Nextcloud (Snap) 0770 Permission Denied on rclone Google Drive Mount (chown has no effect)

[Kadir_Gokduman]

Post Content:

Hello everyone,

I am facing a permission issue with Nextcloud installed via Snap, and I would really appreciate some guidance.

System Information

• OS: Debian (latest stable)

• Nextcloud installation method: Snap

• Storage: Google Drive mounted using rclone

• Mount type: rclone mount (FUSE)

---

What Happened

Initially, I installed Nextcloud using Docker, but I encountered API-related errors. Because of that, I switched to the Snap version of Nextcloud.

Since my local disk space was insufficient, I mounted my Google Drive using rclone and configured it as storage.

Interestingly:

• Immich works perfectly with the same mount.

• However, Nextcloud throws a permission error (0770).

---

The Problem

Nextcloud reports a permission error related to directory access (0770).

Even when I run:

chown -R www-data:www-data /mounted_directory
chmod -R 0770 /mounted_directory

The ownership and permissions do not actually change. It seems like the permissions are not being applied to the mounted directory.

---

What I Suspect

I suspect this might be related to:

• Snap confinement restrictions

• UID/GID mismatch

• rclone FUSE mount permissions

• AppArmor limitations

---

My Questions

1. Is Snap Nextcloud allowed to access rclone FUSE mounts by default?

2. Do I need to connect additional Snap interfaces?

3. Should I mount rclone with specific uid/gid parameters?

4. Is there a recommended way to use Google Drive as primary storage with Snap Nextcloud?

---

Any help would be greatly appreciated.
Thank you in advance

Storage: Google Drive mounted using rclone

Pay special attention to the docs pertaining to mounting external media and permissions / privileges:

How to manage external media and storage for Nextcloud snap

Managing external media and storage Snap confinement is a security feature and determines the amount of access an application has to system resources, such as files, the network, peripherals and services. Thus your Nextcloud snap is securely confined from the host system. Unless you specifically allow the Nextcloud snap to access the /media or /mnt directories on the host system, you will not be able to access any other directory outside of the confinement. External media, network shares and s…

What permissions should external media have?

See FAQ’s and Snap confinement

Removable media or external storage must be mounted to either /media or /mnt as root with root permissions and connected to Snap!

The interface providing the ability to access removable media is not automatically connected upon install, so if you’d like to use external storage (or otherwise use a device in /media or /mnt for data), you need to give the snap permission to access removable media by connecting that interface:

sudo snap connect nextcloud:removable-media
