package postfix 2.7.0-1 failed to install/upgrade: 子程序 installed post-installation script 傳回了錯誤退出狀態 75

Error from log:

Running newaliases

dpkg：在處理 postfix (--configure) 時發生錯誤：
 子程序 installed post-installation script 傳回了錯誤退出狀態 75

Thank you for taking the time to report this bug and helping to make Ubuntu better.

It looks like your postfix main configuration file (/etc/postfix/main.cf) has a invalid value (04) for the mydomain parameter; this parameter should contain the internet domain name for this system - 04 is not a valid entry (see man 5 postconf for more information).

Please can you update the configuration file to have a valid internet domain name for this entry and then run the following command:

   sudo dpkg-reconfigure postfix

This should then complete the installation.

Oh - and please update this bug report if this resolves your issue!

Really thank you very much for any suggestion, I will follow the command you
pointing.
And, thank you again. If get any new report I will update as you say.

Thank you, James~
It is no error message again~ I hope it is done [?]
I share my step about some solutions of this bug.

1. check the /etc/postfix/main.cf
2. search the /etc/hosts and /etc/hostname, comparing those infomation
 with /etc/postfix/main.cf [myhostname = ?] parameter.
3. I change the myhostname parameter to be the same with /etc/hostname.
4. apt-get upgrade --force-yes (little danger :P)
    or sudo dpkg-reconfigure postfix

This is not a package bug. The invalid hostname checks are there by design and will stay.

Thank your information~
