Pinentry- problem with generating a pair of keys

[bohorok]

I can't generate a pair of keys.

Platform : archlinux
gpg version: 2.4.8
pinentry version: pinentry-gtk2 (pinentry) 1.3.2
gpgfrontend version: v2.1.9

When i probe generate a new pair of keys i give announcement in window:

Error code: 85
source: no source
description: no pinentry

command:
ps -aux | grep pinentry

show that gpg-agent trying to use pinentry-gnome3

When i generate pair of keys in the command line, but after closing aplication window (gpgfrontend), everything works correctly. After showing the window to enter the password I am doing the command again:
ps -aux | grep pinentry

show that gpg-agent trying to use pinentry-gtk

I think there is here problem that gpgfrontend trying use incorrect pinentry.
How i can setting another pinenty to use by gpgfrontend. I trying setting variable environment:

export PINENTRY=/usr/share/pinentry-gtk

but it dosn't work. I don't know if this is a configuration error or a program error.
Could you advise something, tell you how to fix it ?.

Thanks for reporting this. The issue comes from a missing comma in the DecidePinentry() function, which makes pinentry-gtk or pinentry-qt not detected.

GpgFrontend/src/core/utils/GpgUtils.cpp

Lines 468 to 506 in 60f04a8

	auto GF_CORE_EXPORT DecidePinentry() -> QString {
	#ifdef Q_OS_LINUX
	QStringList preferred_list = {"pinentry-gnome3",
	"pinentry-qt"
	"pinentry-gtk2"};
	QStringList search_paths = {"/bin", "/usr/bin", "/usr/local/bin"};
	#elif defined(Q_OS_MACOS)
	QStringList preferred_list = {"pinentry-mac", "pinentry-qt"};
	QStringList search_paths = {"/opt/homebrew/bin", "/usr/local/bin"};
	#else
	QStringList preferred_list = {"pinentry-qt"};
	QStringList search_paths = {};
	#endif
	if (IsFlatpakENV()) {
	LOG_D() << "set flatpak pinentry to /app/bin/pinentry-qt";
	return "/app/bin/pinentry-qt";
	}
	for (const QString& name : preferred_list) {
	auto path = QStandardPaths::findExecutable(name);
	if (!path.isEmpty()) {
	LOG_D() << "find pinentry path: " << path;
	return path;
	}
	}
	if (search_paths.isEmpty()) return {};
	for (const QString& name : preferred_list) {
	auto path = QStandardPaths::findExecutable(name, search_paths);
	if (!path.isEmpty()) {
	LOG_D() << "find pinentry path by search path: " << path;
	return path;
	}
	}
	return {};
	}

GpgFrontend launches its own gpg-agent and enforces its own pinentry path, so external environment variables will not help here. There isn’t really a perfect temporary workaround in this case. I will fix this in the code within the next few days.
