 Here are some of the Linux hints and documentation that seems to be woefully lacking or just mis-leading on the greater wider Internet.
+===== Installing HWE kernel =====
+This example is for Ubuntu 22.04 but the same principle applies to other releases too.
 ===== Installing latest PHP on Ubuntu =====

 Easy, install the latest php which, at time of writing, is 7.4.
+We need to add Ondre Sury's PPA repository which has the latest php builds. Ondre also recommends installing his PPA of apache2, so we'll add that as well.
+<code>
+philip@host:~$ sudo -s
+root@host:~# add-apt-repository ppa:ondrej/php
+root@host:~# add-apt-repository ppa:ondrej/apache2
+root@host:~# apt update
+</code>
+This will update the database to the latest packages available. And then we simply do:
+<code>
+root@host:~# apt upgrade
+</code>
+which will update php and apache2 to the latest versions plus do all the needful with enabling modules etc etc.
+Once installed check that it is working by running ''php -v''. You should see output like this:
+<code>
+philip@host:~$ php -v
+PHP 7.4.12 (cli) (built: Oct 31 2020 17:04:09) ( NTS )
+Copyright (c) The PHP Group
+Zend Engine v3.4.0, Copyright (c) Zend Technologies
+    with Zend OPcache v7.4.12, Copyright (c), by Zend Technologies
+</code>
+It is also worth checking that ''/etc/php/7.4/apache2/php.ini'' and ''/etc/php/7.4/cli/php.ini'' have the settings you expect. Compare with your previous version of php. Most commonly, the timezone value will need to be set different from UTC0/GMT.
