Hi there, I just upgraded my TW (20150319) installation to TW (20150327) and faced this: Problem: strace-32bit-4.10-1.1.x86_64 requires libunwind-x86.so.8, but this requirement cannot be provided uninstallable providers: libunwind-1.1-12.1.i586[oss.local] Solution 1: Following actions will be done: install libunwind-1.1-12.1.i586 despite the inferior architecture architecture change of libunwind-1.1-12.1.x86_64 to libunwind-1.1-12.1.i586 architecture change of strace-4.10-1.1.x86_64 to strace-4.10-1.1.i586 install strace-4.10-1.1.i586 despite the inferior architecture Solution 2: do not install strace-32bit-4.10-1.1.x86_64 Solution 3: break strace-32bit-4.10-1.1.x86_64 by ignoring some of its dependencies It appears to me that libunwind-32bit is missing => <https://bugzilla.suse.com/show_bug.cgi?id=924827> Cheers. l8er manfred
