Ubuntu 16.04 - PHP 7.1.11 to 7.1.3

Question

How can I upgrade my PHP version from PHP 7.1.11 to 7.1.3 on my Ubuntu 16.04 server? I've tried the following:

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install php7.1

But them I'm getting the following response:

php7.1 is already the newest version (7.1.16-1+ubuntu16.04.1+deb.sury.org+1).

Also tried to do the following:

sudo apt-get install php7.1.3

But then I am getting this error:

E: Unable to locate package php7.1.3
E: Couldn't find any package by glob 'php7.1.3'
E: Couldn't find any package by regex 'php7.1.3'

How can I upgrade minor version?

Solution

Since official repo comes with 7.0 version, repo from ondrej/php has 7.1

Add the repository :

sudo add-apt-repository ppa:ondrej/php

Update :

sudo apt-get update

Install 7.1:

sudo apt-get install php7.1 php7.1-common

if needed you can remove old packages:

sudo apt-get purge php7.0 php7.0-common

You are not upgrading, in fact, you are degrading your php version.

This only installed 7.1.25 for me
