For Linux users: I guess I'm fortunate in that I use Arch, and I've never had any problems with Calibre. But for those that do:
Can I suggest you try the Flatpak package for Calibre:

Flatpak is supported on every Linux distro, and it does a good job of bundling the application with everything it needs to function correctly, regardless of the system it's running on.
