Unable to install php7.1-bcmath ubuntu 14.04

Question

I have a VPS with ubuntu 14.04, php7.1-fpm installed and running for ages. I am trying to install php7.1-bcmath. it keeps saying

E: Unable to locate package php7.1-bcmath

E: Couldn't find any package by regex 'php7.1-bcmath'

I have already tried adding

add-apt-repository ppa:ondrej/php

and it says:

Press [ENTER] to continue or ctrl-c to cancel adding it gpg: keyring /tmp/tmph26v3afu/secring.gpg' created

gpg: keyring /tmp/tmph26v3afu/pubring.gpg' created

gpg: requesting key E5267A6C from hkp server keyserver.ubuntu.com

gpg:/tmp/tmph26v3afu/trustdb.

gpg: trustdb created

gpg: key E5267A6C:public key "Launchpad PPA for Ondřej Surý" imported gpg: Total number processed: 1

gpg: imported: 1 (RSA: 1) OK

I have also done:

sudo apt-get update

but even after this it says

E: Couldn't find any package by regex 'php7.1-bcmath'

Any help is appericiated.

Answer 1

It seems that the ppa:ondrej/php is no longer supported for trusty(ubuntu 14.04) so i went ahead and ran:

do_release_upgrade()

and i was upgraded to xenial (ubuntu 16.04) Thats the only way i could get a php extension that i did not already have
