Remove Apache2 From Ubuntu 20.04 Completely

apache2 is a meta-package that just selects other packages. If you installed apache by installing that package, you just need to run this to clean up the automatically selected packages:

#stop the apache2 service

$ sudo systemctl stop apache2

#r emove apache2 packages

$ sudo apt-get purge apache2*

# cleanup

$ sudo apt-get autoremove

# check if the apache has been removed:

#1- following command line should return a blank line

$ which apache2

# If it return a location

apache2: /etc/apache2

# Remove the location

sudo rm -rf /etc/apache2

# 2- following command line should return apache2:

# Failed to start apache2.service: Unit apache2.service not found.

$ sudo systemctl start apache2
