Тамильский How to enable phonetic mode in 14.10?

Эксперт per the earlier findings, I tried with the following commands in терминал mode. But, the Тамил phonetic mode does not get in to the неудар в лунку method of i - i preferences.

sudo apt-get install ibus-m17n

After typing the aforesaid command, the following is the output display.

This may mean that the package is missing, has been obsoleted, or

Help я to enable the Тамил phonetic mode in my system.
