For future records (in case anyone has the same question).
To make Optware work on My Cloud, especially if it’s using firmware 4.x, a new feed specific for this device would be required, since it uses a modified kernel image with non-standard 64k sized memory pages. WD provides sources and toolchain for this, but I honestly doubt that anyone will take the task to do that.
The alternative is to stick with the built-in apt package management system, but this also requires (at the moment) that packages are rebuilt from source, at least until someone comes with a “repository” of pre-built packages.
A guide to build packages from source for the My Cloud (firmware 3.x or 4.x) is here:
Unfortunately WD did a big mistake, IMHO, by making installing third-party software so hard to achieve on this device. However it’s fair to say that I was contacted by the WD technical support who proposed me a refund if I’m not satisfied with this product, although we’re talking about a feature which is explicitely declared as not supported by the manufacturer. I appreciated this and I think I’ll trust again WD in the future, although, as I said, they’re missing the opportunity to please advanced (but still consumer) users with this device, which is in a segment where WD has almost no competitor (other solutions from other manufacturers are usually different in terms of price, size and complexity of the solution).
