我正在按照本教程来配置Xvfb无头地运行firefox.

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：

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!

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.
