master.cf-issue while install-process + things I noticed

**biologist** · Dec 24th 2018

Old:

Ubuntu 16.04 LTS / iMSCP Build: 20170908 (1.5.1)

New:

Ubuntu 18.04 LTS / iMSCP Build: 2018120800 (1.5.3)

1)

In order to test the installation-process of the current i-mscp-version, I cloned by webserver's content into a local VM. After a number of install-steps, the installer stopped because of:

Code

[ERROR] Servers::mta::postfix::postconf: postconf: fatal: file /etc/postfix/master.cf: line 48: bad field count

So I had a closer look on what happened.

master.cf:

Code

spfcheck unix - n n - 0 spawn
user=policyd-spf argv=/usr/sbin/postfix-policyd-spf-perl

(Second one is line 48).

Running postconf manually led to the same problem. It turned out that missing whitespaces led to this problem.

So I looked up where these two lines come from - a postfix listener:

Code

'spfcheck unix - n n - 0 spawn',
'user=policyd-spf argv=/usr/sbin/postfix-policyd-spf-perl'

Obvisously I forgot to intruduce whitespaces in the second line. So I did now but again, postconf complained. Finally, after deleting those two lines from config as well as listener, it worked.

I'm not sure if I did something wrong or if imscp "forgets" to add the whitespaces I introduced.

2)

However, I'm having another question:

I'm using phpswitcher along with two 5.6-versions and one 7.1. It turned out that 5.6 was deactivated because of:

Quote

`/opt/phpswitcher/20170817/php5.6/bin/php-cgi' doesn't looks like a PHP FastCGI binary

To be honest, I don't know whats wrong with it. So my question is: what could be the missing criteria?

3)

At last, after upgrading from 16.04 to 18.04, I started the imscp-installer. This didn't work because of

Quote

curl : Depends: libcurl4 (= 7.58.0-2ubuntu3.5) but it is not going to be installed

After running "apt-get install curl" a lot of packages were installed (PHP 7.1 e.g.). But again, the next try led into:

Quote

The following packages have unmet dependencies:

apache2 : Depends: apache2-utils (= 2.4.29-1ubuntu4.5)

"apt list --upgradable" showed several packages to be installed, so I did.

php7.2-common php7.2-soap

Unfortunately next try to start installation led into:

E: Unable to correct problems, you have held broken packages.

So it turned out, that apache has not been installed because of dependency-problems.

Finally I ended up with

This worked.

Well, but in the end, I don't know where these dependency-problems came from. Is this maybe because of using

deb http://ppa.launchpad.net/ondrej/php/ubuntu xenial main

deb-src http://ppa.launchpad.net/ondrej/php/ubuntu xenial main

?

I just mention all that stuff, because phpswitcher introduced this repository.

I'm sorry to put three things into a single topic, but I'm not sure if they're really related to imscp or jsut because I made something wrong. So I don't wanted to open 3 threads in a row.

Thanks in advance.

One subject, one thread please.

Regarding your postfix listener, best would be to post it there.

Regarding the APT dependency problem this is not due to i-MSCP. I think you've done partial upgrade. Note that the PPA repository is added by the i-MSCP installer (expected). This has nothing to do with the PhpSwitcher plugin but yes, in current version of the PhpSwitcher plugin, there is dependencies problems.

**biologist** · Dec 24th 2018

Hmm, weird. To update Ubuntu, I ran:

apt install update-manager-core

do-release-upgrade

However, I've been creating a snapshot before update. Maybe I'm gonna run the update again and try to keep track on what happens (especially) with Apache2.

Don't know, if I got you right. Does that mean the current plugin is not compatible with 18.04? But yes, indeed... I forgot 7.1-repository was introduced by imscp directly.

Here's my listener. As already written: in the very beginning the indention of the last maser.cf-line was missing. I added it but unfortunately, this didn't work.

Thanks for your help and merry xmas!

Did some further tests and as it seems, PHP 7.1 is the problem. I ran "apt remove php7.1*". It produced some warnings and finally the installation process breaked because of imscp complaining, but the number of packages to be installed was > 700 while previously at around 500-something.

However, as 7.2 is part of 18.04lts, maybe it makes sense to temporarily remove PHP 7.1 and "telling" imscp to use 5.6 instead. After upgrading to 18.04 php 7.2 would be available so I'd tell imscp later to with 7.2 while 7.1 could be provided using phpswitcher. If there's a better solution, please tell me.

So I tried to change php-Configuration using

Code

imscp-reconfigure -r php -d

but I finally ran into

Subsequently I downloaded the current release but it immediately hangs forever at:

Quote

[INFO] Satisfying prerequisites... Please wait.

So: What is the suggested way to get rid of these dependency problems?

**Nuxwin** · Dec 25th 2018

run the installer instead (of latest 1.5.3 build): perl imscp-autoinstall -dr php

**biologist** · Dec 25th 2018

Hmm, shows a little progress, but stops with

Quote

[ERROR] iMSCP::Stepper::_callback: The following PHP modules are not installed or not enabled: apc, apcu

[ERROR] autoinstaller::Functions::build: An error occurred while performing build steps

But, in fact, it is installed:

root@lsrv8 /var/log/imscp # apt install php-apcu

Reading package lists... Done

Building dependency tree

Reading state information... Done

php-apcu is already the newest version (5.1.16+4.0.11-1+ubuntu16.04.1+deb.sury.org+1).

I ran "phpenmod apcu" but the result is the same

BTW: Thnx for your quick answer.

biologist, I don't know what you have done... Really... I'm currently under bionic and I've not such issue... Can I access the server?

**biologist** · Dec 25th 2018

Fixed through online-support by Nuxwin.

Thanks a lot!

You're welcome.
