I'm fresher than the prince to Linux, I've been following the instructions here: (the link tells what I am generally trying to do).

I'm all up and running in VBox, and am at the curl install part, I may have done the curl part a week ago I forget. So I ran this command anyway:

danjah@danjah-VirtualBox:~$ sudo apt-get install curl


[sudo] password for danjah: 
Reading package lists... Done

curl is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.


$ curl | sudo npm_install=rc sh


fetching: {

gzip: stdin: unexpected end of file
/bin/tar: Child returned status 1
/bin/tar: Error is not recoverable: exiting now
It failed

Should I be concerned? How can I test curl? How can I avoid these situations? Perhaps there's a generic way of checking to see if I've already installed packages/etc?

Case specific answers and general advice most appreciated.

cheers, d

I doubt that anything went wrong with your curl install, the fetching: { message comes from the install script curl downloaded for you. In general, if you need to know if a package is installed: dpkg-query -s curl (or whatever package), and look at the line that starts with Status: – taneli Apr 4 '12 at 12:30

What version of Ubuntu are you using? Because 11.10 (and 12.04) have node package manager in the repositories so it can be installed through the software centre or by

sudo apt-get install npm

p.s. If you posted on the forums people would be able to walk you through exactly what you are trying to do.

thanks for the prompt reply - Ubuntu 11.10, yes, and i have npm as I have installed 'connect', 'express' and 'yui3' via npm successfully. I ran the cmd provided anyway, and it has processed and installed npm (again?). No errors, until I try the 'curl | sudo npm_install=rc sh'. You're right I should probably move this to ubuntu forums... I kind of like stackexchange though ;) – danjah Apr 4 '12 at 11:04
