Nextcloud version (eg, 12.0.2): 15.0
Operating system and version (eg, Ubuntu 17.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): ?
PHP version (eg, 7.1): ?
The issue you are facing:
I installed Nextcloud on Ubuntu using SNAP and now I can’t set up a local folder as external storage on Nextcloud: I’m following the guide, and already ran the following commands:
sudo chown -R www-data:www-data /home/david/Descargas/
sudo chmod -R 0750 /home/david/Descargas/
sudo -u www-data bash
cd /home/david/Descargas/
mkdir data
I also added the folder as external storage:
But then Nextcloud doesn’t even see it:
Am I doing something wrong?
Is this the first time you’ve seen this error? (Y/N):
Yes.
Steps to replicate it:
- Add local external storage
- Try to use it.

The output of your Nextcloud log in Admin > Logging:

(The editor won’t let me paste text that long)
The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

The output of your Apache/nginx/system log in /var/log/____:

(Not sure where to find this file)



my next guess was the snap causing the issue, presumably because of the sandboxing that snaps do. You should be able to use USB storage so long as the permissions are correct
