Ubuntu 14.10 adalah versi usang dan jika Anda ingin menggunakan, memperbarui & menginstal paket maka Anda perlu mengubah repositori-nya.

Anda dapat melakukan ini dengan cara berikut:

Buka Terminal & jalankan:

sudo gedit /etc/apt/sources.list

Ganti url in.archive.ubuntu.comdan security.ubuntu.comdenganold-releases.ubuntu.com

simpan dan tutup.

Sekarang jalankan sudo apt-get update dan setelah itu instal paket yang ingin Anda instal.
