[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
In my grub menu.lst file, the following line appears at the end of the file: ### END DEBIAN AUTOMAGIC KERNELS LIST Thus all the title, root, kernel, initrd definitions appear above this comment. I looked at some old menu.lst files, and some of those do have definitions between the above comment and the end of the file, as well as definitions which are presumably within the AUTOMAGIC KERNELS LIST section. What I am trying to discover is how (and why) the UUIDs were changed, and what I can do to avoid this happening again. -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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
[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
If you can attach your entire menu.lst we can probably see what has happened. I'm guessing when you moved your disk from your old pc to the new one and changed the kernel entries, you didn't update the automagic bit, or it has gone missing some how. I am then guessing a kernel update was installed which triggered a regeneration of the menu.lst and made it incorrect (although correct for your old pc) -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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
[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
Attached is my menu.lst file. Here is what I did: 1. I installed a new disk in my computer alongside my old disk. 2. I partitioned the new disk and formatted the partitions. 3. I mounted the new disk's partitions and copied files into them. 4. I edited the fstab on the new disk's root partition so that the UUIDs as reported by vol_id were correct. 5. I edited the menu.lst on the new disk to use the new disk's UUIDs. 6. I edited device.map, ran grub-install, and then restored device.map (since grub won't install on the new disk otherwise). 7. I then powered off, removed my old disk and made my new disk the primary disk. After doing all this, I booted and was able to work normally until a kernel upgrade came along a few days later. I had powered off and on several times during this period. The structure of my menu.lst file has remained the same throughout the switch from my old disk to my new disk, as far as I am aware, but I obviously changed the UUIDs as described above. I don't understand why the kernel upgrade overwrote menu.lst with old UUIDs which were no longer in the file. It's possible I did something wrong. If so, the right way of doing an upgrade like this should be documented. I used the how to document here (using discretion and prior experience where LILO was mentioned instead of grub): http://www.storm.ca/~yan/Hard-Disk-Upgrade.html ** Attachment added: The current menu.lst http://launchpadlibrarian.net/22960051/menu.lst -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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
[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
H, everything looks good as far as I can see. These two lines:- # kopt=root=UUID=118bcea1-999a-4e47-a192-2cc5fb2982be ro # groot=(hd0,0) Are the ones that determine how grub will recreate the menu.lst when needed. You shouldn't run into this problem again and the menu.lst should stay the same. Could you try running:- sudo update-grub Which will update your grub file like if you have just installed a new kernel. Check the menu.lst afterwards, if it all looks good then I think your problem is solved. -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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
[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
OK, I ran update-grub and it appears that no changes were made, so I suppose that the configuration is stable.

[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
I believe the problem you are experiencing is that you have not updated the Automagic Kernels List in the grub config. Every time your kernel gets updated, it uses these settings to re-generate your list of kernels. If you edit the Automagic Kernels List which is Located just above the list of kernels, it should solve your problem. Note the list is meant to be hashed out, in that section double hashes form comments. ** Changed in: ubuntu Status: New = Incomplete -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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
[Bug 321603] Re: Unable to boot Ubuntu server after update/upgrade
This bug seems to be similar to my own experiences, so I'm adding this comment to it. After having my system upgraded yesterday (2009-01-30) using the package linux-image-2.6.22-16-generic_2.6.22-16.61_i386.deb, I found today that it was impossible to boot my computer. Upon selecting any entry in my grub boot menu, I got Error 15: File not found. I looked at the commands in the grub command editor (by pressing E in the boot menu screen) and saw that the root definition was incorrect and the UUID for the kernel definition was also incorrect. These are the definitions I saw: root(hd0,5) kernel /boot/vmlinuz-2.6.22-16-generic root=UUID=20ae8580-c8c7-4c16-a436-181b9e38a3a7 ro quiet splash initrd /boot/initrd.img-2.6.22-16-generic I worked around this by setting root to (hd0,0) and by replacing the UUID=... with /dev/sda1, removing the quiet and splash options so that I could actually see what happens, rather than seeing the Kubuntu progress bar and then seeing absolutely no detail when switching to text mode. Upon looking at /boot/grub, I saw that menu.lst and menu.lst~ were both updated yesterday and both were the same, so the update didn't preserve the old contents of menu.lst. I have now changed the contents of menu.lst back to what it was before. I have recently switched hard disks in my computer, and the layout of the partitions is different to those on my previous disk (which did use (hd0,5) as the root partition, along with the UUID shown above). However, I made sure to change menu.lst to use the new, correct values, and I had successfully booted several times before this error occurred today. It might be the case that some other file is used to retain details of the root partition and that the update scripts populate menu.lst with values from this other file, but it is very bad that the scripts just discard any existing copy of menu.lst, making an identical duplicate of the new, incorrect file, and if such special files with disk information then these should be documented somewhere. ** Tags added: grub menu menu.lst -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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

Of course, the last part of my comment should read, if such special files with disk information *exist* then these should be documented somewhere. -- Unable to boot Ubuntu server after update/upgrade https://bugs.launchpad.net/bugs/321603 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
