[Bug 940396] Re: lucid -> precise main all failed to upgrade: dpkg: dependency problems prevent configuration of kde-runtime

[Michael Vogt]

I can finally reproduce this now with the lp:~mvo/+junk/test-case-
lp940396 branch and the lp:~mvo/apt/debian-experimental2 branch:
"./run.sh /path/to/debian-experimental2/build/bin/apt-get" triggers it
for me.

There are various workaround:
- add versionized dependency of libsmbclient (>= 2:3.6.3) to kde-runtime that ensures libsmbclient is unpacked early
- add breaks to kde-runtime against libsmbclient (<= 2:3.6.1) (just like libkrb5-3)

But of course those are workaround not fixes.

One fix that works for me is to do:
=== modified file 'apt-pkg/packagemanager.cc'

 			List->Flag(Pkg,pkgOrderList::Loop);

+		     SmartUnPack(BrokenPkg, true, Depth + 1);
 		     if (PkgLoop == false)
 			List->RmFlag(Pkg,pkgOrderList::Loop);
 		  }

So essentially calling unpack with immediately configure to ensure that the package is fully ready early. But that is
slightly risky as it will have side-effects beyond this one bug. It does work for me though.

I'm looking into more possible solutions.
