Yesterday, I tried to install joomla3.2 package in ubuntu12.04LTS and it successfully installed but the problem I faced is after removing installation files.There showed error as no configuration file.It seems like joomla3.2 removes configuration and database file from package.alternative i tested the joomla2.5   is installed and worked fine.
