Dear Ubuntu users, May I ask your kind help in order to solve the following issue: I am looking for a possibility to install the software of the ePub format on a new Kindle Paperwhite 4 e-book reader, if this is possible at all. I appreciate any un

I would install the snap package:
FB reader first to see if it reads the book.
For Ubuntu only to read Ebooks
Easy to install or remove.

The kindle devices are not running the Ubuntu operating system but something else, which allows only very restricted modifications. If you want to install a program that can read epub files on the kindle, you have to hack the device (not recommended).

The better possibility is installing calibre on your Ubuntu system, using it for converting the epub file into the kindle format (as far as I know Mobi/AZW3), and then transferring that file to your kindle device.

Thank you, Bernard,
Installation have been made
and I will follow your advice
Regards

Thank you, Manfred,
This is the answer that I expected in case the
direct installation is not possible. I am going to
acting this way and thank you for confirming the
idea
