That’s where PHPenv comes in. It’s an excellent tool for local development—and even for UAT servers.
To demonstrate how to use different PHP versions side by side, I’ll first install WordPress on Ubuntu 20.04 using Ansible. After that, I’ll set up PHPenv and switch to PHP 8.2.5 using pfm.

Upgrading Nagios core from source was remove from official documentation, so I leave that here. Change nagios-4.5.11 with the version you want to upgrade to.
sudo systemctl stop nagios.service
cd /tmp/
sudo rm -rf nagioscore*
wget -O nagioscore.tar.gz https://github.com/NagiosEnterprises/nagioscore/archive/nagios-4.5.11.tar.gz
tar xzf nagioscore.tar.gz
ll
cd nagioscore-nagios-4.5.11/
sudo ./configure --with-httpd-conf=/etc/apache2/sites-enabled
sudo make all
sudo make install
sudo make install-daemoninit
sudo systemctl start nagios.service
sudo systemctl status nagios.service
