apache2ctl /etc/apache2/configtest


what should I do? Please help.
Steps I have already taken:
1. Removed all apache2 files multiple times to hard uninstall it and reinstalled it again and again

I don't know why it cannot find /usr/sbin/apache2. That should be installed when you run "sudo apt install apache2". Try removing and reinstalling the apache2 package again, then check to see whether the executable /usr/sbin/apache2 exists.

[wyliecoyoteuk]

try

ls -la /usr/sbin

to see if apache2 is there, and what its permissions are.

in a terminal, issue

apache2ctl -S

and show us the output please.
