Can SickBeard be installed on EX4?

No problem, sorry I couldn’t help you out. It appears that even though documentation suggests the EX4 has docker support, it isn’t functional at this point in time according WD staff. The CIFS error is completely unrelated by the way, the network connection error is just a generic error whenever WD has a problem with the app container in my experience.

the SDK is build on Docker containerization, but Docker is not working / being availbale on EX4.
If you want to participate, even with being listed as official Third-Party App, then your platform is Marvell ARMADA 385 of My Cloud Mirror Gen.2 and EX2100, Marvell ARMADA 388 of EX4100 or Intel Atom C2350 (DL2100) and Intel Atom C2338 (DL4100).
