我正在尝试从Source安装CKAN，并已按照此处的说明通过设置Apache来进行生产部署： https://docs.ckan.org/en/2.8/maintaining/installing/install-from-source.html https://docs.ckan.org/en/2.8/maintaining/installing/deployment.html
在安装结束时情况很好，并且粘贴程序可以在5000端口上为CKAN提供服务。
然后通过部署工作，一切似乎一直进行到最后返回403错误为止。日志详细说明了符号链接不起作用。因此（这是我最有可能弄糟的地方），我取消了符号链接并使它们全部成为硬链接。这解决了符号链接问题，并在日志中出现此错误：

我已经遍历了在堆栈溢出和其他地方找到的各种解决方案，这些解决方案实际上等于找到具有错误权限的文件夹或文件。我也尝试过在这里找到WSGIPythonHome修复程序： CKAN distribution not found error while trying to serve CKAN from apache
现在我不能再使用粘贴程序，错误再次出现：
-bash: /usr/lib/ckan/default/bin/paster: Permission denied
这是我在全新安装Ubuntu之前的最后一次尝试，然后再次从头开始。任何意见，将不胜感激。甚至还有一些建议，可以解决此类问题。
