我之前使用的是 ubuntu 10.04，我尝试安装bitcoind。失败了，我升级到了 ubuntu 12.04。当我运行时bitcoind它仍然不起作用：
$ bitcoind
************************
EXCEPTION: 11DbException
Db::open: Invalid argument
bitcoin in AppInit()
terminate called after throwing an instance of 'DbException'
what(): Db::open: Invalid argument
Aborted (core dumped)
再次尝试安装也不起作用：
$ sudo apt-get install bitcoind

我该如何开始bitcoind工作？如果需要的话我不介意卸载并重新安装...
