我提出了一个错误报告并被要求应用补丁其中看看它是否有效。我试图找到有关如何进行此操作的文档，但尚不清楚。
我能弄清楚的最接近的是http://www.thegeekstuff.com/2014/12/patch-command-examples/。
我通过 apt-get 下载了最新的源代码，位于名为 dpkg 的目录下 -
$ sudo apt-get source dpkg
看起来是这样的——
[shirish@debian] - [~/games/dpkg] - [5692]
└─[$] pwd
/home/shirish/games/dpkg
这就是路径，就在这里 -
┌─[shirish@debian] - [~/games/dpkg] - [5691]
└─[$] ls
d-m-h-verbose-version-check.patch dpkg-1.18.15 dpkg_1.18.15.dsc dpkg_1.18.15.tar.xz
我想在应用补丁之前进行备份并进行试运行，但需要知道我应该期望哪些命令和输出。另外，我通常使用 -
$ fakeroot debian/rules build
$ fakeroot debian/rules binary
构建本地 deb 包。这够好吗？
更新1- 那没用-
┌─[shirish@debian] - [~/games/dpkg] - [5710]
└─[$] cd dpkg-1.18.15
┌─[shirish@debian] - [~/games/dpkg/dpkg-1.18.15] - [5711]
└─[$] dch -n "Apply d-m-h fix from #844701."
dch: fatal error at line 569:
debian/changelog is not writable!
那么我是否需要使用 sudo 来具有写访问权限或使用 chmod 来更改权限/权限。我想以正确的方式去做。
更新2- 重做了整个事情，这次以正确的方式，卡在修补阶段 -

答案1
从你现在的情况开始：
cd dpkg-1.18.15
patch -p1 < ../d-m-h-verbose-version-check.patch
将应用补丁。在构建之前，添加 NMU 更改日志条目（这将避免您的修补版本dpkg被 & co. 覆盖，但将确保您的版本在可用时apt升级到下一个版本）：dpkg
dch -n "Apply d-m-h fix from #844701."
这将重命名当前目录（因为dpkg是本机包），因此您需要再次更改目录：
cd ../dpkg-1.18.15+nmu1
为了构建，我倾向于使用
dpkg-buildpackage -us -uc
.deb这将在父目录中生成各种文件；您可以dpkg像平常一样安装它们。
（debian/rules显式调用目标也可以；但是您不应该使用fakerootfor debian/rules build，而只能使用 fordebian/rules clean和debian/rules binary。）
添加 NMU 更改日志条目还可以确保您下载的源代码保持不变，从而解决您的备份问题。这也意味着重新安装 1.18.15 版本将恢复 Debian 版本，无需您的补丁。
