Hi @dwiady,

In order to install PHP 7.4, you need to download and store PPA repository in a file on your Debian Server + the GPG key. To do so, run the following commands:

sudo apt -y install lsb-release apt-transport-https ca-certificates 
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg

Once you’ve done this, add the repository:

echo "deb $(lsb_release -sc) main" | sudo tee /etc/apt/sources.list.d/php.list

Now Update your System and install your PHP version:

sudo apt update
sudo apt -y install php7.4
