[lucid] mozilla-packagekit cannot be installed with firefox 3.5

Looking through the changelog, this plugin is not compatible with firefox 3.0 because of the level of xulrunner.

Am I correct in thinking that it should be "Conflicts: firefox-3.0" as it has the wrong level of xulrunner, as opposed to "Breaks" which implies that firefox-3.0 must be deconfigured first

From the Ubuntu Policy document:
When one binary package declares that it breaks another, dpkg will refuse to allow the package which declares Breaks be installed unless the broken package is deconfigured first, and it will refuse to allow the broken package to be reconfigured.

Should this simply conflict with firefox-3.0 and only recommend other browsers?

Is there are particular reason you need to install firefox-3.0?

We currently do not support installing two version of firefox simultaneously on a system.

Also is this with Ubuntu 10.04?

Not at all - in fact I do NOT want 3.0, but 3.5
However this does not seem to work as 3.5 provides 3.0 and the packagekit plugin breaks 3.0 and it wants to remove it

I think the issue is simply that the package should conflict with 3.0 instead, as making this change in a local copy of the package allows it to install fine and without the above attempts to remove 3.5

The above was on lucid

On maverick it appears to work find as the "firefox" package (no 3.0 or 3.5, just firefox which is 3.6) does not provide "firefox-3.0" and so there are no problems at install time

Is this fix going to be backported to Lucid?

For engineering,

This issue has been fixed in Maverick, but, the customer would also like to have this ported to Lucid. They still deploy Lucid pretty widely.

The issue here is that mozilla-packagekit declares a breaks on
firefox-3.0, which is a transitional package in Lucid to migrate Hardy
upgraders to the new package. In addition to this, the Lucid firefox
package declares a Provides on firefox-3.0, to ease the transition for
other things in the archive depending on firefox-3.0.

Because the Breaks is unversioned, mozilla-packagekit won't install
until firefox and firefox-3.0 (if it is installed) have been
deconfigured. We should fix this by declaring a versioned Breaks
instead, which seems fairly non-invasive.

Closing main task, reportedly fixed in maverick.

Looks like http://bazaar.launchpad.net/~packagekit/packagekit/ubuntu-maverick/revision/223 is the fix for this? Looks fine to backport to lucid.

Martin,

Yes. Unless someone has anything different to add, that's the fix that IBM would like to see ported to Lucid.

Here is a debdiff for Lucid

That diff looks like it should fix the issue

Accepted packagekit into lucid-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!

Fix works as expected, thanks!

This bug was fixed in the package packagekit - 0.5.7-0ubuntu2.2

---------------
packagekit (0.5.7-0ubuntu2.2) lucid-proposed; urgency=low

  * Fix LP: #606910 - in mozilla-packagekit, don't declare Breaks on
    firefox-3.0, as this is provided by firefox now (to ease transition),
    and prevents mozilla-packagekit from being installed along firefox
    - update debian/control
