How to install Kindle on Ubuntu 18.04?
I installed Kindle on Ubuntu 18.04.2 LTS easily by first installing wine using the following commands:
$ sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
$ sudo apt-get update
$ sudo apt-get install --install-recommends winehq-stable
$ wine --version
should be wine-4.0
If there are GPG error, follow steps from https://wiki.winehq.org/Ubuntu .
Then download Kindle version 1.17.44183 from the following site and save to your desktop: (It must be this version)
https://kindle-for-pc.en.uptodown.com/windows/download
Right click the Kindle downloaded on your desktop and select install with wine. The program will create two desktop links (desktop.lnk and kindle.lnk) You can use either link, however the desktop.lnk, you will be able to add to your favorites on the side panel. Save the 1.17.44183 download in case you need it again later. Thats all!
I tried Eric's suggestion to open https://read.amazon.com/ (Kindle Cloud Reader) and convert it to an app with nativefier. This worked like a charm. Read the documentation on the nativefier page (https://www.npmjs.com/package/nativefier) to learn how to use it.
