From: Liviu Andronic on 20 Apr 2010 15:00 Dear all What files contain the information on the current ("now") apt tree? I would like to perform backups of these files so that I could restore the tree if some package upgrade messed up my Debian testing.

Restoring those files would not actually cause a downgrade to occur. They would just cause the state of the package manager to not accurately reflect the state of the system. -- Unless I'm misunderstanding what you mean by "apt tree". If you need an old package, snapshot.debian.org should have it. You can then you pinning to avoid upgrading it -- either to a specific version or at all. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss(a)iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/

I would like the package manager to switch back to the previous state. Then, I would open aptitude and it will automatically propose the necessary downgrades (I think). Thus I could quickly and painlessly restore the system (in case it was broken by the upgrade) and then hunt down the offending package when time permits. What would be the concerned files? > -- Unless I'm misunderstanding what you mean by "apt > tree". > > If you need an old package, snapshot.debian.org should have it.  You can then > you pinning to avoid upgrading it -- either to a specific version or at all. > Looks interesting, I'll look into that.

If you are asking what I think you are asking, as in which files would you need to restore your system in the event that you lose your apt and dpkg databases, then I do the following: /var/backups /var/cache/apt (less /var/cache/apt/archives) /var/lib/apt /var/lib/dpkg This will give you enough that apt-get update, etc works. Now the rules have probably changed if you use aptitude as I believe it creates/uses a different database.
