Upgrade php on Ubuntu 14.04

Wordpress now requires php 5.6 or higher and I just can’t get it to update on my Ubuntu 14.04 droplet, I’ve tried dozens of tutorials but always get a Unable to locate package php5.6 or similar message.

Every tutorial is based around sudo add-apt-repository ppa:ondrej/php but nothing seems to work.

I don’t get any errors when adding the ppa and have also tried LC_ALL=en_US.UTF-8 add-apt-repository ppa:ondrej/php adding the language packs etc, but no joy.

Have used the tutorials here, askUbuntu, Stack and anything else that Google throws up but always get the same Unable to locate message with no progress in resolving that either.

Any help greatly appreciated.

Accepted Answer

I tried with php 7, 7.2 and 7.3 all of which gave me the same Unable to locate package message.

I also tried apt-cache search php and couldn’t see any php7 in there.

I’m pretty lower level with linux so am quite possibly missing something simple.

I’ve looked on Lauchpad and can’t see any reference to Ubuntu 14.04, would this be why it can’t find updates?

php 5.6 is verry old version of php. Wordpress will work with php 7.0 witch is in standard repo , or you can use above mentored repo to download 7.2 repo.
