Where did php7.1-xml go?

Question

PHP

We roll out the project on the chest into production, bring the environment into line.
Composer update, yeah, missing php-xml. And then the mysticism begins:

How to overcome the absence of php-xml / php7.0-xml / php7.1-xml ? PPA was added, it's still not there and that's it. What is it like???
PS The axle is old, 12.04

Answer 1

there, in fact, there are no such rotten versions of ubunta with php xml)))
Apparently, no one needs to support the three-year version.
