Postfix is now set up with a default configuration.  If you need to make
changes, edit
/etc/postfix/main.cf (and others) as needed.  To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

我尝试了 aptitude purge、remove、autoclean 和所有 dpkg 选项（configure、remove、purge），但都无济于事。/etc/mailname 存在（0644 root:root），内容为 ***.net（从 中获取hostname）。我做错了什么？

答案1

可以尝试以下操作：

  • 是不是你/etc/mailname在其他进程中打开了？用 检查一下lsof | grep mailname。
  • 如果我没记错的话，我曾经遇到过类似的错误，这是由于文件系统损坏造成的，所以也许fsck在你的系统上运行了一个。

答案2

您可以尝试将机器名称放入 /etc/mailname 中吗？类似 machinename.local 的内容应该足够了（只要它能解析）。如果需要，请将其添加到 /etc/hosts。

答案3

这让我想起了不久前 postgreSQL 的一个 aptitude 错误。如果您认为一切都应该正常，请尝试使用备用包管理器。也许是包管理器的问题。这解决了我不久前使用 postgreSQL 时遇到的问题。

答案4

dpkg 能否检查所有文件是否存在错误权限、所有者/组、selinux 上下文等？如果可以 - 检查...
