[Bug 1703106] [NEW] package amavisd-new 1:2.10.1-2ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Public bug reported: It has to do with my variable $hostname that is not a FQDN but I don't have a FQDN because I don't have a mail server on my machine. Is there a way to get around this or do I have to desinstall amavis? Yes this is a bug because it happens all the time when there's updates. u
