IN this post I am going to show you how to install CURL on the Ubuntu Linux server. It is fast and easy and not as hard as you think.

Log Into Your Server

SSH into your server. If you are not familiar with logging in via SSH please see SSH Tutorial here. After you are logged into your server you will want to follow the steps below.

Download CURL to Ubuntu Linux Server

Enter the follow command line to make sure that you are in the uppermost directory. It may not matter but as a precaution I recommend it. :-) Notice there is a space between the "cd" and the "/" forward slash.

cd /

Next enter this command. It will download and install CURL into your Linux system.

sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

Your screen will look something like this. Next you want to restart your Apache server with the following command line.

sudo service apache2 restart

  Congratulations you just installed CURL onto your Ubuntu Linux server! :-) If you have any problems you can try the following command lines. This is for the Linux servers that are giving the error that CURL has already been downloaded.

sudo add-apt-repository ppa:costamagnagianfranco/ettercap-stable-backports

Then

sudo apt-get update

Then

sudo apt-get install curl

For PHP7 Just use This

sudo apt-get install curl

Have a nice day! :-)
