Hi Michael, your problem report is a bit difficult to comment upon.
First, this is a debian users mailing list. I think nobody here will feel that they "are" Debian.
Then, you have problems with Sid. Now, Sid is the unstable development version of the distro. On the web page describing the different releases, https://www.debian.org/releases/ the authors stated very clearly that Sid might not work and even mentions disfunctional updates as an example. They also state that users of Sid should subscribe to debian-devel-announce. My conclusion is that problems with Sid should be discussed with the developers community.
And, considering that you tackled a development release, I think it would be useful if you provided details about the problem -- not just the result as in "network doesn't work anymore" but rather some observation of *why* -- which may be software packages that are essential for networking were uninstalled during the upgrade, or provide binaries that do not work. Without such information it will be hard to work on fixes.
Also, you write
There are something over a hundred sites and pages up, that give simple logical instructions about how you install Debian and upgrade to sid. Every one of those pages is currently wrong.
but this is not something the audience of this mailing can take responsibility for.
If you address the right audience with your observations, the problem you found may be fixed. Here, it's unlikely you can get better results than pointers into other directions or just questions of "why Sid?".
Best, Arno
