SP2: Broken patches & newer version installed than available

[zugenmaier]

Hello,

I updated to SLES 10 SP2, and now I have "broken patches". In the graphical GUI of Yast2, they are marked with an exclamation mark in a triangle (road sign). The cli says "this patch is broken".
In the "add/remove software" GUI, some software packages are marked red, and the installed version is newer than the available version. That is the state after my own efforts to solve the problem. Before that, it was the other way round, and the line was marked blue instead of black. If I try to "update" these software-packages, than Yast says, it cannot resolve the dependencies and it wants to deinstall all dependent packages.

CONCLUSION: System is NOT up-to-date!
found SLE-10-x86_64-SP1 + "online updates"
expected SLE-10-x86_64-SP2

I have a test system, where the "broken patches" problem does not appear. I experimented a bit, but I only worsened things. ZMD is now permanently refreshing ...

I cannot find anywhere a reasonable description of the several SUSE updater services around ... Can anyone help?
