I need to find out which official Ubuntu versions are recommended for older computers with limited resources. Additionally, I want to know the most effective way to get immediate technical assistance from the Italian Ubuntu community if I encounter an unresolvable problem. Please provide both pieces of information.
Navigate to the 'Derivate' (Derivatives) section of the website, specifically the dedicated page. Identify two official Ubuntu derivatives described as suitable for older or low-resource computers. Navigate to the 'Supporto' (Support) section of the website. Identify the channel recommended for immediate support for 'unresolvable' problems. State the two identified derivatives and the recommended immediate support channel.
Identifies 'Xubuntu' as a suitable derivative for older/low-RAM computers. Identifies 'Lubuntu' as a suitable derivative for older/low-RAM computers. States that 'Chat IRC' is the best tool for immediate support for 'unresolvable' problems. Provides both pieces of information clearly in the final answer.
