我最近安装了 Linaro Ubuntu 12.04 并设置了 cubieboard。
当我尝试运行以下命令时，一切似乎都正常：
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
然后：

sudo: unable to resolve host cubieboard

我之前已将 bfgminer 存储库添加到 /etc/apt/sources.list 文件中：
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
不知道为什么会发生这种情况！等待您的帮助。
答案1
bfgminer 似乎存在一些依赖性问题。要强制安装，请尝试以下操作：
从以下位置下载 bfgminer发射台
打开终端并输入
sudo dpkg --force-all -i bfgminer_3.2.1-0precise1_i386.deb和
sudo apt-get install libjansson4
