Install PHP 7 on a fresh Ubuntu VPS: [Fix] Unable to locate package PHP

Updated on September 1, 2017

Recently one of my client provided a fresh VPS and asked me to install PHP 7, Apache and MySQL. While installing PHP, I encountered the below error:

root@webimage:~# apt-get install php
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package php

Solution: By default PHP5.5 is only available for Ubuntu Trusty in the standard Ubuntu repositories. So, you can install PHP 5.5 version as shown below:

#apt-get install php5

Unable to locate package PHP

How to Install PHP 7?

If you want to install PHP 7 and the same is not available in standard Ubuntu Trusty repository. Then you need to add the corresponding repository which includes PHP 5.6 and above versions.

Add the below repositories in your ubuntu:

root@webimage:~# add-apt-repository ppa:ondrej/php
 Co-installable PHP versions: PHP 5.6, PHP 7.0, PHP 7.1 and most requested extensions are included.
 PLEASE DON'T USE PHP 5.4 OR PHP 5.5. The PHP 5.5 and later are no longer supported with security updates, therefore they are not included in this repository.
 You can get more information about the packages at
 BUGS&FEATURES: This PPA now has a issue tracker:

You need to update the repository

As stated earlier, you can install PHP versions of 5.6, 7.0 and 7.1 as below:

For installing PHP 5.6

#apt-get install php5.6

For installing PHP 7.0

# apt-get install php7.0

For installing PHP 7.1
