Не запускается отладка в QtCreator на Astra Linux

QtCreator 6.0.2, AstraLinux 1.7. Проект собирается через CMake, если это имеет значение. Отладка вроде настроена как надо, тип сборки стоит Debug, но при запуске в режиме отладки в правом нижнем углу плашка «Запуск отладчика» показывает красный цвет. В журнале такие записи:

Несколько раз писала ещё такие предупреждения:

warning: GDB: Failed to set controlling terminal: Inappropriate ioctl for device
warning: Could not trace the inferior process.Error: 
warning: ptrace: Operation not permitted

Как всё-таки запустить отладку в QtCreator?
