Obok DeDRM doesn't work on some installs of Calibre for Linux

[tacosauce]

I'm at a bit of a loss here, when I try to run Obok DeDRM from the officially sourced install, it fails to find the necessary userkeys for the desktop app. However, if I run Obok using the install sourced from pacman, it works as it should. I'm currently running CachyOS(Arch) Linux, and I also have a second partition with Linux Bazzite where Obok functions normally from the official install.

So far I've tried: Installing the same version thats available on pacman(8.7), using an isolated install, uninstalling the pacman version but leaving the dependencies before installing the official binary, running the install of Calibre I have installed on a different OS partition, and installing a different version of Obok. None of it works other than running Calibre from pacman and I'm not sure whats so different that makes the plugin unhappy.

Here are some outputs from the terminal:

Calibre 8.15

The solution is to remove Obok. In calibre, install ACSM Input and DeDRM. Then once you have everything properly configured, download ePub from Kobo. Don't download KePub. Then you can use calibre to convert your ePub to KePub as you send to your Kobo.

I figured it out. Calibre comes with an older version libreadline, which causes a error when used with the latest version of bash. Replacing or deleting that and libncursesw fixes the issue.

Your post is of little help to the OP.

What if the ebook you are wanting does not have a download option? And remembering that unless you keep your Kobo offline or in sideload only, it is going to sync with Kobo.
