I am trying to install OwnCloud on Ubuntu on AWS EC2. I am following this URL to install: https://download.owncloud.org/download/repositories/stable/owncloud/index.html

My ubuntu version is 18.04. I did first 2 steps (wget and echo) and when I tried to do apt-get update, this is the error I recieve:

    ubuntu@ip-172-xx-xx-254:~$ sudo apt-get update
