Description Elmar Stellnberger 2007-01-23 11:43:29 UTC

After adding "http://software.opensuse.org/download/DBUS/" as an installation source and performing an update my SuSE 10.1 installation has been totally destroyed:
ZenWorks has decided to uninstall core components like libzypp, libzypp-backend, kdebase3, hal, powersave, hwinfo and many others, because they all depend on /usr/lib/libdbus-1.so.2 which has been replaced by /usr/lib/libdbus-1.so.3.
Interestingly it did not uninstall packages depending on kdebase3 i.e. the whole KDE environment so that something in the package dependency resultion must be clearly messed!

Comment 2 Elmar Stellnberger 2007-01-23 14:06:09 UTC

The updater should probably view packages to be deleted red, fat and with 12pt! 8pt black messages are often overlooked!

Comment 3 Elmar Stellnberger 2007-01-25 15:32:28 UTC

please have a look at bug #238770, too.

Comment 4 Will Stephenson 2007-01-26 14:33:16 UTC

Whoops, I just wanted to watch this bug, not assign it to myself

Probably a wontfix though, buildservice packages are unsupported.  What concerns me is that it was so easy for zen-updater to take all newer packages known to the system as updates.  IMO it should only take patches from the update source on 'update', as opensuse-updater does.

Blindly updating with everything available in there is roughly equivalent to dd if=/dev/random of=/dev/hda, just slower.

Comment 5 Elmar Stellnberger 2007-01-26 15:15:05 UTC

It has probably been my mistake not to have a look at the uninstall list, but the examples seem to reveal certain errors in the dependency resolution:
* If it decided to uninstall kdebase3 it would have to remove Kde completely.
* It can not be true that the dependency resolution fails one minute later on exactly the same package selection which had already been accepted.

Comment 6 Elmar Stellnberger 2007-01-26 20:51:43 UTC

Aber nein, werden wir doch nicht gleich wegen ein paar Fehlern aufgeben!
und außerdem: Wenn das neue System nicht mehr leistet als das alte aber langsamer ist wieso verwenden wir dann nicht gleich das alte *?
nur ein paar kleine Hacks und alles geht wieder ...
-> gute Software fördert eben die Kreativität ihrer Anwender!

* it should only take patches from the update source on 'update'

Comment 7 Elmar Stellnberger 2007-02-08 09:30:48 UTC

Note: The updates from "http://software.opensuse.org/download/DBUS/" are very valueable since they have fixed bug 206352 (kpowersave-dbus) under Suse10.1. Moreover this update has been necessary to make the HAL-automounter work.

Comment 8 Stanislav Visnovsky 2007-02-08 09:34:58 UTC

Please, attach /var/log/zmd-backend log as well

Comment 9 Elmar Stellnberger 2007-02-08 10:45:00 UTC

The zmd-backend log is already online at bug 243494.

Comment 10 Stanislav Visnovsky 2007-02-08 11:32:23 UTC

OK. Schubi, is there anything broken in the dependency handling?
Why user is not provided with a way to fix them?

Comment 11 Stefan Schubert 2007-02-09 09:29:16 UTC

I had a look to the lofiles of  bug 243494 but I cannot see any delete request of 
e.G. ibzypp or libzypp-backend.
Elmar can you reproduce it ? If yes, please start the ZMD deamon with:
export ZYPP_FULLLOG=1; rczmd restart
So the logfiles would be more verbose.

Comment 12 Elmar Stellnberger 2007-02-09 20:39:28 UTC

They have both definitely been removed (No; this is not a joke). 
I know it because I had to reinstall them on my own.

> rug hi -a removal|grep zypp
18.01.2007 | removal | libzypp               | 1.3.2-0.9
18.01.2007 | removal | libzypp-zmd-backend   | 7.1.1.0-42.53

Persuade yourself by:
> sed -n "s#.*Removing .*package\]\(.*\)..#\1#p" <zmd-messages.log.2007-01-18
or particularly by 
> sed -n "s#.*Removing .*package\]\(.*\)..#\1#p" | grep zypp
: libzypp-zmd-backend-7.1.1.0-42.53.i586
: libzypp-1.3.2-0.9.i586

Perhaps Zenworks should stop where it has to remove itself - very reasonable.

Comment 13 Elmar Stellnberger 2007-02-09 21:28:55 UTC

  Reproduce that? You lucky having a good mood!
At least not now (From Tomorrow on I will be away).
To reproduce that I would at first have to downgrade dbus-1 (upgrade desc: bug 206352) and then perform the upgrade again just to get an unusable system. Perhaps I can do that before I wrack down my old Suse10.1-Installation to replace it by OpenSuse 10.2.
  I did not want to do so up to now because 10.1 is still working and because I would loose the proprietary addons (OpenOffice:NovellEdition, YaST-Cfg) uo. It would be cat's pajamas if you could provide them for me if I should reproduce this with ZYPP_FULLLOG=1.

Feel free to reopen the bug, if you can provide the required information.
