I upgraded my "testing" system today, and hit a couple of snags
that people might need to know about.

First, I had some references to testing/updates in my
/etc/apt/sources.list; this apparently is now called
testing/security, and apparently it no longer has contrib or
non-free, so I had to change
deb http://security.debian.org/ testing/updates main contrib non-free
to
deb http://security.debian.org/ testing-security main

Second, Debian now requires a confirmation that you understand
that the codename has changed (not a bad idea in itself):

    E: Repository 'http://deb.debian.org/debian testing InRelease' changed its 'Codename' value from 'buster' to 'bullseye'
    N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
    E: The repository 'http://security.debian.org/debian-security testing/updates Release' no longer has a Release file.
    N: Updating from such a repository can't be done securely, and is therefore disabled by default.
    N: See apt-secure(8) manpage for repository creation and user configuration details.
    Aborting on non zero error code: 100!

Turns out if you use "apt update", apt will prompt you and you can
type y. If you're a dinosaur like me and typed "apt-get update", it
simply prints an error message and exits. And although a web search
finds a zillion people who have already hit this, very few of them
actually have the answer, that there's a difference between apt-get
and apt and you have to use the latter.

(Of course I tried the apt-secure(8) manpage first thing; it does
mention that a change in codename now requires confirmation, but
it doesn't say how to do that, or at least I couldn't find it.)
