因此我尝试安装 dovecot-common、dovecot-imapd 和 dovecot-pop3d。但是，我不断收到以下错误消息：
Setting up dovecot-imapd (1:2.1.7-7+deb7u1) ...
Creating config file /etc/dovecot/conf.d/20-imap.conf with new version
cp: cannot create regular file `/etc/dovecot/conf.d/20-imap.conf': No such file or directory
dpkg: error processing dovecot-imapd (--configure):
subprocess installed post-installation script returned error exit status 1
Setting up dovecot-pop3d (1:2.1.7-7+deb7u1) ...
Creating config file /etc/dovecot/conf.d/20-pop3.conf with new version
cp: cannot create regular file `/etc/dovecot/conf.d/20-pop3.conf': No such file or directory
dpkg: error processing dovecot-pop3d (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
dovecot-imapd
dovecot-pop3d
E: Sub-process /usr/bin/dpkg returned an error code (1)
我检查了 /etc/ 文件夹，但似乎甚至没有创建 /etc/dovecot 文件夹，因为它根本不存在。
请有人帮帮我……

既然软件包无法创建目录，为什么不尝试创建 /etc/dovecot 呢？或者最终是 /etc/dovecot/conf.d/ 软件包管理中可能存在一些不 100% 正确的内容，因此无法创建目录。如果您手动创建它们，在最坏的情况下，它可能会提到目录已经存在。
