Why can't I upgrade php?

manpreet Best Answer 2 years ago

I am running Ubuntu desktop, here's my output from lsb_release -a

No LSB modules are available.
Distributor ID:   Ubuntu
Description:  Ubuntu 16.04.1 LTS
Release:  16.04
Codename: xenial

When I run apt update I get:

All packages are up to date.

Then running php -v

PHP 7.0.8-0ubuntu0.16.04.3 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Xdebug v2.4.0, Copyright (c) 2002-2016, by Derick Rethans
    with Zend OPcache v7.0.8-0ubuntu0.16.04.3, Copyright (c) 1999-2016, by Zend Technologies

However, I have another Ubuntu server running the same lsb_release -a

No LSB modules are available.
Distributor ID:   Ubuntu
Description:  Ubuntu 16.04.1 LTS
Release:  16.04
Codename: xenial

But it has a newer version of PHP installed:

PHP 7.0.13-0ubuntu0.16.04.1 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.13-0ubuntu0.16.04.1, Copyright (c) 1999-2016, by Zend Technologies

I have no PPAs installed on either machine. How can I upgrade my desktop from 7.0.8 to 7.0.13 like what's running on my server?
