php7.1-imap module won't install on ubuntu 16.04?

Question

PHP

Hi friends.

I can’t install php7.1-imap from the repo, it says that there is no such package.

apt install php7.1-imap

I also connected ppa ondrej, and update upgrade and everything is as usual. But he writes that there is no such thing.

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update

What to do in this case? do not offer a new serv and php version above, this is production.

I needed php 7.2 for this version, I found a working ppa. I can throw off

UPD
repo from which I have 7.1

sudo add-apt-repository 'deb de.archive.ubuntu.com/ubuntu xenial main universe'
