Postfix error on fresh install about virtualmin-install

[iliajie]

Hi,

It works for me.

What is the output of the following commands:

whereis postconf
whereis postfix
dpkg -l "postfix*"

Was it clean instance before you ran install.sh script? How did you install Virtualmin? Are there any errors in virtualmin-install.log file?

[anrikun]

HI @iliarostovtsev

I've managed to finish installation by reconfiguring postfix manually but installing this way might be risky this way.
So I've decided to reinstall OS completely and will run the commands you've suggested.
I'll let know what results I get.

[iliajie]

Before running install.sh script on a clean Ubuntu 20.04 LTS, make sure to run prior:

apt-get update
apt-get upgrade
reboot

[anrikun]

After fresh install:

apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get --purge autoremove

Changing hostname:

vi /etc/hostname
vi /etc/hosts
vi /etc/mailname
reboot

Installing:

wget http://software.virtualmin.com/gpl/scripts/install.sh
/bin/sh install.sh

In virtualmin-install.log, I see:
postconf: fatal: open /etc/postfix/main.cf: No such file or directory
newaliases: fatal: open /etc/postfix/main.cf: No such file or directory

/etc/postfix/main.cf is missing indeed.

[iliajie]

Would you get the same error if before running a clean install you change the host name as follows:

hostnamectl set-hostname fqdn

[anrikun]

Ok let's reinstall once more and give it a try :-)

[anrikun]

Nope! Exact same error :-(
I give up.

I manually created main.cf the way suggested by apt install --reinstall postfix:
cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf

Then ran again:
/bin/sh install.sh

That finished successfully this time.
Hope there's no side effect!

Now I have a problem with ClamAV:

Might be directly related to ClamAV server itself though...

[iliajie]

How exactly did you install Ubuntu 20.04 LTS? Is this clean and minimal ISO install or is it something else? Is it cloud based, if so, what is your provider? Did you install anything additionally before running install.sh script? It looks to me like not Virtualmin bug.

What is the output of:

cat /etc/os-release

[iliajie]

postconf: fatal: open /etc/postfix/main.cf: No such file or directory

This is not normal. By the way, earlier today I just did Virtualmin GPL installation with Ubuntu 20.04, and it wasn't the problem for me. It just worked flawlessly. Check virtualmin-install.log, perhaps Postfix package installation fails due to whatever reason .. lack of memory maybe?

[anrikun]

cat /etc/os-release

If you want my opinion, I don't think it's a Virtualmin bug either. The problem is that I don't have control on how OS is installed. I'm renting a dedicated server and the only thing I can decide is which OS I want, not how it is installed.

I've found something other strange in log:

postfix is ​​already the most recent version (3.4.13-0ubuntu1).
postfix changed to "manually installed".

That means that postfix might already have been present before running install?
