At once I faced an issue, while created a new account through WHM it was creating frontpage extensions and the image folder under public_html directory by default. Due to which I was not able to install joomla getting the error as :

The installation can not be completed:
- You chose to install in the main directory of the domain temp.****.com, but there are conflicting filenames, therefore we can not proceed. Following filenames already exist in the main directory of the domain temp.****.com (path="/home/****/public_html/temp/").You must manually remove these files before proceeding with auto-installation:
images

Solution : I checked my hosting packages and they were having frontpage extensions installed so I have edited the packages and the issue resolved.
