我最近一直在尝试安装发送邮件（我以前一直在使用带有 mailutils 的 postfix），第一次尝试安装它花了一整晚的时间，然后我早上取消了它并说：
dpkg: error processing package sendmail-bin (--configure):
subprocess installed post-installation script was interrupted
dpkg: dependency problems prevent configuration of sensible-mda:
sensible-mda depends on sendmail-bin | mail-transport-agent; however:
Package sendmail-bin is not configured yet.
Package mail-transport-agent is not installed.
Package sendmail-bin which provides mail-transport-agent is not configured yet.
Package postfix which provides mail-transport-agent is not installed.
dpkg: error processing package sensible-mda (--configure):

dpkg: dependency problems prevent configuration of sendmail:
sendmail depends on sendmail-bin; however:
Package sendmail-bin is not configured yet.
sendmail depends on sensible-mda; however:

Errors were encountered while processing:

使用dpkg --configure -a并不能解决问题。它只会带来相同的错误。
