2.) Changing ports In order to get the port 80 and 443 free for Nginx later, we need to change the port of the Nextcloud apache server. - open an ssh terminal of your joice (like putty for Windows) and connect to the pi via ssh - type in: sudo nano /etc/apache2/ports.conf     - look for port 80 ; change it to 8080 - look for port 443 ; change it to 4430 - save with STRG+O and exit out with STRG+X - type in : sudo nano /etc/apache2/sites-available/000-default.conf     - search for virtualhost ; change ist to 8080   - type in : sudo nano /etc/apache2/sites-available/nextcloud.conf     - search for virtualhost ; change it to 4430 - save with STRG+O and exit out with STRG+X   - now your Nextloud web page will be accessable under port 8080 and 4430 for ssl
