So far, I've been able to use Devuan by creating a local repository with
DebMirror. I don't have internet access at home because I live in the
country I live in, and they don't provide internet access upon request...
things that really happen.

But it turns out that Excalibur doesn't include the binary-all folder in its
access. While Trexie does, it's possible to download Trexis, but not
Excalibur.

http://deb.devuan.org/merged/dists/excalibur/main/binary-all/ -> It doesn't
exist.
http://deb.devuan.org/merged/dists/excalibur/contrib/binary-all/ -> It
doesn't exist.
http://deb.devuan.org/merged/dists/excalibur/non-free/binary-all/ -> It
doesn't exist.

Couldn't these files be included in Excalibur?
It is imperative for me and others who need to create their own repository
using debmirror.
