Apt is NOT built for downgrading.
Agree.
Ah I see, I did not realise that's what you meant by downgrading it,
thanks.
The thread is becoming excessively long. Have you posted output of "apt
policy" to figure out what is your current configuration? You must have
either additional config or pinning besides sources list for testing.
Out of curiosity I have tried to install sendmail and openssh-server
from testing. I removed testing from sources list, dropped the following
file
/etc/apt/preferences.d/80-downgrade.pref
Package: *
Pin: release n=bookworm
Pin-Priority: 1001
and after
apt upgrade
only a couple of packages from testing survived:
libdb5.3t64/now 5.3.28+dfsg2-7 amd64 [installed,local]
libssl3t64/now 3.2.1-3 amd64 [installed,local]
I have no idea if all sendmail state and spool files have compatible
format. So arbitrary failures may be expected.
Before downgrade it was:
