How can I enable cURL for an installed Ubuntu LAMP stack?
From Install Curl Extension for PHP in Ubuntu:
sudo apt-get install php5-curlAfter installing libcurl, you should restart the web server with one of the following commands,
sudo /etc/init.d/apache2 restartor
sudo service apache2 restart
You only have to install the php5-curl library. You can do this by running
sudo apt-get install php5-curlClick here for more information.
Try:
sudo apt-get install php-curlIt worked on a fresh Ubuntu 16.04 (Xenial Xerus) LTS, with lamp-server and php7. I tried with php7-curl - it didn't work and also didn't work with php5-curl.
