分享点自己的经验：

sudo apt-get -y build-dep git # 这句有个sgml-data的依赖包装不上，最后手动从官网下载安装的（还有些install和网络代理方面的东西就不提了，没记住）

sudo dpkg-buildpackage -rfakeroot -b # 使用命令sudo update-alternatives --set fakeroot /usr/bin/fakeroot-tcp解决

find $work_path -maxdepth 1 -name "git_.deb" -exec sudo dpkg -i {} ; # 依赖的git-man得先装上，把"git_.deb"换成"git-man_*deb"跑一次解决依赖问题

如果在dpkg-buildpackage -rfakeroot -b编译过程中出现 dpkg-buildpackage: error: failed to sign... 的错误，参考此处 ，修改成 dpkg-buildpackage -uc -us -rfakeroot -b 重新继续编译即可
