I have installed php and apache2 server before but I'm getting bogged down with errors.

The process so far is as follows:

sudo apt-get install tasknet

sudo apt-get install lamp-server

During the installation, tasksel stops with

tasksel: aptitude failed (100)

I tried:

sudo tasksel remove lamp-server

sudo apt-get install lamp-server

With the same error

Next I tried

sudo apt-get update && sudo apt-get upgrade

with the following result:

So I tried:

Errors were encountered while processing:

 mysql-server-5.5

 php5-cli

 libapache2-mod-php5

 mysql-server

 php5-mysql

After looking through these errors, I tried installing mySQL server again manually with

sudo apt-get install mysql-server-5.5

but got the same errors as I recieved in the last set of errors.

I ran

 sudo tasksel --test

with the following result:

debconf-apt-progress -- apt-get -q -y install lamp-server^

so I ran this command with sudo and at 15% it said installing mysql-server then on to mysql-com at 18% where it stopped.

Ran through a few of the commands I had already tried with the same results.

The Question.

Please can you advise what I should do next?

UPDATE

I entered sudo apt-get update && sudo apt-get upgrade and after downloading and checking the packages the following report was given:

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

6 not fully installed or removed.

After this operation, 0 B of additional disk space will be used.
