I think I have experienced this problem upgrading from 'hardy' to 'intrepid'.
It seems that the grub update step isn't synchronised with the installation of the new kernel, and the generation of a new initramfs. In my case, I ended up with a menu.lst that listed the new kernel, but did not have a corresponding initrd line for it. The menu.lst was generated at a time when the kernel image was there, but the initramfs had not yet been created. The new kernel would not boot. Fortunately an old one would. -- menu.lst not updated after kernel update https://bugs.launchpad.net/bugs/290140 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
