Ubuntu 12.04.5 is installing Apache 2.4 not 2.2

Question

I have a VPS running Ubuntu 12.04.5, lsb_release -a output:

No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 12.04.5 LTS Release: 12.04 Codename: precise 

However, running

sudo apt-get install apache2 

Installs apache 2.4, not apache 2.2 as I expected. The output of "apache2 -v" is:

Server version: Apache/2.4.12 (Ubuntu) Server built: Feb 4 2015 14:21:10 

The contents of my /etc/apt/sources.list is:

deb http://archive.ubuntu.com/ubuntu precise main restricted universe deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe deb http://security.ubuntu.com/ubuntu precise-security main restricted universe multiverse deb http://archive.canonical.com/ubuntu precise partner 

As I understand, isn't Ubuntu 12.04 meant to use Apache 2.2? How can I get the server to install the correct version of Apache?

I had to remove http:// from the sources.list quote as I don't have enough reputation to post the links, but the http is there in the actual file.

Answer 1

The solution was to check in /etc/apt/sources.list.d as suggested by Michael Hampton. I had some extra sources in there.

Answer 2

First check what are the packages available,

apt-cache showpkg <pachagename> 

The above command will display list of available versions for this package. Check if your version is available post that you can specify version for installation.

apt-get install <packagename>=<complete version name> 

Example:

apt-cache showpkg apache2 apt-get install apache2=2.2.14-5ubuntu8.7
