When running the install script on a fresh Ubuntu 22.04, I get the following error upon configuring Postfix in phase 4 (excerpt from log file):

@fuggi,

Is this a fresh install on a freshly installed OS? Are you using the Virtualmin installer?

Joe · November 12, 2024, 4:47pm

That doesn’t look like a freshly installed OS.

ID10T · November 12, 2024, 4:51pm

Maybe not a ‘minimal install’?
help.ubuntu.com/community/Installation/MinimalCD

Joe · November 12, 2024, 4:54pm

It doesn’t have to be minimal. It just needs to be freshly installed. I prefer minimal just because there’s a lot of junk in a bigger install, but we have tested on a regular non-minimal installation, as well. (Though it’s been a long time since we were testing new installs on 22.04. @fuggi we generally recommend you use the latest supported version of your preferred OS, which would be 24.04. That will provide a longer lifecycle, and will be the version we’re currently doing most of our testing on.)

fuggi · November 12, 2024, 5:12pm

It is a fresh install on a VPS as delivered by the provider, but not a minimal.

I’ve just tried it on 24.04.01, but got the same error.

tpnsolutions · November 12, 2024, 5:25pm

@fuggi,

Where are you downloading the installer from?

Joe · November 12, 2024, 5:30pm

OK, I assume they’ve got custom repositories configured and they’re broken. Maybe choose a better provider.

The issue actually would have been earlier in the log, probably during installation of the packages, and not during configuration. The configuration step looks like it’s failing because some stuff just isn’t installed. We don’t provide the missing packages, they’d come from the OS repos, and if your provider has custom repos that don’t work, that would explain it.

Joe · November 12, 2024, 5:30pm

I don’t think it has anything to do with the installer.

fuggi · November 12, 2024, 5:30pm

Directly from the Virtualmin website by running

sh -c "$(curl -fsSL https://software.virtualmin.com/gpl/scripts/virtualmin-install.sh)" -- --bundle LAMP

Note, I’m root on that VPS.

tpnsolutions · November 12, 2024, 5:32pm

@fuggi,

Before running the installer, did you run:

sudo apt update

Were there any errors presented during this step?

*** Perhaps send us a screenshot of what this step produces ***

fuggi · November 12, 2024, 5:35pm

Doesn’t look like custom repos to me IMHO:

root@server:~# grep ^ /etc/apt/sources.list /etc/apt/sources.list.d/*

tpnsolutions:

*** Perhaps send us a screenshot of what this step produces ***

Yes, I did and yes, there was a 404 error regarding the Virtuozzo repo:

Err:13 https://repo.virtuozzo.com/ctpreset/deb  Packages
  404  Not Found [IP: 46.231.178.114 443]

I guess we are getting closer to the root cause now, aren’t we?

tpnsolutions · November 12, 2024, 5:41pm

@fuggi,

Was that repo installed during VPS creation or afterwards?

fuggi · November 12, 2024, 5:41pm

@tpnsolutions
During VPS creation.

tpnsolutions · November 12, 2024, 5:48pm

@fuggi,

While that repo doesn’t seem broken from here (resolves to a diff IP from my computer – likely localized CDN)… Try disabling the repo, then run the installer to see if you can get it working…

== DISABLE REPO ==

Simply rename:

to

then re-run:

jimr1 · November 12, 2024, 5:51pm

Dont forget this is ubuntu 24.04 and the list file may have been replaced with a .sources file so if that file exists you may have to move that, but if the .list file exists you are 100% correct

tpnsolutions · November 12, 2024, 5:54pm

@jimr1,

Recommendation ATM is based on output posted from command:

Noted above

fuggi · November 12, 2024, 5:56pm

@jimr1
The apt-get update command worked without any error after disabling the list file. So I assume it did the trick.

@tpnsolutions
However, I seem to run into the same error again. But I noticed something in the standard output (not log file) which I also recall from my first attempt:
