[Bug 763923] Re: package postfix 2.8.2-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 75

[Andres Rodriguez]

Hi there,

Thank you for taking the time to report bugs and trying to make Ubuntu
Server better.

According to the information you have provided, it seems that the reason
why it failed to upgrade is because one of the parameters in the config
file does not take multiple values:

newaliases: fatal: myorigin parameter setting must not contain multiple
values: P.E. Wigboldus

So, this means that you would have to change the parameter accordingly
as it only takes one single value. Once you change it, you should be
able to do the following to complete the installation:

sudo dpkg --configure -a

Please, let us know how it goes.

Cheers,

** Changed in: postfix (Ubuntu)
       Status: New => Incomplete
