dist-upgrade from ubuntu 20.04 to 22.04

Missing APT packages to install ``` sudo apt install libapache2-mod-fcgid php8.1-bcmath php8.1-cli php8.1-common php8.1-curl php8.1-fpm php8.1-gd php8.1-ldap php8.1-mbstring php8.1-mysql php8.1-opcache php8.1-pgsql php8.1-soap php8.1-xml php8.1-zip ```

PHP 8.1 FPM enabled in Apache2

a2enmod proxy_fcgi setenvif
a2enconf php8.1-fpm
sudo service apache2 restart

Modify Apache i-doit.conf

sudo nano /etc/apache2/sites-available/i-doit.conf

Change the PHP version from 7.4 to 8.1 in the following line

SetHandler "proxy:unix:/var/run/php/php8.1-fpm.sock|fcgi://localhost/"

Restart apache2

sudo service apache2 restart

Copy PHP i-doit.ini to the new PHP folder

sudo cp -i /etc/php/7.4/mods-available/i-doit.ini /etc/php/8.1/mods-available/i-doit.ini

Check the new i-doit.ini to see if the max_input_vars and post_max_size values are correct, otherwise change them

sudo cat /etc/php/8.1/mods-available/i-doit.ini | grep max_input_vars
sudo cat /etc/php/8.1/mods-available/i-doit.ini | grep post_max_size

Modify the variables in all three php.ini files

sudo find / -name -f php.ini

• max_input_vars = 10000
• post_max_size = 256MB

Activate the new PHP version 8.1

sudo update-alternatives --set php /usr/bin/php8.1

Restart PHP 8.1

sudo service php8.1-fpm restart

Restart Apache

sudo service apache2 restart

General update from php 7.4 to php 8.x
