Recently, app-text/calibre, with the DeDRM plugin installed, has failed to remove DRM when importing amazon.com purchased ebooks. Looking at calibre's debug mode logs, I think the error is: ModuleNotFoundError: No module named 'Crypto' After some googling of this error, I emerged dev-python/pycryptodome, and it looks like this fixes the problem. Could this be made a dependency of calibre, maybe via a use flag? I realize this is a dependency of the DeDRM plugin, not calibre itself, but I imagine most Gentoo users with calibre also use this plugin. emerge --info: Portage 3.0.17 (python 3.8.8-final-0,

What procedure do you use to install the plugin? Are installation and updates entirely manual, as described here? https://github.com/apprenticeharper/DeDRM_tools/blob/master/CALIBRE_CLI_INSTRUCTIONS.md#install-plugins > #### Install plugins > - Download the DeDRM `.zip` archive from DeDRM_tools' > [latest release](https://github.com/apprenticeharper/DeDRM_tools/releases/latest). > Then unzip it. > - Add the DeDRM plugin to Calibre: > ``` > cd *the unzipped DeDRM_tools folder* > calibre-customize --add DeDRM_calibre_plugin/DeDRM_plugin.zip > ``` > - Add the Obok plugin: > ``` > calibre-customize --add Obok_calibre_plugin/obok_plugin.zip > ``` I imagine that we can create an ebuild to automate updates and pull in the dev-python/pycryptodome dependency.
Yes, it is just a manual install following those instructions. I think, due to possible legal concerns, the calibre devs do not want to be "officially" associated with the DeDRM plugin, so, unlike other plugins, it cannot be installed using calibre's list of user plugins. I was not intending to ask for the ebuild to actually install the plugin, just add dev-python/pycryptodome as a dependency.
I have just recently implemented https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=5a1aae1fc67dd51c2789e11b8f7dc156d62d8b8d This sets up gentoo to support: https://github.com/kovidgoyal/calibre/pull/1284 It is now possible to package arbitrary calibre plugins as ebuilds, install them to /usr/share/calibre/system-plugins, and have them automatically loaded and centrally managed. Maybe you'd like to make an overlay for this plugin?
