Duplicator Permissions Fail on Google Cloud Bitnami Stack

Hi guys,

I am familiar with setting up LAMP stacks and the like, however i have chosen to focus mainly on building my client websites rather than server administration and the like.

I intend to eventually move all of my client websites into a single wordpress multisite however for the purposes of testing i have installed only a single instance of WordPress using the Bitnami stack (launched/installed from within my google cloud console directly not from bitnami website)

I have installed the duplicator plugin however i note that the following issue arises…

Permissions Fail
Required Paths
-Fail [/opt/bitnami/apps/wordpress/htdocs/]
-Fail [/opt/bitnami/apps/wordpress/htdocs/wp-snapshots]
-Fail [/opt/bitnami/apps/wordpress/htdocs/wp-snapshots/tmp]

Permissions can be difficult to resolve on some systems. If the
plugin can not read the above paths here are a few things to try. 1) Set
the above paths to have permissions of 755 for directories and 644 for
files. You can temporarily try 777 however, be sure you don’t leave them
this way. 2) Check the owner/group settings for both files and
directories. The PHP script owner and the process owner are different.
The script owner owns the PHP script but the process owner is the user
the script is running as, thus determining its capabilities/privileges
in the file system. For more details contact your host or server
administrator or visit the ‘Help’ menu under Duplicator for additional
online resources.
