You might want to read this to get an introduction to armel vs armhf.

If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.

Running ARM programs under linux (without starting QEMU VM!)

First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux

If there's no qemu-arm-static in the package list, install qemu-user-static instead

Starting with the situation you have:

cd dpkg-1.18.15
patch -p1 < ../d-m-h-verbose-version-check.patch
will apply the patch. Before building, add a NMU changelog entry (this will avoid having your patched version of dpkg overwritten by apt & co., but will ensure your version is upgraded to the next dpkg release when that's available):

dch -n "Apply d-m-h fix from #844701."
This will rename the current directory (because dpkg is a native package), so you need to change directories again:

cd ../dpkg-1.18.15+nmu1
