is this what you want?

The command shown above would be used if you want to get the actual source code of the package to examine it or to rebuild the package differently. If you just want a copy of the installable packages, the command would be

apt download name-of-package

You could do this for every installed package to get a full set of .deb packages. dpkg -l will list all installed packages.  Something like this might work for you.

apt download $(dpkg -l | awk '/^ii/ { print $2 }')

The reason you're having trouble finding devuan packages on devuan servers is because most of the packages in devuan get pulled directly from debian and magically merged with the few pure devuan packages to give the impression that we have a repository of 60,000 packages. The software that does the merging is called amprolla. Our own packages are at pkgmaster.devuan.org. Debian's packages are at packages.debian.org.

Another option would be to download the debian dvd set, the devuan server iso and maybe the devuan desktop dvd iso. We don't provide a full dvd set like debian does, so it's possible that some packages might still be missing. But I think most of what you want will be in the debian set. You will have to pull these packages off the media manually to use them or maybe set up a local instance of both debian and devuan repos and amprolla to do the merge and filter out banned packages.

Source code for debian packages can also be found in their git repo, salsa.debian.org
Source code for pure devuan packages can be found at git.devuan.org

apt-cacher might do what you want, too. I don't know much about it.
