Running gekko on a ubuntu server with apache

[donkykong017]

i tried to set this up on AWS EC2 everything seemed to work but at the last step when i try to set username and PW i get this error:

printf "username:`openssl passwd -apr1`\n" >> /etc/nginx/.htpasswd
Password:
Verifying - Password:
-bash: /etc/nginx/.htpasswd: Permission denied

I tried to google the issue but could not find anything that solved it. tried to set permissions and so on. but cannot seem to write or modify the file.

when i try to start the nginx service i get this error:

service nginx start
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

In the details i see:

systemctl status nginx.service

In the config file the server_names_hash_bucket_size: 64 is set.

can anybody help me set this up. i want to run gekko on AWS EC2 protected from the outside world and accessible from anywhere with basic authentication.
