Yes … Learn Linux and use a modern Debian install. WD hardware is fine. The WD software is abysmal at best. See Clean OS (Debian), OpenMediaVault and other "firmwares" - #1748 by hippyfox for alternative firmware aka OSes for WD hardware.
If you want to stick with the WD firmware the chroot app is nice hack to get an environment where apt-get works but you need to be somewhat familiar with Linux to use chroot and install new packages.
