apache, mysql and php installation, "package is missing"

[ale13]

Hello,

I am trying to install apache, mysql and php on my ubuntu 14.04 but anytime that I run

#sudo apt-get install apache2, I am havis this issue



Reading package lists... Done

Package apache2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libapache2-mpm-itk

E: Package 'apache2' has no installation candidate



so I try this,

#sudo apt-get install libapache2-mpm-itk

and I get;
