nextcloud/data/XXXXXX/files/Notes/Allgemein/TEMP.txt
That worked, the directory is gone. BUT I can’t create a new folder with the same Name now. “The folder could not be created […]”
Looks like it still exists and it is locked.
How can I unlock it?

No real idea. But i think it is still in the database.
Have you re-scan “all” or the “user”?

sudo -u www-data php occ files:scan --all
sudo -u www-data php occ files:scan username
