We are using Contabo VPS. It's the cheapest and really awesome. I've built a lot of postal SMTP and Mautic EMS with Contabo. Recently, we are working on the Mailwizz setup. Everything was okay. We install Webmin perfectly. But when we are trying to install Mailwizz with our license, it says cURL is not installed.

I ran these commands:

sudo apt-get update
sudo apt-get install curl
But not working.Can anyone help?
