Я испытываю Метеор http://meteor.com/examples/leaderboard

Я должен использовать ЗАВИХРЕНИЕ, с которым я знаком в Windows.

Теперь я пытаюсь установить его на Ubuntu 12.04.

Но я получаю эти ошибки:

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

Как я устанавливаю ЗАВИХРЕНИЕ?

РЕШЕННЫЙ ЭТО:

Я сделал эту команду

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

и затем я мог сделать sudo apt-get update и затем sudo apt-get install curl

какое успешно установленное завихрение.

ОБНОВЛЕНИЕ:

Извините за очевидную ошибку. Я попробовал вчера также, и там я действительно вводил правильную команду, которая, дал мне это сообщение об ошибке:

kevin@ubuntu:~$ sudo apt-get install curl
[sudo] password for kevin:

ОБНОВЛЕНИЕ 2:

Но это не помогло печально.
