I run the command `netstat -tulpn | grep 443` (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp6 0 0 :::443 :::* LISTEN - and the command `service apache2 status` ● apache2.service Loaded: not-found (Reason: No such file or directory) Active: inactive (dead) I tried to stop apache2 `systemctl stop apache2` Failed to stop apache2.service: Unit apache2.service not loaded. `systemctl disable apache2` Failed to execute operation: No such file or directory Thank you in advance for your help
