my 1st try to upgrade from 11.3 to 11.4 using "zypper dup" breaks like this:

...
Removing libknotificationitem-1-1-4.3.5-0.1.1 [..done]
Removing liblouis0-1.7.0-2.2 [..done]
Removing liblzma0-4.999.9beta-3.7 [..done]
Removing liblzma0-32bit-4.999.9beta-3.7 [.error]
Removal of (42614)liblzma0-32bit-4.999.9beta-3.7.x86_64(@System) failed:
Error: Subprocess failed. Error: RPM failed: rpm: error while loading shared libraries: liblzma.so.0: cannot open shared object file: No such file or directory

Abort, retry, ignore? [a/r/i] (a): .done]


fortuneately this was running in a chrooted copy of 11.3, so I was able to copy the missing liblzma.so.0: back to the to-be-upgraded tree -- otherwise this is a show stopper for "zypper dup" style upgrades:-((((

rest of the upgrade when smooth but again quite slow (4.5 hours for 3754 packages from DVD-x86_86 with DSL-2k for the remaining packages), although so far I did not have time to try booting the new system, so the final voting has to wait a bit;)
