Requesting Updated Ubuntu 20.04 LTS Installation Documentation

I am requesting that the documentation be updated to provide the correct prerequisite packages required for Ubuntu 20.04 LTS. 

At first I thought the best list of prerequisites would be in the 'How To Install or Upgrade Open-AudIT (Linux)' page (2019-03-12), but more recent prerequisite information is provided in the 'Server Requirements' page (2020-12-11). 

I also noticed that the release notes for OA v3.3.1 mention moving to mariadb-server for Ubuntu 20.04 instead of mysql-server, yet this "apt-get install" line is still using mysql-server instead of mariadb-server.  I looked through all the other release notes from v3.3.2 up to v4.0.1, but don't see any mention of switching back to mysql-server.  So should this "apt-get install" line be using mariadb-server?

The prerequisites provided by the Server Requirements page for Ubuntu 16.06+ are as follows:

$ sudo apt-get install mysql-server apache2 apache2-utils libapache2-mod-php openssh-client php php-ldap php-mbstring php-mcrypt php-mysql php-snmp php-simplexml nmap zip wget curl sshpass screen smbclient logrotate libtime-modules-perl ipmitool rrdtool librrd4 libpng12-0

That command attempts to perform the install, but conks out early because packages cannot be found:
