I *can* in fact already do that, as dpkg is already packaged and inside Arch Linux's repositories [1]. The reason I'm wanting to do it manually is that I'm appearing to get quite a bit of a speed gain from doing so. On relatively tiny packages, it doesn't make much of a difference, but as I'm creating more bulky-sized packages, the difference is appearing to make more and more of a difference. It doesn't appear to be some kind of placebo effect either - running 'time dpkg -b package/' has always shown to be churning out a package slower than 'time /script.sh', where 'script.sh' would contain, again, the commands found in my project [2]. Lastly, to wrap it all up then: This isn't a problem with the available tools on any given distro, but rather a problem with speed that I'm wishing to solve (likewise by creating the package manually, but alas the size issue with APT is still cropping up).

Maybe as dpkg does a bit more than just tar and stuff while building
packages, but no, this message is due to a bug of sorts in apt:
https://salsa.debian.org/apt-team/apt/-/merge_requests/177
The changes are already merged to main and should be in experimental,
which was also the only release pocket effected in Debian (well,
technically the misconception as such is a few years old, but the
code equally hiding and bringing it to light is not).
Not sure about the state in Ubuntu, but I guess its only their
development release und only until the next sync/upload.
You can btw use -o Acquire::AllowUnsizedPackages=1 to disable this check.
Or, simply don't try to reinstall packages for (probably) no reason…

The question is: why are you attempting to create the .deb yourself,
instead of using Debian tooling. Can't you simply build dpkg under Arch
and try to use it directly?

Issue with installing manually created Debian archive with APT
I'm working on a project that [1] that aims to bring the PKGBUILD format used
on Arch Linux to Debian. That's besides the point though, and it's mainly just
to help showcase what I'm doing brought me to my current issue.
Anyway, part of the process that my program previously used is running 'dpkg
-b' to build a directory layout into a .deb package. This always seemed to take
forever though, and I've since gone with just creating the .deb package
manually [2] with tar and ar.
When I try installing the packages my program builds (with 'apt install
./debname.deb'), it works fine. But if I then try to reinstall the package
(with 'apt reinstall ./debname.deb'), this error keeps popping up for some
reason (the variables surrounded by '{}' represent values in a control file):
Repository is broken: {Package}:{Architecture} (= {Version}) has no Size
information
Is there anything I'm doing wrong when creating the .deb package (mainly
concerned with link 2 where the actual package creation takes place)? I've
tried looking at 'dpkg-deb/build.c' in dpkg's source code [3] to see what dpkg
might be doing when building packages, but nothing I tried got me to any
solution.
