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 ** Attachment added: "360.gif" https://bugs.launchpad.net/bugs/735239/+attachment/2064536/+files/360.gif -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to postfix in Ubuntu. https://bugs.launchpad.net/bugs/735239 Title: 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 -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
