Ubuntu Xenial will not ship
php5 at all.
The only way to get continued
php5 access is to use a PPA, specifically Ondřej Surý’s PPA for co-installable php5 and php7.0. However, this is not supported by the Ubuntu Server Team or the Ubuntu Security Team, and you accept the risks therein of using PPAs for getting
The packages are *not* named
php5 but are instead named
So, to add
php5.6-fpm to Xenial, you would do something like this to add the PPA, update, and then also install
php5.6-fpm and dependencies:
sudo apt-get install python-software-properties sudo LC_ALL=en_US.UTF-8 add-apt-repository ppa:ondrej/php sudo apt-get update sudo apt-get install php5.6-fpm
(Note that I have not tested this; this is, however, supposedly usable based on user experience data gathered on Ask Ubuntu by myself.)
This should be a similar process for any of the other
php5.6 packages you would need. However, you do NOT need to re-add the PPA if it’s already on your system.
