When using the in-place distibution upgrade method from an older openSUSE distribution as described here: http://de.opensuse.org/Upgrade, the distribution upgrade will fail.

This seems to be due to liblzma package naming scheme haveing been changed. Thus, liblzma0-4.999.9beta is being removed first, rendering zypper itself useless. The distribution upgrade cannot be continued and leaves the system in an undefined state.


Reproducible: Always

Steps to Reproduce:
Use the instructions on the page http://de.opensuse.org/Upgrade

Actual Results:  
During the "zypper dup" phase:

Expected Results:  
liblzma should have been upgraded instead of being removed. There should be compatibility libraries in the new liblzma package and it should habe the same name as the old one.


The changes in liblzma seem to have caused many problems, see also bugs #669205 and #677549.

Although this feature is not officially supported, this bug causes a major problem for people who want to upgrade over the network (like rented root servers). It will most likely be problematic in an upcoming SLE release and should be fixed.
