System updates kill box

Good afternoon all.

I’m running Ubuntu Linux 18.04.3. I’ve got a number of updates to perform on the system and when I do, I am presented with a number of upgrade choices. How should I answer them? I’ve tried a number of different combinations but always end up with a non-working system.

During the upgrade I’m asked:

  1. Configure database for opendmarc
  2. To select the type of mail configuration for Postfix.
  3. For each of the following I’m told:
    Modified (by you or by a script) since installation. Package distributor has shipped an updated version.
    And offered the choice of A. install the package maintainer’s version or B. keep your currently-installed version:
    Configuration file ‘/etc/systemd/resolved.conf’
    Configuration file ‘/etc/sysctl.conf’
    Configuration file ‘/etc/nsd/nsd.conf’
    Configuration file ‘/etc/default/spamassassin’
    Configuration file ‘/etc/opendmarc.conf’
    Configuration file ‘/etc/bind/named.conf.options’
    configuration file /etc/dovecot/dovecot-sql.conf.ext
    configuration file /etc/dovecot/conf.d/10-logging.conf
    configuration file /etc/dovecot/conf.d/10-mail.conf
    configuration file /etc/dovecot/conf.d/10-master.conf
    configuration file /etc/dovecot/conf.d/10-ssl.conf
    configuration file /etc/dovecot/conf.d/15-lda.conf
    configuration file /etc/dovecot/conf.d/20-imap.conf
    configuration file /etc/dovecot/conf.d/20-pop3.conf
    configuration file /etc/ssh/sshd_config

What’s the best approach to this?

Thanks for reading and any suggestions you may have.

But seriously I’d let unattended-upgrades do it’s magic over night if it were me.

After running the updates, run the command sudo mailinabox

Yeah, I tried, but it errored out right away. I was pretty frustrated and didn’t write down the error message.
I image the VM before trying the upgrade, I’ll try it again both ways; answering “Yes” to everything and answering “No” to everything. I’ll update with the results.

What upgrade???

Again you have not made it clear why you are not allowing unattended-upgrades to do its job.

Thanks, I’ll try unattended-upgrades.
