I forgot to mention: If you have a separate boot partition, of course
you'd have to mount it into your "$MESSEDUPROOTFS" as well:

$ mount /dev/"$MESSEDUP_BOOT_PARTITION" "$MESSEDUPROOTFS"/boot

Hallo Lars,

you probably know that you also could have booted a live-iso with a
kernel from the same branch and then chroot into your messed up system
to do the downgrades:

$ mount -o bind /dev "$MESSEDUPROOTFS"/dev

$ mount -t proc none  "$MESSEDUPROOTFS"/proc

$ mount -t sysfs none "$MESSEDUPROOTFS"/sys

$ chroot "$MESSEDUPROOTFS"


libre Grüße,

Florian

That happened to me recently and necessitated doing a fresh
installation, since the new packages took out the networking and
bluetooth.  I fortunately have the data and system partitions separated
so that was easy ... and I still had the installation CD's ISO-9660
image still cached locally.

So the situation is not necessarily as rare as one might hope.

Regards,
Lars

I know that, but I was used this is a default in Debian. In Devuan this
is not a default, so I accidently upgraded ALL packages :-(

Thank you! That works great, except downgrading of mysql-server from 5.6
to 5.5 was not possible. Maybe there is something incompatible in
database format.
After downgrade I had to install mysql-server from backports to make it
work again.

Hallo Joachim, 

to avoid accidents like this, I have the following lines in my apt
preferences:


   florian@nulldevice:~$ cat /etc/apt/preferences.d/avoid-otherrepos 
   
   Package: *
   Pin: release a=jessie-backports
   Pin-Priority: 150
   
   Package: *
   Pin: origin "www.deb-multimedia.org"
   Pin-Priority: 75


See apt_preferences(5), section "How APT Interprets Priorities" for
details.


libre Grüße,

Florian

Temporarily bump the priority of stable above 1000, it will downgrade
everything to that release.
