can't scan files

[Thatoo]

Describe the bug

As root, if I launch

sudo -u nextcloud php /var/www/nextcloud/occ files:scan administrateur

I get the following error

Exception during scan: opendir(/home/administrateur/media/stockage): failed to open dir: Permission denied

Steps to reproduce

As explained above

Expected behavior

Would like to scan all files of all users for keeweb to work...

Hi!

As we can see, you have a permission problem with /home/administrateur/media/stockage, what this file is?

Can you do:

ls -la /home/administrateur/media/stockage

[Thatoo]

ls -la /home/administrateur/media/stockage ou ls -la /home/OtherUser/media/stockage

give

total 32
drwx------ 5 admin root  4096 juin  14  2020 .
drwxr-xr-x 4 root  root  4096 août  17  2020 ..
drwx------ 2 admin root 16384 nov.  24  2018 lost+found
drwxr-x--- 2 admin root  4096 oct.  18 19:36 yunohost_backup_archives

[Thatoo]

it is as if all /home/$USER/media were symlink to /media. I guess it's not a nextcloud issue but a yunohost thing. Is it normal situation?

[Thatoo]

I believe that sudo -u nextcloud php /var/www/nextcloud/occ files:scan administrateur should not scan /home/administrateur folder but /home/yunohost.app/nextcloud/data.administrateur, no?

What do you think @kay0u ?

In /var/www/nextcloud/config/config.php, it is set 'datadirectory' => '/home/yunohost.app/nextcloud/data',

[Thatoo]

@kay0u /home/administrateur/media/stockage Is my external hard drive where I store all Yunohost backup. Of course nextcloud should not scan these files. Do you know how to tell nextcloud to avoid scanning these files?
