Попытка установить расширение phpize на Ubuntu php8.1. ⇐ Php

[Anonymous]

Я пытаюсь установить phpize на Ubuntu 20.04 PHP 8.1
Я пробовал выполнять команды, но безуспешно

• 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'

• 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.

• 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'
