Because SNAP applications run inside of a sandbox they have different set of permissions.
If you try to browse to a Network share (NFS/Samba) or Removable share (USB/External drive) and Obsidian shows an error “Permission Denied” and you can access the files via file explorer follow the steps below to fix it.
Luckily the great developers at Obsidian have added the correct permissions you just have to enable it.
- Open Ubuntu Store
- Go to installed tab
- Find and open Obsidian
- click “Permissions”
- Enable “Read/Write files on removable storage devices”
- Close out of Ubuntu Store
You should now have access to browse removable media.
