Updating Caddy to PHP 7.2

This was wonderfully easy.

sudo apt update && sudo apt dist-upgrade -y && sudo apt autoremove -y && sudo apt autoclean
sudo apt install php7.2-cli php7.2-common php7.2-fpm php7.2-json php7.2-mysql php7.2-opcache php7.2-readline

Update Caddyfile:

sudo vim /etc/caddy/Caddyfile
www.yawnbox.com {
        redir https://yawnbox.com{uri}
        }

yawnbox.com {
        root /var/www/yawnbox/
        log stdout
        errors stderr

header / {
        Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';"
        Expect-CT "enforce; max-age=7073887;"
        Referrer-Policy "strict-origin, strict-origin-when-cross-origin"
        Strict-Transport-Security "max-age=15768000; includeSubDomains; preload"
        X-XSS-Protection "1; mode=block"
        X-Content-Type-Options "nosniff"
        X-Frame-Options "DENY"
        }

fastcgi / /var/run/php/php7.2-fpm.sock {
        ext .php
        split .php
        index index.php
        }

rewrite / {
        to {path} {path}/ /index.php?{query}
        }

tls {
        protocols tls1.2
        curves p384
        key_type p384
        }
sudo service caddy restart
sudo apt remove php-mysql php7.1-cli php7.1-common php7.1-fpm php7.1-json php7.1-mysql php7.1-opcache php7.1-readline
