Package 'php5' has no installation candidate 에러 해결방법

Package 'php5' has no installation candidate

Ubuntu 16.04 에서 php5를 설치하려고 하면 위와 같은 에러가 발생한다.

이는 php7이 default 이기 때문인데 다음과 같은 방법으로 해결할 수 있다.

Ubuntu 16.04 comes with PHP7 as the standard, so there are no PHP5 packages

However if you like you can add a PPA to get those packages anyways:

Remove all the stock php packages

List installed php packages with dpkg -l | grep php| awk '{print $2}' |tr "\n" " " then remove unneeded packages with sudo aptitude purge your_packages_here or if you want to directly remove them all use :

sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`

Add the PPA

sudo add-apt-repository ppa:ondrej/php

Install your PHP Version

sudo apt-get update
sudo apt-get install php5.6

You can install php5.6 modules too ..

Verify your version

sudo php -v
