Hi, I'm trying to install Apache on Xubuntu 8.10, and I get this:

Code:

aaron@aaron-laptop:~$ sudo apt-get install apache2
Reading package lists... Done
Building dependency tree       
Reading state information... Done
apache2 is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  apache2-mpm-worker: Depends: apache2.2-common (= 2.2.9-7ubuntu3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Does anyone know how to fix this?
Thanks in advance.

It told you it needed apache2-mpm-worker as a dependency to apache2. the first thing you should have tried is

sudo apt-get install apache2 apache2-mpm-worker

The only guess I have as to why it didn't do that automatically, is because there are several options for the Multi-Processing Module (MPM) package.

Code:

p   apache2-mpm-event                                      - Apache HTTP Server - event driven model                         
p   apache2-mpm-itk                                        - multiuser MPM for Apache 2.2                                    
i A apache2-mpm-prefork                                    - Apache HTTP Server - traditional non-threaded model             
p   apache2-mpm-worker                                     - Apache HTTP Server - high speed threaded model

Here are all the packages installed for my apache2 server, as an example..

Code:

it-etch:/$ aptitude search  ~i | grep apache2
i   apache2                         - Apache HTTP Server metapackage            
i A apache2-mpm-prefork             - Apache HTTP Server - traditional non-threaded
i A apache2-utils                   - utility programs for webservers           
i   apache2.2-common                - Apache HTTP Server common files           
i A libapache2-mod-php5             - server-side, HTML-embedded scripting language

Hope that helps.

When I did sudo apt-get install apache2 apache2-mpm-worker, it gave me the same error.
