At this point this is as much info as I can get.
Can you help me?
Thanks in advance.
PS: This is after many many manual installation attempts. That always failed when I got to the https configuration and never got it back to work again. BTW loads of assumptions are taken regarding that approach and it's quite a hard learning curve... :frowning:

Since the error said "listen tcp 0.0.0.0:80: listen: address already in use" you should start with looking for the app which uses this address e.g. sudo netstat -peanut|grep ":80"

Here is the result, but I think it's logical...

$ sudo netstat -peanut|grep ":80"
[sudo] password for aabfm:
tcp6 0 0 :::80 :::* LISTEN 0 20943 1531/apache2

Just update the HTTP and HTTPS ports within the .env file to use a different port for owncloud. It’s configurable for exactly cases like that.

This issue isn’t really related to owncloud, you just got already an Apache running on the host that already uses port 80 and possibly 443.
