I always used Enigmail successfully with Thunderbird on Fedora KDE Plasma
But, since I created some subkeys in order to use a Nitrokey Pro as secondary signing device, I have been unable to sign/encrypt emails with regular passphrase entered in pinentry-qt.
I mean, for example I don't have Nitrokey Pro plugged into the computer because I want to use the regular privatekey that is on the system: Thunderbird instead of prompting me for private key passphrase, it shows me error message "encryption command failed". In logs I could see FAILURE sign 100663404, that leads to this bugreport https://sourceforge.net/p/enigmail/bugs/673/

Thank you
If you have gpg-error installed (it's unfortunately often not part of the distributions), you get the following result for the error code 100663404:
In other words, it's a card error, and the error stems from the card daemon (scdaemon). That's as much as I can tell.
I will try to ask in GPG mailing list and I will let you know about.
Thank you
