Hi ydheur, there seems to be a conflict with your system setup and the constraints postfix has on install. It tries to set up a basic configuration base on your hostname.
That is according to the logs: Hostname: YYY14.04 The scripts ahve to derive from there (no better source of that info) so they do. But a dot in a hostname is splitting a fqdn so the actual main host is considered to be "04". That in turn is invalid and lets the configuration fail, here from your log: newaliases: warning: valid_hostname: numeric hostname: 04 newaliases: fatal: file /etc/postfix/main.cf: parameter mydomain: bad parameter value: 04 You have to adapt your hostname to be compatible or setup and configure postfix on your own not relying on the scripts that run on install. I'd recommend the former -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1711432 Title: package postfix 3.1.0-3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 75 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1711432/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
