我在 Ubuntu 12.04 服务器版上安装了 PacketFence，一切运行正常。我可以通过以下地址访问仪表板：https://(IP地址):1443没有问题。
将硬盘移到另一台机器并验证网络连接后，我再也无法访问仪表板了。摆弄了一会儿之后，我认为直接删除并重新安装会更快，因为我还没有完成配置过程。在sudo apt-get purge packetfence重新启动之后，我运行了sudo apt-get install packetfence（上次安装时已经添加了源和密钥）。完成后，我运行了sudo service packetfence start，它返回了packetfence: unrecognized service。我想我一定是在安装过程中忽略了某些错误消息，所以我再次运行了“sudo apt-get install packetfence”——下面您可以看到它返回的有问题的输出：

关于如何解决与 packetfence 相关的剩余软件包的问题，以便我可以从头开始重新安装它，有什么想法吗？
答案1
这个问题可以忽略。我通过以下操作解决了这个问题：
cd /var/lib/dpkg/info
sudo rm packetfence-redis-cache*
sudo dpkg --remove --force-remove-reinstreq packetfence-redis-cache
发出这些命令后，我能够使用 apt 成功重新安装 Packetfence。
