Some helping notes regarding Calibre and Amazon Kindle

[Member ctcx]

I was asked a simple task with a Kindle Paperwhite: uploading some books to the device via USB; i.e., sideloading.

Surprises, surprises:
—the Kindle ever-lasting cover-removing bug –solved with Calibre
—Calibre being unable to properly write to the device –DBus/polkit “Not Allowed” errors, and device always prematurely force-unmounting (possibly due to aforementioned errors?), so half of stuff was never uploaded, unless running Calibre with sudo

This was a hell, and still today I don’t want to see that piece of **** again –I gave it back after completing the task.

However I wondered if some of the learning I got could be useful for some future users, so tried to “report” here.

First, install Calibre manually instead of from repo (suggestion coming directly from the dev):
https://calibre-ebook.com/download_linux

Alas, Calibre is designed to work with udisks2, and udisks2 works with polkit…
Install packages policykit-1 and udisks2.
Polkit needs configuration for permissions…
Taken/based from here:
https://igurublog.wordpress.com/downloads/script-devmon/ (section “Troubleshooting UDisks”)
create file /etc/polkit-1/localauthority/50-local.d/10-udisks.pkla , including subdirectories if needed, with this:

[udisks2]
Identity=unix-user:demo
Action=org.freedesktop.udisks2.filesystem-mount;org.freedesktop.udisks2.encrypted-unlock;org.freedesktop.udisks2.eject-media;org.freedesktop.udisks2.power-off-drive;org.freedesktop.udisks2.filesystem-unmount-others
ResultAny=yes

AntiX, or overall Debian-based, seem to still be using Policykit (legacy v1) instead of Polkit (current v2).

With this Calibre should be able to mount/unmount, and without conflicting with udevil.

Forgot one detail: the calibre_postinstall script needs package libopengl0 as installed dependency in order to work properly and not throw errors/warnings.
