Sideloading kepub from Android is not picked by Kobo

sup · 04-12-2025, 07:03 AM

I have Calibre installed in Termux on android, I use it on the command line. I installed the kepub output plugin. I download the economist with a recipr when on the road.

Downloading epub and mobi works. When I connect the phone and kobo with USB-C cable and put them into the root directory I see there, they get picked up by Kobo. But with Kepub, Kobo does not see the file. Any idea why? I am genuinely puzzled.

The file extension must be .kepub.epub instead of .kepub. Just rename the files.

Aha, simple, thanks. Is there any way to produce a file named like that in one go from calibre (without running sed or just plain mv through a pipe, which I guess I will do otherwise)

Not that I know of, but this doesn't mean there isn't one. Maybe someone else knows more.
