I used

Code:

nix-shell -p openssl calibre --run calibre

This stands up a temporary environment that contains both openssl and calibre, and runs calibre. Because I've got both in my configuration.nix, they're already installed and nothing needs to download. It just starts up and works.

I think this can also be accomplished with a flake, but I'm still learning a ton, so I don't have that figured out yet. For now, I just edited my calibre .desktop file to use the nix-shell command and it just works.

Thank-you. It looks like that worked. I am also trying to figure out what you can do with flakes. Maybe figuring out how to do this with a flake will provide some motivation.

I'm a *very* new user to Calibre - I can't d/l the ACSM Input plugin. The error told me to post this to the forum. I read as many posts as I could bear and downloaded some zip files containing py files, but I'm not sure what to execute. Can you help?
calibre, version 7.6.0
ERROR: Install plugin failed: A problem occurred while installing this plugin. This plugin will now be uninstalled. Please post the error message in details below into the forum thread for this plugin and restart calibre.

The relevant part of the log is

Code:

_openssl/_libcrypto_ctypes.py", line 47, in <module>
    raise LibraryNotFoundError('Error detecting the version of libcrypto')
oscrypto.errors.LibraryNotFoundError: Error detecting the version of libcrypto

libcrypto is usually part of openSSL You could try installing openSSL.

Or you could try downloading the current Calibre package for your system, see https://calibre-ebook.com/download

(Calibre 7 is really quite old. the current version is 9.3.1!)

Install openSSL and calibre 9.3.1 and then try again. Do not download calibre from any distro. Download it from the official calibre website.
