Panic! How to downgrade an update that you don't know?

English Install/Boot/Login

Hi all,
this is the first time I write!
I am on OpenSuSE 11.3.

My problem:
I am using a very bugged code written by some scientists and I need it working, otherwise someone will kill me soon :slight_smile:
It was working few days ago and now it doesn’t. I guess this is due to some automatic update of something that I accepted without caring too much. Python for example, or the Kernel, I have no idea so far.
Now, before trying to understand what went wrong I need to know what I changed. My question is: how can I access my recent history of updates (I usually use Yast for updating)? Is there some simple way to undo whatever I did??

Please tell me there is…
:slight_smile: Thank you in advance

prepare to die :wink:

the real answers by Xilanaz and caf4926 are two of several paths to
continued life…

another is:

restore from the full system backup taken prior to the update which was
authorized while guilty of “without caring too much”…

in other words, the the pre-update choices are these:

  1. care a lot, or
  2. backup a lot, or
  3. enjoy Russian Roulette, and
  4. be prepared to die, constantly. :wink:

A variation of that, showing more info:

Data:

rpm -q -a --queryformat "%{INSTALLTIME} %{INSTALLTIME:day}
%{BUILDTIME:day} %-30{NAME} %15{VERSION}-%-7{RELEASE}
%25{PACKAGER}
" | sort | less -S

or

pm -q -a --queryformat "%{INSTALLTIME} %{INSTALLTIME:day}
%{BUILDTIME:day} %-30{NAME} %15{VERSION}-%-7{RELEASE} %{arch}
%25{VENDOR}%25{PACKAGER}
" | sort | cut --fields=“2-” | less -S
