This question already has an answer here:

I installed a fresh Ubuntu 13.10 on my laptop. Like I usually do, I install the packages I need for Web development, which are nginx, php5-fpm, mysql, php5-mysql, php5-mcrypt and a few others.

After editing some configuration files, this usually works.

But today, since 13.10, an error appears instead of the Web page I expected.

Laravel requires the Mcrypt PHP extension. 

The package php5-mcrypt has been installed and reinstalled.

The command php -m doesn't seem to show mcrypt.

Any idea where the problem could come from? I've done this setup many times and it always worked.

    This is a bug report, ideally, and you should report the bug against php5-mcrypt with ubuntu-bug php5-mcrypt. – Thomas Ward Oct 18 '13 at 1:14
  • @Marc-François there is a typo in your edit to the accepted answer by Tom, instead of mods-avalaible it should be mods-available. – karel Oct 18 '13 at 4:02

I had the same problem after I upgraded to 13.10 this evening. Apparently this is a genuine Ubuntu 13.10 bug: “phpmyadmin do not recognize php5-mcrypt”. The PHP modules got moved from the conf.d directory to the mods-available directory, and the mcrypt module got left behind.

To fix it I put a symlink to the mcrypt.ini file in the PHP config.


If you use Apache (rather than php-fpm):

sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini
sudo service apache2 restart


Or for php-fpm (rather than Apache):

  1. Make symbolic link to ini files in mods-available

    sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/mcrypt.ini
  2. Enable mods

    sudo php5enmod mcrypt
  3. Restart FPM

    sudo service php5-fpm restart

  • Sorry, I do not use Apache. Your other solution for PHP-FPM didn't work. – Marc-François Oct 18 '13 at 1:25

  • Wow... I had been fiddling with laravel for the past 2 days... just wow! Thank you Tom! Love the open source community – Rixhers Ajazi Dec 15 '13 at 2:21
  • This doesn't seem to be required for 14.04 now. Still have to enable it though. – CMCDragonkai Jun 10 '14 at 9:53

Or, use:

sudo apt-get install php5-mcrypt

Im not sure of this will work on standard php installs - I installed php 5.5.7 using the package from:

sudo add-apt-repository ppa:ondrej/php5
sudo apt-get update
