So, you're running PHP7.2 but can't install php7.2-mcrypt like you used to?
# install dependencies
sudo apt-get -y install gcc make autoconf libc-dev pkg-config
sudo apt-get -y install php7.2-dev
sudo apt-get -y install libmcrypt-dev
# use PECL to install mcrypt
sudo pecl install mcrypt-1.0.1
Since PECL is ancient now, it doesn't actually enable the extension once it's built (unless you have PECL configured so that it knows where your php.ini file is). You'll know that you need to do more if PECL tells you:
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini
Or, simply ask php:
php -m
If there is no 'mcrypt' in the output, PHP doesn't know that it's installed.
Although you can add the required line into php.ini; on Ubuntu/Debian you will find module-specific *.ini files in /etc/php/7.2/mods-available/ Just copy one to 'mcrypt.ini', and change the contents so that it contains
extension=mcrypt.so
Once that's done, tell PHP about it:
sudo phpenmod mcrypt
# confirm with
php -m | grep mcrypt
Now, tell Apache to use your new PHP module:
sudo systemctl reload apache2
# confirm with
php -i | grep mcrypt
