执行apt-get install xxxx时，报以下错误

E: There are problems and -y was used without --force-yes

解决方案：

vim /etc/apt/sources.list 

删除原有，添加如下：

deb http://old-releases.ubuntu.com/ubuntu/ natty main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ natty-security main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ natty-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ natty-proposed main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ natty-backports main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ natty main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ natty-security main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ natty-updates main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ natty-proposed main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ natty-backports main restricted universe multiverse  

注意：这里使用的是ubuntu的源，也可以网上找源去，不过bt系列的源已经停止更新了，部分软件已经找不到了

kali可以添加以下源：

deb http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib
deb-src http://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib

替换源

apt-get update

如果把源改了以后，在bt5上执行apt-get install xxx时报以下错误

E: Sub-process /usr/bin/dpkg returned an error code (1)

处理方法：来源（http://yanue.net/post-123.html）

mv /var/lib/dpkg/info /var/lib/dpkg/info.bak //现将info文件夹更名

mkdir /var/lib/dpkg/info //再新建一个新的info文件夹

apt-get update

apt-get -f install

mv /var/lib/dpkg/info/* /var/lib/dpkg/info.bak

rm -rf /var/lib/dpkg/info //把自己新建的info文件夹删掉

mv /var/lib/dpkg/info.bak /var/lib/dpkg/info //把以前的info文件夹重新改回名字

apt-get update

最后：bt系列的源不再更新了，上述方法可能不能够完全解决你的问题，建议用kali去做任务
