Could you please help me to solve this problem.

Please do : $ sudo apt-get update && sudo apt-get install r-base littler

If no luck, new links are required in /etc/apt/sources.list

( Ubuntu 14.10 is not supported any more : End of life.)

→ $ sudo gedit /etc/apt/sources.list

Then replace all text with these 8 new lines :
