不确定为什么找不到supervisord配置文件或安装失败。我确实运行了aptitude update、aptitude upgrade，所以希望一切都是最新的:(
答案1
我刚刚遇到了同样的问题，所以我将说明发生此问题的原因。
我们使用 pip 将 Supervisor 安装到全局路径（而不是虚拟环境），这意味着我们运行的是最新版本。但是，从服务器维护的角度来看，这是不可取的，因此我们在 Apt 中切换了旧版本。
pip uninstall无法正确清理，在以下所有目录中留下脚本/日志：
- /usr/本地/bin/
- /usr/local/lib/python2.7/dist-packages/
- /tmp/
- /ETC/
我建议进行以下搜索并手动删除所有引用主管-3.0a12：
sudo find / -iname "*supervisor*"

有趣。这是一个目前未知的错误。安装时，您应该会收到不同的错误，因为此版本的 Ubuntu 中的主管目前已损坏。请参阅错误报告：https://bugs.launchpad.net/ubuntu/+source/supervisor/+bug/777862
答案3
管理员可能之前安装过，然后删除了但没有清除（因此配置文件没有被删除）。后来有人手动删除了配置文件。现在，当您重新安装时，它不会默认替换配置文件，因为 dpkg 永远不会覆盖您所做的配置更改，而删除配置文件被视为配置更改。您可以像这样专门告诉 dpkg 替换丢失的配置文件：
aptitude -o DPkg::Options::='--force-confmiss' reinstall supervisor
或者，您可以在安装之前清除包，表示您不想保存配置文件。
