I would think that something similar would work for you.

So you could even back up the broken system and still restore the older working version incase you wanted to have the broken one around too. -- hendrik -- To UNSUBSCRIBE, email to debian-amd64-requ...@lists.debian.org with a subject of "unsubscribe".

I do my upgrades using a little script. #!/bin/sh # /root/bin/getafix # Script to save packages to be upgraded in /root/lib/upgrade/$DATE # using dpkg-repack # In case something goes wrong, whilst upgrading, a simple dpkg -i /root/lib/upgrade/$DATE/* # will (hopefully) rebuild a working system. #set -x apt-get update # d-ated dir-ectory DDIR="/root/lib/upgrades/"`date +%Y-%m-%d_%H:%M:%S` echo $DDIR # p-ackages t-o b-e u-pgraded PTBU=`apt-get -s upgrade | grep "The following packages will be upgraded:" --after-context=1 | grep "^ "` echo PTBU="->"$PTBU"<-" if [[ -n $PTBU ]]; then # PTBU non-zero mkdir $DDIR cd $DDIR dpkg-repack $PTBU else echo "No upgrades" fi So if anything goes wrong i only have to cd /root/lib/upgrades/`date +%Y-%m-%d_%H:%M:%S` and dpkg -i * When dist-upgrading this will probably produce tons of packages in /root/lib/upgrades/ Another way would be to simply copy the partitions involved (with dd) make the upgrade and write them back i anything goes wrong.

is there a way to revert to a previous, known working set of debian packages?
I'm comfortable using Debian/Unstable. I accept that things can go wrong, and I'm willing to file bugreports. However, I do wonder if there is any way to make snapshot of the current versions of all packages, then update, and then, if necessary, revert back to the previous snapshot. I seem to have upgraded to a non-working X last evening, where xserver-xorg-core depends on something that isn't release yet. I don't mind doing without X for a few days, but I did wonder if there is an easier way to say 'just get back to this known-working list of packages', instead of trying to install the correct versions manually, which gets rather tiresome when there's a lot of packages. The internet revealed 'apt-clone', which comes close, but seems to work only with ZFS and more like a general rollback tool, than just packages. How do other users do this?
