Thanks @jota - that path you specified has a redirection to another folder as per below:
bitnami@ip-172-31-35-155:/opt/bitnami$ ls -la
lrwxrwxrwx 1 root root 15 Aug 13 01:48 joomla -> /bitnami/joomla
I have tried copying to this folder also but when transferring a file I get the following error:
Error: /bitnami/joomla/kickstart.php: open for write: permission denied
Error: File transfer failed
I am able to transfer files to /opt/bitnami/apache/htdocs - and checking /bitnami/joomla/ - both have same permissions:
bitnami@ip-172-31-35-155:/opt/bitnami/apache$ ls -la
drwxrwxr-x 2 bitnami root 4096 Aug 13 03:06 htdocs
bitnami@ip-172-31-35-155:/bitnami$ ls -la
drwxrwxr-x 19 daemon root 4096 Aug 13 01:48 joomla
I need to run -> https://ec2_instance_ip/kickstart.php
Thanks much.
