Trying to install php with apt-get... Not working

[phpguy]

Hey guys,

I'm running a fresh install of Debian

I'm trying to get php5 via apt-get, but it's not working. Here's what I'm doing

apt-get install php5

Here is the output

E: Couldn't find package php5

Any ideas...?

E: Couldn't find package php5

The package name is not php5 or you do not have a repository in /etc/apt/sources.list that has the PHP package.

The Debian package is called php5.

Which means you either don't have the correct repo in your sources.list or your haven't sync'd with the repos.

First try

apt-get update && apt-get install php5

Failing that post the contents of /etc/apt/sources.list

Thanks guys! When I get to the office, I will post the contents of the sources.list file.

First, I have a few basic questions about this file

1) What IS this file?
2) What does it mean when I don't have the correct repo in this file? I.e. what is a "correct repo?"
3) What does it mean to sync with the repos?

4) What happens when I don't have the repo that has the PHP package, as HROAdmin26 said? Isn't the purpose of apt-get to download and install the package?

Thanks!

Apt isn't some magical application that pulls info about packages out of thin air. Things *change* and are updated - apt has to know where to look to get information about the latest packages, etc.

Google: apt-get sources.list debian

A repository is a collection of software packages. There are official repositories maintained by the developers of a particular distro, and unofficial repositories maintained by members of the community. The official repos should, in theory, maintain higher quality assurance that said software is safe, can meet all it's dependencies, and will work properly with your system. Unofficial repos are generally considered use at your own risk, but there are some well known ones (Debian Multimedia for example) that are generally considered safe.

apt-get has to download the package from some host, be it local on your computer, on a CD, or from the internet. The sources.list file details where to look for packages, again, be it on the internet, locally, or from a CD.

An entry in that file generally looks like

deb http://site.example.com/debian distribution component1 component2 component3

In Debian, you would find something like

deb http://ftp.us.debian.org/debian/ lenny main contrib non-free

So when you use apt, it looks to the above URL, it says you're using the lenny release. (You can also use stable here, of if you're running squeeze, testing.) And it says you have 3 sections enabled, main, contrib, and non-free.

Different software is in different sections, which you can find more about in the link I posted there. But quickly, if a piece of software is in contrib, and you don't have contrib enabled, apt can't find it.

Finally, before apt knows what software is available, it needs to sync with the repository, ie, there's a file in the repository that lists all the available packages and version, which apt scans and stores. When you try to install software with apt, it looks to that info, says, yup, there's a package php5 there, then connects to the repository and attempts to download it.

This can be handy as well for helping to configure your sources.list

What am I doing wrong? I'm reading every tutorial about installing PHP, but nothing is working

Arrrrgghh, I'm driving myself insane. What am I doing wrong? I'm using Debian if that matters.

For what it's worth, here is the result of apt-cache search php- which shows that php5 IS installed.... but it's not recognized at the terminal when i type "php"

The output from the first command shows that php is already installed. PHP is not usually run in a terminal. You create php files, load them to wherever your webserver expects to find web documents and then access the php pages from you web browser. This guide may help.

Hi Daark Child, thanks for the response. I went through the tutorial, however I still get the error bash: php: command not found when I type PHP. Why does it do this, yet show that PHP is installed when I type apt-cache search php5-? Perl works fine on command line, and all the tutorials about installing PHP indicate that typing php -v on command line is the way to verify that it's installed

Also, when I navigate to any PHP/Perl webpage (whether or not the file actually exists in my /var/www/ directory) I get a 403 (Forbidden) error. Again, this error occurs whether or not the php/perl file I am trying to access exists or not. Plain HTML files work fine...

Anyway, I've attached the output for each step in the tutorial you had sent me. Perhaps it might indicate something?
