Eu recentemente configurei o cubieboard com o Linaro Ubuntu 12.04 instalado.
Tudo parece estar bem quando tento executar estes comandos:
linaro@cubieboard:~$ sudo add-apt-repository ppa:unit3/bfgminer
sudo: unable to resolve host cubieboard
You are about to add the following PPA to your system:
A CPU+GPU+FPGA miner for bitcoins (and other compatible coins), by Luke Dashjr and others:

OK
Então:
linaro@cubieboard:~$ sudo apt-get update
sudo: unable to resolve host cubieboard

Depois disso, recebo um erro ao tentar instalar o bfgminer:
linaro@cubieboard:~$ sudo apt-get install bfgminer
sudo: unable to resolve host cubieboard
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package bfgminer
Eu adicionei repositórios do bfgminer antes ao arquivo /etc/apt/sources.list:
deb http://ports.ubuntu.com/ubuntu-ports/ quantal main universe
deb-src http://ports.ubuntu.com/ubuntu-ports/ quantal main universe
deb http://ppa.launchpad.net/unit3/bfgminer/ubuntu quantal main
deb-src http://ppa.launchpad.net/unit3/bfgminer/ubuntu quantal main
Não sei porque isso acontece! Esperando por sua ajuda.
Parece haver alguns problemas de dependência com o bfgminer. Para forçar a instalação, tente o seguinte:
Faça o download do bfgminer na barra de lançamento
Abra um terminal e digite sudo dpkg --force-all -i bfgminer_3.2.1-0precise1_i386.deb
e sudo apt-get install libjansson4
