I'd like to try PHP7.0 on Debian Jessie and am trying to install it from sid. However, php7.0 depends on php7.0-common which depends on php-common > 18 while php-common in sid is at 17. Does this mean it's simply impossible to install php7.0 from this distribution at the moment? Why is that?

I know that it is possible to install from source as explained e.g. here, I'm just asking about the official packages.

Note: the packages in sid have been fixed and it is now (Jan 6, 2016) possible to install from there.

You have unofficial repos with new versions. Using Debian one of the best well-known repository for most up-to-date software for web servers for i386 and amd64 packages is dotdeb.

"Dotdeb is an extra repository providing up-to-date packages for your Debian servers"

They have PHP 7 since the 3rd of December (of 2015), and have had a pre-packaged beta since November.

To add the dotdeb repository, from here.

Edit /etc/apt/sources.list and add

deb http://packages.dotdeb.org jessie all

Fetch the repository key and install it.

wget https://www.dotdeb.org/dotdeb.gpg
sudo apt-key add dotdeb.gpg

Do then

sudo apt-get update

And lastly:

sudo apt-get install php7.0

To search for php 7 related packages:

apt-cache search php | grep ^php7

In Ubuntu you also already have PPAs for it too.

It seems Debian backports do not have yet PHP 7.0. Search here in a near future.

  • The debian 7 packages are not always installing properly. I am running cloud services and installed the debian package for php extensions thousands of times automated. There is a chance of like 1:50 that the package is partially failing on install and needs a second "dpkg -i". I could not find the reason so far, I solved it through a loop which installs each extension until it is working.

  • Interesting. I had a similar problem with random stalls/hangups in automated installs and had to introduce timeout parameters. They were not limited to a particular repo. Oct 24, 2016 at 6:49

    Yea, I am using a loop in a bash script which tests with "php -r" if the function works and repeats the dpkg install process until it does work. It happens randomly and on the same linux image, so exactly the same start conditions.

Add the main repository to your sources.list : Depending on your distribution (Jessie, Wheezy or Squeeze), add these two lines to your /etc/apt/sources.list file.

deb http://packages.dotdeb.org jessie all
deb-src http://packages.dotdeb.org jessie all

For PHP 7.0 on Debian 8 “Jessie” (rc3), add these two lines too :

deb http://packages.dotdeb.org jessie-php7.0 all
deb-src http://packages.dotdeb.org jessie-php7.0 all

Fetch and install the GnuPG key :

wget https://www.dotdeb.org/dotdeb.gpg
sudo apt-key add dotdeb.gpg

Run apt-get update && apt-get install php7-*
