    apt-get Rolling back changes

    Hi;

    I did 2-3 installs/upgrades yesterday.

    Something I did changed something that broke an application I use a lot.

    Is there way to get apt-get to rollback everything it did over the past day
    ( I don't remember everything it did )

    --You need to be more specific. What broke, exactly?

    --The quick-and-dirty thing to find out what was installed is to:
    ' ls -tl /var/cache/apt/archives |head ' (you can also pipe output to "less" instead of "head" if you have a lot of packages installed on the same day. You don't have to be root for this.)

    --Post the results of that command, and maybe we can try apt-get install pkgname/stable or something.

    --Usually when upgrade breaks something, Debian fixes it right away. You might try another update/upgrade a day or so after the last one, and see if it got fixed.

    --Here is a script I use for updating my boxes (don't forget to chmod +x it) - #BEGIN /root/bin/updt
    Code:
    #!/bin/sh
    apt-get update
    apt-get -u upgrade
    #debsort
    mv -f -v ~/DEBInstalled.list ~/DEBInstalled.list.prev ; \
      dpkg -l >~/DEBInstalled.list 
    updatedb &
    ##END
    --Now whenever you get packages on your system upgraded, you can ' diff ~/DEBInstalled.list.prev ~/DEBInstalled.list ' and see what changed.

    --A final note, it is a VERY good idea to start tracking what you are doing to the system. I use a file called localinfo.dat in root's home dir, and track every new package that gets installed, every pkg that gets removed, hardware upgrades, driver updates, etc. Here's an excerpt:

    Code:
    2003.0715 + Installed pkg (mplayer-686 w32codecs)
            - Removed mplayer-686 and compiled from source (not finding codec)
    ( ./configure --enable-gui --enable-largefiles --enable-vorbis --enable-xmms
    --with-win32libdir=/usr/lib/win32
    ) -- aalib support errored out.
    
            ? Installed mplayer-skin--default-1.7.tar.bz2 into
              /usr/local/share/mplayer/Skin, but it's still not finding
              the win32 dlls.
            ! This is getting old REALLY fast.
            + Installed mplayer--qt6dlls.tar.bz2, mplayer--qtextras.tar.bz2
    
            + :) Now it works - but it keeps crashing at the end of QT videos. :(
    
            ++ Changed proftpd.conf for better security (ServerIdent.)
    
    2003.0805 - Removed proftpd (conf file changed)
            + Installed pkg vsftpd
            + Restored /etc/ftpusers file (deleted when proftpd went)
            + Updated stopsvcs
    
            + Installed pkg bittorrent
    
    2003.0817 + Renamed .xinitrc to .xinitrc-manual and updated .bashrc,
            since the way it was had broken plain startx
    
            + VNC on this box works diff than p233 - the ~/.vncrc is used here.
    
            + Updated NVIDIA driver to 4496.
    
    2003.0821 + Installed mozilla-browser-snapshot with synaptic
            + Installed pkg aptitude

    Excellent point.

    I used apt-get to upgrade icewm from 1.2.7 to 1.2.11. In the process it looked like upgraded some C libraries ( next time I will pay attention ) and prompted me for a bunch of preferences. It looked like most were for icewm, but I am not sure.

    After the upgrade when I would go run Visual SlickEdit ( an editor ) I would get Segment Fault messages.

    Chances are you hit the limitation of dpkg/apt-get and may not be able to do what you want. I have come across similar scenario before like the following :

    I need to install a newer package that needs libc6(the core of the whole GNU tool set and almost everything) which would upgrade from 2.2.5(woody) to 2.3.1(sid/sarge). Once this is done, there is no way it can go back to 2.2.5 as apt-get would remove almost everything(including dpkg/apt-get itself) that use this libc6.

    I don't know what your affected packages is but if it is some library(most likely) it is not easy. the only thing I can think of is to do a :

    1. dpkg --get-selection > current
    2. don't include the source repository that 'upgrade' your affected package
    3. dpkg --set-selection < current
    4. apt-get dist-upgrade

    and hopefully it would restore the whole thing, but I am not sure given the design of dpkg.

    There is, but I don't want to shell out the money for an upgrade until I can see if I can fix my system and if an upgrade will solve the problem.

    Yes, I have done the free of charge editors. Emacs used to be my life.

    The dates are a bit off, I think because I had soem clock issues that I did not bother to fix.

    The libs listed look familiar. apt-get got them for me when I upgraded to icewm 1.2.11 out of unstable( I down graded icewm back to icewm 1.2.7 which I found in test ).


    Should dpkg _P these libraries and install the version from test or will I be getting myself into more hot water?

    I found my own answer:

    1. get the name of the previous package
    2. use an '=' in place of space in the package name
    3. put the package name in a normal apt-get install command:

    $ apt-get install libc6=2.2

    I was able to roll stuff back and get my editor working without paying for an upgrade

    --That's cool; I have to remember that for next time. You should go into ' aptitude ' and put a Hold on the packages that broke before so they don't get upgraded again.
