I am trying to install the phpize on Ubuntu 20.04 PHP 8.1

I tried following commands but no luck

1. sudo apt-get install php8.0-dev

E: Unable to locate package php8.0-dev

E: Couldn't find any package by glob 'php8.0-dev'

E: Couldn't find any package by regex 'php8.0-dev'

1. sudo apt-get install php-dev

 php-dev : Depends: php7.4-dev but it is not going to be installed

E: Unable to correct problems, you have held broken packages.

1. sudo apt-get install php8.1-dev

E: Couldn't find any package by glob 'php8.1-dev'

E: Couldn't find any package by regex 'php8.1-dev'

My Answer:
It seems like the php8.1-dev package is not available in the default Ubuntu repositories. You may need to add a PPA (Personal Package Archive) that provides the php8.1-dev package.

You can try adding the ondrej/php PPA which provides updated PHP packages for Ubuntu. Here's how you can add the PPA and install the php8.1-dev package:

1. Add the ondrej/php PPA:

sudo add-apt-repository ppa:ondrej/php


2. Update the package list:

sudo apt-get update


3. Install the php8.1-dev package:

sudo apt-get install php8.1-dev


After installing the php8.1-dev package, you should be able to use phpize for compiling PHP extensions.
