Problem adding more PHP versions (8.x) on older Ubuntu 18.04

Good day,

I upgraded (Ubuntu 18.04.6 LTS (Bionic Beaver)) ISPConfig 3.2.10p1 to the latest ISPConfig 3.2.11p1

I presently have php5.6. php7.3 and php7.4. Where php7.2 seems to be the base PHP install with this older OS.

root@host:~# php -v
PHP 7.2.24-0ubuntu0.18.04.17 (cli) (built: Feb 23 2023 13:29:25) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.2.24-0ubuntu0.18.04.17, Copyright (c) 1999-2018, by Zend Technologies​

In the past I've installed the other versions this way:

root@host:~# history |grep php
...
197 apt-get -y install php7.4 php7.4-common php7.4-fpm php7.4-gd php7.4-mysql php7.4-imap php7.4-cli php7.4-cgi php-pear php7.4-curl php7.4-intl php7.4-pspell php7.4-sqlite3 php7.4-tidy php7.4-xmlrpc php7.4-xsl php-memcache php-imagick php-gettext php7.4-zipphp7.4-mbstring php7.4-soap php7.4-common php7.4-opcache php7.4-mysql
199 update-alternatives --config php
200 update-alternatives --config php-cgi​

This time it didn't work for 8.x - My client needs 8.1, 8.2 later).

I followed these 2 similar procedures:
https://forum.howtoforge.com/threads/install-php-8-1.88098/
https://www.howtoforge.com/ispconfig-php-ubuntu/
​

Everything goes well with:

add-apt-repository -y ppandrej/php (I even tried apt-get install software-properties-common gnupg2 -y)
apt-get update
apt-get upgrade
​

But when I run a simple command it doesn't work (same for 8.2 and 8.3)?

root@host:~# apt-get install php8.1 php8.1-fpm php8.1-cli -y

Any hints on how I can get this fixed? Looking for a quick win as the customer wants to start testing this Friday.

I sure hope it's not an Ubuntu 18.04.6 issue. I only seem to see Jammy (22.04) and Focal (20.04) on the ondrej sury site.

If it is, do you have another Repo you could recommend?
Or would you have a Ubuntu style procedure to compile it like this I used to use back in the days:

I understand it might be time to set up a new VM. There is no need for php5.6 anymore and the site is moving from 7.4 to 8.1.
I even read this online : Ubuntu 18.04 end of life reached on May 31, 2023.


I thank you in advance for your excellent support as I know this is more an OS than ISPConfig issue.

You would not reccomend Building it either?
Something like this?
