无法在Raspbian上安装php 7.2

Question

I cannot install php 7.2 on Raspbian. I used the last Raspbian (Release date : 2017-11-29) with a Debian Stretch 9.1 : https://www.raspberrypi.org/downloads/raspbian/

I followed the instructions from https://www.colinodell.com/blog/2016-12/installing-php-7-1 :

apt-get install apt-transport-https lsb-release ca-certificates
wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
echo "deb https://packages.sury.org/php/ $(lsb_release -sc) main" > /etc/apt/sources.list.d/php.list
apt-get update

But when I try

apt-get install -y php7.2

A get the below errors :

root@raspberrypi:/home/pi# apt-get install -y php7.2
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 php7.2 : Depends: libapache2-mod-php7.2 but it is not installable or
               php7.2-fpm but it is not installable or
               php7.2-cgi but it is not installable
      Depends: php7.2-common but it is not installable

Someone can help me ? Thanks a lot

Answer 1

I found the reason, the package php7.1 and php7.2 isn't in the stretch repo :(.

Have to wait an update ...

Please check this GitHub issue: https://github.com/oerdnj/deb.sury.org/issues/579

It seems that Debian packages for newer PHP versions are not yet released for the ARM architecture. I would like to contribute for building such packages, but there is no activity on the issue after my last post.

An option to install PHP7.1 or newer would be to compile and install it yourself. For some examples, you may want to check http://yoestuve.es/blog/compile-php-7-for-raspberry-pi-with-memcached/ . I would also suggest to use checkinstall instead of make install in order to facilitate easier uninstallation later.

Unfortunately it does not look like there will be a higher version than PHP 7.0 for raspberrys with stretch. Here you can see the PHP versions for current and future raspbian releases: https://packages.debian.org/search?arch=armhf&searchon=names&keywords=php

You will have to upgrade to buster, then you will get PHP 7.3. Here is how: https://www.raspberrypi.org/blog/buster-the-new-version-of-raspbian/
