[master] upgrade problem with libcupsys2: "E:Error, pkgProblemResolver::Resolve generated breaks"

The workaround is to remove the package "libcupsys2" that is no longer needed and replaced with licups2.

So one way of fixing it is to remove the "Provides: libcupsys2" from libcups2, that will ensure that the upgrade continues. If we add a old fashioned transitional package that will ensure it keeps working.

I uploaded a slightly different version that does not use a transitional pacakge but instead simply conflicts/provides/replaces and that is doing the trick for me in my test-setup.

I committed the change to the Debian bzr, so the next sync to precise will have it.

Hello Michael, or anyone else affected,

Accepted cups into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

This bug was fixed in the package cups - 1.5.0-9

---------------
cups (1.5.0-9) unstable; urgency=low

  [ Till Kamppeter ]
  * debian/patches/do-not-suppress-inputslot-setting-with-empty-ap-d-inputslot.patch:
    CUPS adds the option setting "AP_D_InputSlot=" to every job. This overrides
    the InputSlot option and so the InputSlot setting and even the default
    setting for InputSlot in the PPD get never used, rendering InputSlot
    useless (LP: #872527).
  * debian/patches/cups-avahi.patch: Updated patch from upstream (Red Hat)
    to fix crashes of the CUPS daemon when using the timeout function call
    functionality (LP: #860691, LP: #860498).

  [ Martin Pitt ]
  * debian/local/apparmor-profile: Also allow cups to map libraries under
    /usr/local/. (LP: #860765)
  * cups-avahi.patch: Make sure to guard against retrying the Avahi connection
    whilst already doing so. Thanks to Tim Waugh for the patch! (LP: #877967)

  [ Michael Vogt ]
  * debian/control: Add Conflicts/Replaces: libcupsys2 to ensure that the apt
    resolver can calculate the upgrade in a multiarch scenario where a old
    libcupsys2 package is installed (LP: #874835)

I think nspluginwrapper was my problem. I had a canon mp600 printer install that I used a i386 configuration script to install, that included installing a nspluginwrapper that I don' t know the source of. I had a system that was working fine, then I tried to upgrade that didn't work. I did a clean install not I have a system that is highly unstable. I am going back to 11.04. I may try to upgrade again in a few months. If I still have problems I am going back to Fedora.

SRU verification for Oneiric:
I have reproduced the problem with cups 1.5.0-8ubuntu2 in oneiric-updates and have verified that the version of cups 1.5.0-8ubuntu3 in -proposed fixes the issue.

Marking as verification-done

This bug was fixed in the package cups - 1.5.0-8ubuntu3

---------------
cups (1.5.0-8ubuntu3) oneiric-proposed; urgency=low

  * debian/control:
    - properly Provides/Conflicts/Replaces: libcupsys2 to ensure that
      the apt resolver can calculate the upgrade in a multiarch scenario
      where a old libcupsys2 package is installed (LP: #874835)

Hi, I want to upgrade from 11.04 to 11.10. I think I have the same issue. As I read, resolution of the problem is to install cups 1.5.0-8ubuntu3. How can I install cups 1.5.0-8ubuntu3 on 11.04 amd64? I enabled natty-proposed but newest available version is cups 1.4.6-5ubuntu1.4. Thx in advance.

Hi!

It seems like ubuntu has updated central packages. A week after I got the sollution, I just reexecuted the upgrade process and it installed ok.

Some mismatch with my printer driver for my multi function Canon printer as result, but I haven't tried to fix it.

Good luck with Your upgrade!

I may jumped the gun, but since that I needed the machine urgently for work, and since that at some point my gnome didnt work. i moved to 32 bit. Ubuntu is running okay now it recognized all of my 8gig ram and most of the problems are gone.
