安装libssl-dev报错：

The following packages have unmet dependencies:

  libssl-dev: Depends: libssl0.9.8 (= 0.9.8k-7ubuntu8.6) but 0.9.8k-7ubuntu8.8 is to be installed

E: Broken packages

有人在backtrack-linux.org论坛上给出解决方案：

Add the following to /etc/apt/sources.list :

    deb  lucid-security main

然后apt-get update后重新安装后成功！
