Hello, list. I just decided to upgrade my Ubuntu Feisty system to Gutsy and run into following problem after upgrade. Dpkg failed to configure libc6 with the following error message: Setting up libc6 (2.6.1-1ubuntu9) ... Processing triggers for libc6 ... ldconfig deferred processing now taking place Bus error (core dumped) dpkg: subprocess post-installation script returned error exit status 135 Running ldconfig manually returns the same error message from bus. It actually prevents me from doing any further update or upgrade for my system since aptitude says that not all packages are properly configured since dpkg exited abnormally and I have to run dpkg --configure -a. And after running that command I get the message shown above. Any clue to the solution would be highly appreciated. Sergei.
