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:

[email protected]:~$ curl https://install.meteor.com | sh
The program 'curl' is currently not installed.  You can install it by typing:
sudo apt-get install curl
[email protected]:~$ apt-get curl
E: Invalid operation curl
[email protected]:~$ 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:

[email protected]:~$ sudo apt-get install curl

UPDATE 2:

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

UPDATE 3: Did update do sudo apt-get update before i run it.

But this did not help sadly.
