试图配置Xvfb无头地运行Firefox

Question

我正在按照本教程来配置Xvfb无头地运行firefox.

http://www.alittlemadness.com/2008/03/05/running-selenium-headless/

我现在在docker镜像(ubuntu:latest)中运行这些命令,看看我是否可以在创建容器之前正确设置我的配置.

我正在坚持运行这个命令:

Xvfb :99 -ac

运行命令后出现这些错误:

我找到了一个谷歌搜索的博客,在这里提到这些错误:

http://veeraramkumar.blogspot.com/

我运行了这些命令:

aptitude install x11-xkb-utils
aptitude install xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic
aptitude install xserver-xorg-core

但是命令:

aptitude install xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic

给出了这个错误:

No candidate version found for xfonts-100dpi
No candidate version found for xfonts-75dpi
No candidate version found for xfonts-cyrillic
No candidate version found for xfonts-100dpi
No candidate version found for xfonts-75dpi
No candidate version found for xfonts-cyrillic
The following NEW packages will be installed:
  xfonts-scalable

然后它成功安装了xfonts-scalable.现在当我重新运行命令时:

Xvfb :99 -ac

我只收到这些错误(最多5个错误):

[dix] Could not init font path element /usr/share/fonts/X11/cyrillic, removing from list!
[dix] Could not init font path element /usr/share/fonts/X11/100dpi/:unscaled, removing from list!

[dix] Could not init font path element /usr/share/fonts/X11/100dpi, removing from list!
[dix] Could not init font path element /usr/share/fonts/X11/75dpi, removing from list!

我尝试使用apt-get来查找软件包xfonts-100dpi xfonts-75dpi xfonts-cyrillic,但它也说明软件包也没有安装候选者.我需要安装哪些正确的软件包才能正确配置Xvfb以无头地运行firefox？或者我还应该做些什么呢？

谢谢.

在深入研究其他类似的问题之后,一旦我重新启动了我的ubuntu docker镜像,我就能够让Xvfb正确使用以下命令.

apt-get update

apt-get install -y xorg xvfb firefox dbus-x11 xfonts-100dpi xfonts-75dpi xfonts-cyrillic

以前我在更新后错过了xorg和dbus-x11软件包.
