I had this same issue as I was trying to perform regular updates in Jaunty.
Based on the comments here, I changed one line from: # updatedefaultentry=true to: # updatedefaultentry=false The update succeeded this time. I restored the original line afterwards. It seems to be related to certain entries related to a 160GB IDE hard disk that insists on being the boot drive if it is connected. My other hard drives are SATA. I have attached the output from fdisk -l. All of my Linux partitions are reiserfs, except for /dev/sdc5, which is ext2. sda = SATA sdb = SATA sdc = IDE The entries in menu.lst: boot hard drive that I had removed. I think, but can not guarantee, that this is the first kernel update since I removed the hard disk permanently. I had used grub to install to both hard drives, knowing that I would be experimenting with the removal of the one, but still wanted the computer to boot with only the first hard drive connected. I am willing to help test if anyone has suggestions. ** Attachment added: "output of sudo fdisk -l" http://launchpadlibrarian.net/48937247/fdisk-l.txt -- update-grub fails when default is "saved" https://bugs.launchpad.net/bugs/193439 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
