I don't think you should upgrade grub. At least not yet. As I can see from your menu.lst file there is no entry for the previous kernel (2.6.31-14). Is this because you manually edited the file? What is the content of your '/boot' directory?
Although I don't underestimate the error's significance, I think that maybe it's not reproducible. -- package linux-image-2.6.31-15-generic 2.6.31-15.50 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/487096 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
