Erreur lancement Appache2 = pb de php7.4 et 8

 sudo apt install php8.1-cli php8.1-common php8.1-imap php8.1-redis php8.1-xml php8.1-zip php8.1-mbstring

  sudo a2dismod php7.4 
  sudo a2enmod php8.1 
  

(This is php ver. you have after upgrade. Please verify the exact version by looking into /etc/apache2/mods-available folder. In my case I could see the latest ver. of php8.1 so did accordingly mentioned in this command)

  systemctl restart apache2
  sudo apachectl configtest

sudo apt update && sudo apt upgrade
sudo apt install apache2 apache2-utils mariadb-server mariadb-client -y
sudo apt install php libapache2-mod-php php-mysql php-common php-cli php-common php-json php-opcache php-readline -y
sudo apt install php-fpm php-cgi php-curl php-gd php-intl php-mbstring php-xml php-zip -y
