Hello! I’m trying to install WHMCS on Ubuntu 20.04 (LTS) x64 running Webmin, it seems a CURL with SSL Support is required according to the installer. I have tried many solutions online but non worked for me. Please have anyone encountered such problem? Or any solution? Thanks!

Hi there,

Installing php-curl resolved the issue for me.

sudo apt-get install -y php-curl

Hi Alex! Thanks for all your support. I ran from steps VI and VII, same thing! I think where the whole problem lies is in step V, that line is where the whole configuration lies. It means if I can’t configure it with an SSL support, the whole thing is invalid. If I can get another process of running that command, I think the problems would better be solved. Checking the cURL version with curl --version or $ curl -V still shows no https support.

Hello there, @Chijioke

You can try running the commands from steps VI and VII and let me know how it goes!

Hello @Chijioke

Are you trying to install WHMCS manually or via Webmin as an additional addon for the control panel? I will also recommend installing OpenSSL as per Bobby’s reply.

You can check the full recommended requirements:

Also, check the requirements on the WHMCS site here:

PHP Version: Latest 7.3 or 7.4 Release PHP Memory Limit: 128MB PHP Database Extension: PDO PHP Extensions:

  • Curl with SSL
  • GD2 Image Library
  • JSON Support
  • XML
  • Iconv
  • MBString
  • GMP
  • OpenSSL
  • BC Math
  • Intl

MySQL Version: Latest 5.7 Ioncube Loaders: The latest 10.x Ioncube for your PHP version

As part of PCI compliance, an SSL library capable of TLS 1.2 may be required. If using OpenSSL, version 1.0.1c or newer is recommended.

If you’re installing it manually follow the steps listed on this site here:

Hope that this helps! Regards, Alex

Hi there,

I believe that you need to install OpenSSL in order to get that working.

If you are on an Ubuntu server, you could do that with the following command:

sudo apt install openssl

Let me know how it goes! Regards, Bobby
