Your issue is due to insufficient directory permissions. To resolve this, change the owner of the directory accordingly:

First, you will directory user ownership to a specific non-root user using this command:

$ chown -R {user_name}:{user_group} {target_directory}

Ex: $ chown -R uvdesk:uvdesk community-skeleton

Second, add this user to the www-data apache user group using the following command:

Add user to www-data group:

$ usermod -aG {user} www-data;

Ex: $ usermod -aG uvdesk www-data;

Verify that the user has been added to the www-data group:

$ groups <your-user-name>;

Ex: $ groups uvdesk;
