Issues with PHP5.6 and its additional modules installation on ubuntu 22.04

[Sura-AE]

I am trying to use MolProbity in docking (haddock2.4). PHP needed to be installed, and I downloaded version 5.6 on Ubuntu 22.04 using github ( #13 ) on Ubuntu 22.04. After following the instructions in the README, I found a couple of issues.

• dpkg: warning: unable to delete old directory '/var/lib/ubuntu-advantage': Directory not empty
  dpkg: warning: unable to delete old directory '/etc/ubuntu-advantage': Directory not empty

Also I am getting

Setting up snapd (2.63+22.04) ...
Installing new version of config file /etc/apparmor.d/usr.lib.snapd.snap-confine.real ...
snapd.failure.service is a disabled or a static unit not running, not starting it.
snapd.snap-repair.service is a disabled or a static unit not running, not starting it.
Failed to restart snapd.mounts-pre.target: Operation refused, unit snapd.mounts-pre.target may be requested by dependency only (it is configured to refuse manual start/stop).
See system logs and 'systemctl status snapd.mounts-pre.target' for details.
Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 142.

Afterwards, install additional PHP5.6 modules like MySQL, Curl, GD, OPCACHE, XML, etc using the command line below.

php5.6-xml libapache2-mod-php5.6 php5.6-cli

I am getting

Please can you help me to understand if I did something wrong and how can I deal with these issues?
