Kindle Conversion error

[cloudhopper]

I've used our tool many times with great results, thanks for all of your work!

Today I tried to convert as usual but was met with the error below:
I'm on Ubuntu linux using Kindle for PC (version 1.15.0 last updated 11/18/2018). Can someone help me determine if this is a DRM related error or something else?

Thanks,
Jason

DRMError: Ancillary Mercy (Imperial Radch)

Book is DRM infested.
You need to visit Apprentice Alf
(that is all we can say here: MR Rules)

Incidentally, this also has pretty much nothing to do with the Kindle Collections plugin .

On the other hand, the dedicated Conversion Calibre subforum sounds like a good match .

Good catch. I have moved it.
