    Default What's the best way to go back from 13.1 to 12.3?

    Hi, I've spent weeks trying to get everything working again since upgrading to 13.1 from 12.3 using the 13.1 x86_64 cd. My sound no longer works, mythtv no longer works, and the only way I can get the system to reboot or shutdown is by using the reset button or power switch, because the system hangs unless I boot to the 3.7.10 kernel from 12.3. I've submitted bugs but the future doesn't look good for getting them fixed anytime soon since TV cards are a low priority. I just want to have a working system again without starting over with a fresh install of 12.3

    Thanks for any help.

    Hi, for starters and to help the helpers:

    How did you upgrade? What method e.g zypper dup?

    What desktop did you have on 12.3 e.g KDE, Gnome, or other?

    Please post links to your bug reports, so helpers can read them to save time. Even so, there will probably be more questions.

    We can try to help you solve the issues, but going back is next to
    impossible.

    The easiest way is to recover from backup. No kidding.

    Then you could try a zypper dup backwards, but it can fail or leave you
    an unusable system or broken who knows where. Then it might just work...
    nobody can know.

    Or, reinstall.


    So instead just post here links to the forum threads where you asked for
    help on each of those separate issues.

    I also would like to know how exactly did you upgrade from 12.3 to 13.1.
    Which CD, the netinstall CD? That's the only one I know. Then what did
    you do?

    Hi Robin,

    I typed CD when I meant DVD. I downloaded the 13.1 x86_64 DVD (I used to buy the boxed DVDs, but the only one available now seems to be the German one).

    I booted from the 13.1 DVD and selected upgrade from the menu. That's when I descended into Hell.

    I have posted a bug on bugzilla.novell.com (Bug 876806), where I was directed to post a bug on bugzilla.kernel.org (Bug 75821). In the meantime, I no longer have sound, (probably from installing 3.14.2 and 3.7.10 per the request from wolfi323). That was working before the upgrade.

    I am using the KDE desktop.

    I was planning to just copy my /home directory to another location, boot from the 12.3 dvd and "upgrade" the 13.1 partition. Then I will copy my /home directory back.

    At this point, I don't care if I have to reinstall/reconfigure apache2, mythtv, libreoffice, and audacity. That part is easy compared to the frustration that 13.1 has put me through.

    At this point, I think 12.3 is going to be my last version. Mythtv has become a backwater as far as openSUSE is concerned, so there is not likely to be a kernel fix any time soon. I understand that, which is why I would rather go back to something that works.

    If it was my system, I would also try options in the following order:

    • Restore from a partition backup (preferably clone where only used blocks are saved), if you have one.
    • Remove unwanted kernels (in case zypper dup doesn't). Change repos back to 12.3 versions. Consider just enabling the four main openSUSE repos, but that means extra update(s) for additional repos later. Perform "zypper dup", it might work.
    • Clean install (formatting root partition) from 12.3 original media. The most work, to change settings, and reinstall applications. The 13.1 KDE settings in /home (e.g. ~/.kde4/) might cause problems. You can delete those .kde4 settings and logout/re-login, but you will then need to repeat your previous customizations.

    Good luck, 12.3 is a pretty good release (I was using it recently until upgrading it online to 13.1).

    Just for your information, you have written a wrong bugzilla.novell.com bug number in your bugzilla.kernel.org bug report.

    I have corrected my entry in bugzilla.kernel.org in a comment. Thanks for noticing, wolfi.

    Thanks for your help, consused.

    I can't do the first option (no partition backup), but the second option looks like it should work for me, and the third option may be useful, too.

    I think I will be buying an external hard drive for backups due to the lessons learned from updating to 13.1.

    Hi again,
    since I never used zypper dup before, I looked up the procedure in the SDB. Here is what I have done so far:
    Code:
    As an example, we will be showing upgrade from 12.3 to 13.1 here:
    
    • Take a look at all repos you have
    • zypper lr and remove all third party/OBS repos you no longer need#
    • zypper rr <alias>
    • Change all remaining repo URLs to the new version of the distribution (needs to be run as root)#
    • cp -Rv /etc/zypp/repos.d /etc/zypp/repos.d.Old (for a backup copy), then:
    • # sed -i 's/12\.3/13\.1/g' /etc/zypp/repos.d/*
    In the last step I changed it to:

    sed -i 's/13\.1/12\.3/g' /etc/zypp/repos.d/*

    The result is:

    Code:
    # grep 12.3 ./*
    ./download.opensuse.org-Stable.repo:baseurl=http://download.opensuse.org/repositories/LibreOffice:/Stable/openSUSE_12.3/
    ./ftp.gwdg.de-suse.repo:baseurl=http://ftp.gwdg.de/pub/linux/packman/suse/openSUSE_12.3/
    ./openSUSE-13.1-1.10.repo:[openSUSE-12.3-1.10]
    ./openSUSE-13.1-1.10.repo:name=openSUSE-12.3-1.10
    ./packman-essentials.repo:baseurl=http://packman.inode.at/suse/openSUSE_12.3/Essentials/
    ./packman-multimedia.repo:baseurl=http://packman.inode.at/suse/openSUSE_12.3/Multimedia/
    ./repo-non-oss.repo:name=openSUSE-12.3-Non-Oss
    ./repo-non-oss.repo:baseurl=http://download.opensuse.org/distribution/12.3/repo/non-oss/
    ./repo-oss.repo:name=openSUSE-12.3-Oss
    ./repo-oss.repo:baseurl=http://download.opensuse.org/distribution/12.3/repo/oss/
    ./repo-update-non-oss.repo:name=openSUSE-12.3-Update-Non-Oss
    ./repo-update-non-oss.repo:baseurl=http://download.opensuse.org/update/12.3-non-oss/
    ./repo-update.repo:name=openSUSE-12.3-Update
    ./repo-update.repo:baseurl=http://download.opensuse.org/update/12.3/
    Does that seem reasonable?

    I am not ready to do the zypper dup yet, just in case some more information is needed for the bugs I entered, but since they are relatively low priority, I am not going to wait too long.

    In the meantime, I copied /home/alfredr/* to a different drive.

    Thanks again for your help

    Well, that grep only shows the lines that contain 12.3, so doesn't really help to verify.

    Just run "zypper lr -d" and check that all the URLs have 12.3 in them.

    What the grep produced does look reasonable, only one note:
    you don't need packman-essentials and packman-multimedia, remove them. You seem to have the full Packman repo as well anyway, which of course includes everything from essentials and multimedia.

    But again, that grep output isn't really helpful. It doesn't even show which repos are enabled and which are not.
