Установка qt5 зависает при установке бездисплейный с xvfb-управляемым через соединение SSH с помощью официального .run установщика

У меня есть проблема с попыткой установить QT. Я следую инструкциям из http://splash.readthedocs.io/en/latest/install.html и из их источника provision.sh Я использую эти команды, чтобы попытаться установить QT5 с помощью офлайнового установщика, предоставленного на спокойном веб-сайте

curl -L -o /downloads/qt-installer.run \
               http://download.qt.io/official_releases/qt/5.9/5.9.1/qt-opensource-linux-x64-5.9.1.run && \
    chmod +x /downloads/qt-installer.run && \
    xvfb-run /downloads/qt-installer.run

Так как я пытаюсь установить через удаленный компьютер, я должен использовать xvfb-управляемый, чтобы попытаться установить его бездисплейный, однако когда я работаю xvfb-run /downloads/qt-installer.run моя командная строка просто зависает после того, как у некоторых подсказок и меня нет подсказки, что они имеют в виду и с часов поиска с помощью Google, я, может казаться, не переношу голову вокруг того, что я, как предполагается, делаю или что я делаю неправильно.

Вот то, что это производит:

xvfb-run /downloads/qt-installer.run
