How do I get CLI curl to run on debian lenny

Question

I have a machine running debian lenny.
I need to be able to use curl from the command line but it is just not available.
When trying to use it I get:

curl: command not found

What exactly do I need to install to have this command available ?

UPDATE:

I tried to run apt-get install curl and got the following:

xxxxx:~# apt-get install curl

I must be missing something important here...

here is what it says when running apt-get install libcurl3

Solution

You can install it through aptitude:

sudo apt-get install curl

Comments

[el.atomo]

What does it says when running apt-get install libcurl3?

[el.atomo]

It seems to be a problem with your package sources (take a look at your last output: [...] if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming [...]). I would try to update them again (apt-get update) and look for errors. You can also try to generate a new sources.list (debgen.simplylinux.ch) for your distribution, update the sources and install again. Hope it helps.

[epeleg]

I already did an apt-get update - look at the second gray block in the comment. it seems to have some PGP issues near the end, any idea what do those mean ?

[el.atomo]

I guess the PGP warnings are not directly related with your problem. You can read more about it in wiki.debian.org/SecureApt#How_apt_uses_Release.gpg. Could you post your sources.list file?

[epeleg]

added contents of sources.list

[epeleg]

finally. using aptitude install debian-keyring debian-archive-keyring fixed the broken/missing keys I had and now everything works as expected, including curl.
