Upgrading PHP APCu on Ubuntu 14.04 LTS


#1

Ubuntu 14.04 LTS ships with an outdated version of the PHP user cache driver ‘APCu’. OwnCloud, if installed, will complain about this. Here I describe how to upgrade APCu on Ubuntu.

For Ubuntu 16.04 LTS, command to install the PHP 7 developer package is:

$ sudo apt install php-dev

In additions, it is now necessary to add extension=acpu.so to the configuration:

$ sudo vim /etc/php/7.0/apache2/conf.d/20-apcu.ini

I also had to install additional PHP modules:

$ sudo apt install php-zip php-curl

Don’t forget to sudo service apache2 reload afterwards.
