我正在运行 Ubuntu 16.04 LTS，最近调整了我的防火墙，以便 citadel 群件可以正常工作，但在设置和配置完成后，我执行了命令apt-get update，apt-get upgrade但似乎失败了。所以我想可能是服务器坏了，我继续安装建议的防病毒和垃圾邮件拦截器，但我得到了相同的代码行，如下所示：
root@pe-fw:/etc# apt-get install spamassassin

更新：当我尝试删除 citadel 时，我注意到代码行中有些奇怪的东西，我想这可能是原因，我注意到一些与 citadel 相关的词，经过一番研究和反复试验后，似乎 citadel 还没有完全消失，所以我试图追踪它的剩余部分并尝试删除它们，看看会发生什么
答案1
您正确地假设此问题与 citadel 有关。据我所知，“apt” 中的所有内容均正常运行，并且它警告您 citadel 安装存在问题。
我的建议：
sudo apt update
sudo apt remove spamassassin citadel-suite citadel-webcit
sudo apt autoclean
sudo apt autoremove
sudo apt dist-upgrade
上述五个命令应该会删除 spamassassin 和 citadel，然后清理不需要的软件包，最后更新机器上现有的软件。
完成后，如果您发现任何来自“apt”的错误，请告知我们。
只要上述操作完成后一切都干净了，您就可以重新安装 citadel，并检查安装后是否存在任何问题。
一旦您知道 citadel 安装没有问题，您就可以重新安装 spamassassin。
祝你好运。
答案2
在我注意到一些与 citadel 相关的文件名后，我查找并删除了它们。之后我重启了机器，运行了apt-get update && apt-get upgrade，现在 ubuntu 又正常工作了
