Nextcloud 19.0.1 Problem with deleting files/folders

[triver]

I first tried following the next instruction:

File is locked - how to unlock

Hi amo13 I had the same Problems a few times. But I could always fix it with this procedure (retain the order!): occ ‘files:scan --all’ occ ‘files:cleanup’ occ ‘maintenance:mode --on’ mysql -u root -p’inheregoesyourpassword’ -D ocdb -e ‘delete from oc_file_locks where 1’ occ ‘maintenance:mode --off’ restart your Nextcloud webserver and try again -> the files in your web-ui should be gone. Good Luck, Cheers zisuu

Which at step one resulted in mayor errors and the process being killed:

Starting scan for user 1 out of 3 (Some_user_without_groupfolder_access)
Starting scan for user 2 out of 3 (Some_user_with_Groupfolder_access)
    Exception during scan: An exception occurred while executing 'SELECT `fileid` FROM `oc_filecache` WHERE (`storage` = ?) AND (`path_hash` = ?)' with params [1, "1e6013faa7e8570d55f5164261dc1b4d"]:

After this i tried the next proposed solution which actually solved some problems (but not all).

File is locked - how to unlock

solved the issue for me, thanks. sudo -u www-data php occ maintenance:mode --on (in Nextcloud folder) sudo redis-cli -s /var/run/redis/redis.sock flushall (OK was response) exit sudo -u www-data php occ maintenance:mode --off (in Nextcloud folder) sudo -u www-data php occ files:scan --all (in Nextcloud folder) But there was no password in redis? Is this right?

Then I went back to the first procedure, which this time didn’t cause any errors.
But still didn’t solve the problem.

So to be clear:

The newer problem in my log file named (and occured after my initial post):

OCP\Files\NotPermittedException: Could not create path

Is SOLVED with the instructions.

But the one in my log file that is named:

Exception: Failed to move groupfolder item to trash

Still occurs…

I do not wish to move this question to another topic, as i’m quite sure it is a problem on it’s own that has not been solved yet… (or that i’m aware of after frantically searching for a solution on the forum.)

Is there any more information that can help search for a solution?

Thanks a lot.
