I figured out why is this happening. When I first submit the bug report above, I am using a motherboard with VIA C3 Samuel 2, which is a 686-class CPU but WITHOUT the "cmov" instructions.
Now I have upgraded to a new motherboard with VIA C7-D 1.5Ghz, which is a 686-class CPU WITH "cmov" instructions, now the problem gone away. So I suspect it is another "C3 cmov" problem causing Segmentation fault during installation of openjdk. Goggling with "VIA C3 cmov", you would able to find out more information concerning this cmov problem. -- package openjdk-6-jre-headless 6b09-0ubuntu2 failed to install/upgrade: https://bugs.launchpad.net/bugs/222339 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
