I have two systems running bookworm, a laptop at 12.13 and a
desktop at 12.11.
I am still able to update the laptop from bookworm repositories but
the desktop refuses, telling me that repositories have changed
"Version" and 'Codename' to various trixie related values.
From this difference in behavior, I speculate that the laptop's
/ets/apt/sources.list uses codenames (for example, "bookworm") to
specify the desired suite in absolute terms whereas the desktop uses
relative terms like "stable".
In other words, (assuming that trixie is stable right now) if you look
in the laptop's sources.list you'll see lines like
deb http://deb.debian.org/debian bookworm main non-free contrib
but in the desktop's you'll see
deb http://deb.debian.org/debian stable main non-free contrib
I would like to stay on bookworm for a while and also to keep the
two systems at the same level.
How would I "fix" this so the desktop will update from bookworm?
Compare the /etc/apt/sources.list on the two devices, and verify that
my guess above is correct.
If so, then the solution is to replace, in the desktop machine's
sources.list, all uncommented instances of "stable" with "bookworm".
If not (that is, if my guess is incorrect) then I don't know what's
going on. And in that case, maybe start by showing us the content of
/etc/apt/sources.list
from the desktop machine.
