Removing and reinstalling apache2 returns in error

I fully removed apache2 installation from my Raspbian installation:

sudo apt-get remove apache2 sudo rm -rf /etc/apache2/

When i want to reinstall it again:

sudo apt-get install apache2

I get the following error message:

Why does the apt-get installation not include the conf file? What can I do now, now that i've fully deleted the apache2 folder?
