When installing 24.04 postfix is now part of the required packages. In a non-interactive installation, this can cause problems as the default values try to populate $myhostname using dns. To get a working installation, I used debconf-get-selections | grep postfix after installing postfix with the "no configuration" option.
postfix postfix/main_mailer_type select No configuration postfix postfix/mailbox_limit string 0 postfix postfix/procmail boolean postfix postfix/main_cf_conversion_warning boolean true postfix postfix/compat_conversion_warning boolean true postfix postfix/mailname string /etc/mailname postfix postfix/recipient_delim string + postfix postfix/not_configured error postfix postfix/root_address string postfix postfix/relayhost string postfix postfix/bad_recipient_delimiter error postfix postfix/dynamicmaps_conversion_warning boolean postfix postfix/rfc1035_violation boolean false postfix postfix/destinations string postfix postfix/newaliases boolean false postfix postfix/protocols select postfix postfix/chattr boolean false postfix postfix/mynetworks string 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 This ensures no aliases are created for postfix and hence the installation goes through.
