Failed to start The PHP 8.0 FastCGI Process when update to php8.0-CodePudding

I am trying to update from php7.4 to php8.0

I applied the following steps

sudo apt update
sudo apt upgrade

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

apt-get install php8.0 php8.0-bz2 php8.0-cgi php8.0-cli php8.0-common php8.0-curl php8.0-fpm php8.0-gd php8.0-intl php8.0-mbstring php8.0-mysql php8.0-opcache php8.0-pspell php8.0-readline php8.0-xml php8.0-zip php8.0-imagick

But I got the error

Knowing that there is no "php-fpm.conf" file in "/etc/php/8.0/fpm/"

CodePudding user response：

By logs I see somehow You've lost config file: /etc/php/8.0/fpm/php-fpm.conf

So I found one in my server and put to Gist.

Need to put that on Your server.

In terminal:

cd ~

wget https://gist.githubusercontent.com/num8er/6cf84e1a544cc7751d3f6974d10b10a0/raw/d9bf057d3acc297d79235b282319f29f60a4301b/php-fpm.conf

sudo mv php-fpm.conf /etc/php/8.0/fpm/php-fpm.conf

sudo systemctl restart php8.0-fpm

if You still have issues, uninstall all php stuff, and install again:

apt purge -y php7.4*

apt purge -y php8.0*

apt-get install php8.0 php8.0-fpm php8.0-dev php8.0-bz2 php8.0-cgi php8.0-cli php8.0-common php8.0-curl php8.0-gd php8.0-intl php8.0-mbstring php8.0-mysql php8.0-mysqli php8.0-pdo php8.0-opcache php8.0-pspell php8.0-readline php8.0-xml php8.0-zip php8.0-imagick
