I am trying out Meteor http://meteor.com/examples/leaderboard

I have to use CURL, which I am familiar with on Windows.

Now I try to install it on Ubuntu 12.04.

But i get these errors:

kevin@ubuntu:~$ curl https://install.meteor.com | sh

The program 'curl' is currently not installed.  You can install it by typing:

sudo apt-get install curl

kevin@ubuntu:~$ apt-get curl

E: Invalid operation curl

kevin@ubuntu:~$ sudo apt-get curl

[sudo] password for kevin: 

E: Invalid operation curl

How do i install CURL?

SOLVED IT:

I did this command

sudo sed -i -e 's/us.archive.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list

and then I could do sudo apt-get update and then sudo apt-get install curl

which successfully installed curl.

UPDATE:

Sorry for the obvious mistake. I tried yesterday also, and there I did type the right command which, gave me this error message:

kevin@ubuntu:~$ sudo apt-get install curl

UPDATE 2:

Tried the apt-cache search curl | grep -i curl command

kevin@ubuntu:~$ apt-cache search curl | grep -i curl
