⭑⭑ SNAP confinement does not allow access to /mnt by default. SNAP confinement limits file system access to $HOME and /mediaonly. DO NOT USE the SNAP package if you plan on processing file paths that start with /mnt. ⭑⭑
--edge … use latest release channel --devmode … disable confinement to allow full access to your file system(otherwise snap confinement will default to Strict and limit file system access to your $HOME folder)
