Ubuntu Installation :: Natty Upgrade - LVM Grub (No Such Disk)
May 5, 2011
I've had this problem on a couple of Ubuntu server upgrades and am keen to get to the bottom of it. Basically, with an Ubuntu 10.10 server installtion where LVM has been used, running through the do-release-upgrade process works perfectly until the reboot stage. Then grub complains with "no such disk" and dumps me out to the grub shell. From here, I can see (from ls) the following:
Code:
(hostname-swap_1) (hostname-root) (hd0) (hd0,5) (hd0,1) (fd0)
I can enumerate the filesystem on (hd0,1) which seems to contain the /boot filesystem and the filesystem on (hostname-root) seems to contain the / filesystem.
If I execute:
Code:
linux=(hd0,1)/vmlinuz-image-2.6.38-8-server root=(hostname-root)
initrd=(hd0,1)/initrd.img-2.6.38-8-server
boot
It boots, but into busybox saying that the target filesystem doesn't have requested /sbin/init.
I upgraded to Natty yesterday and my system boots into it ok but I don't get a grub menu (and so no other options like recovery mode which I really need right now). I tried purging grub and re-installing it on /dev/sda but still no joy. Here's the info from the Boot Info Script. I've also tried uncommenting GRUB_GFXMODE=640x480 in /etc/default/grub but that doesn't help. How I can get the menu back?
Code: Boot Info Script 0.56 from 8 February 2011 => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of the same hard drive for core.img. core.img is at this location and looks for (,msdos1)/boot/grub on this drive. => Windows is installed in the MBR of /dev/sdb .....
Devices which don't seem to have a corresponding hard drive: sdc StdErr Messages: unlzma: Decoder error unlzma: Decoder error
I've tried to use that thread to help but to no avail, i tried to use this:
[URL]
BUT I CAN'T OPEN A TERMINAL!!! as i am at a point where the screen says: Continue to wait, press S to skip or M for manual recovery. so if i run this command : gksudo gedit /etc/fstab my computer whines about there being no way to show this on the screen, I have tried this:
Use a non-graphical editor, like emacs or vi. Try Ctl+Alt+F3 -- you should get a login prompt. Login to an account with admin privileges (like, the first account you created, for example), and then type 'sudo vi /etc/fstab'; that will open /etc/fstab in the vi editor. Make your changes, save them, exit the editor, reboot... but if you're not used to working with a non-graphics-based editor, you'll have a bit of research to do. It's not hard, though, just tedious.however i have not managed to make it work.
My current setup was: 4 x 500 gb hard drives in (software / onboard controller) Raid 10 (1 +0) with Windows 7 x64 as the primary OS 1 500 gb hard drive with Ubuntu 10.10 installed
After upgrading to Ubuntu 11.04 Beta, I hit the Grub Error. I have removed the 5th HDD but still getting it on boot into Windows 7. I am currently in the process of copying all files from my raid via a 10.10 flash drive boot (fortunately was able to mount my raid's partitions).
My ubuntu desktop died yesterday. I rebooted my computer in like 1 month and after grub, the screen is all black and it stays there... forever. So I decided to see if the problem persists or not when I completely upgrade my ubuntu to the latest version. So I downloaded the latest ubuntu iso from the site, burned it, and booted from CD and I see several selections to choose from the menu list. The second one was "Install Ubuntu". What I'm worried about is I don't know whether selecting 'Install Ubuntu' will erase all my previous data, or there will be an option to upgrade Ubuntu without erasing all the data. Is it safe to install from the live disk? Will my data be safe? Is there any way to upgrade my Ubuntu on the HD to the latest Ubuntu from a live disk?
I have successfully upgraded from 10.10 to 11.04, computer was rebooted and I got working Ubuntu Natty. I did not altered any settings and switched computer off. When I tried to boot computer today I got Ubuntu load screen, but OS does not load properly (only load screent, startup sound and that's all).I am able to load terminal as root. How can I troubleshot my problem?
I've just upgraded my Mythbuntu box to Natty. Now I have a completely unusable system due to Xorg taking 70% of CPU. Mouse movement is possible and I can just type but that is about it. Using MythTv is impossible.I'm running a standard mythtv build with the xfce desktop how to fix this one as it has rendered my PVR system impotent.
Story: Installed 11.04 Natty Narwal from a live cd on my 2 year old HP Elitebook. The installation completed successfully according to the Live Session. I restart... Quote: GRUB Loading stage1.5 GRUB loading, please wait... Error 15
I have 2 other operating systems on the hdd, that I was previously managing with grub which was stored in the boot directory of Ubuntu 9.04 (on the partition that I formatted to install 11.04) What I have on hand:
I browsed on internet to find how to upgrade to 11.04 and find the answer.Press Alt+F2 and enter the command update-manager -dAfter authentication, the manager showed the updates and at some point of time, I got the following error.
---- E: Encountered a section with no Package: header E: Problem with MergeList
I just upgraded to Natty and some images display shifted colors, e.g. bright purple instead of yellow and bright green instead of whatever there used to be. Some images also show properly. I attached a screenshot of a bit of Thunderbird where the bug is visible. Does anyone have any idea what is wrong, or how to diagnose the problem properly? EDIT: and, to make this even more interesting, the attachment I made to the forum displays even more ridiculously once it has been attached - I'm attaching a screenshot of that, too. (although right now I have no idea what it looks like on a working machine)
EDIT2: To reiterate the problem: apparently, Firefox and Thunderbird rotate colors in indexed images for some reason. I am trying to find a way to fix this, with no luck so far.
After upgrading my laptop from 10.10 to 11.04 I can no longer connect to my home wi-fi. It was working flawlessly for months before the upgrade. The network manager just keeps spinning and nothing happens.dmesg output just keeps showing this over & over again:
When I upgraded my 64bit System76 machine to Natty, I received an error message that initramfs-tools had failed to be upgraded properly. Nonetheless, when I restarted everything seemed to work as it was supposed to.However, every time I do an update the problem with initramfs-tools recurs. I get the following error message:
Processing triggers for initramfs-tools ... update-initramfs: Generating /boot/initrd.img-2.6.38-8-generic Syntax error at or above line 20 in file '/etc/lilo.conf'
Successfully upgraded to 11.04 over the weekend, and all seems to be working well. The only issue I've got is with the grub menu. I used to be able to run:
sudo gedit /etc/default/grub followed by: sudo update-grub
after kernel updates, in order to change the default OS to boot (I've been dual-booting Ubuntu and xp for several years now).
If I use the super grub disk I can get to my ubuntu partition otherwise my windows partition boots automatically. I spent over an hour in the community documentation using the live cd to reinstall grub and nothing has fixed it. I think that grub is installed and the windows bootloader is just taking precedence.
In previous versions, there was an 'advanced' button where you could select NOT to install grub. I can't find that in the latest Natty release iso's. Is it no longer an option? And if not, WHY? I find myself reloading Natty quite often on a test partition to play with various parameters in my attempt to get it working as needed. But I'd really prefer to have the option to no reload grub.
I have a system running om vmware esxi with suse 9.3 i did an inplace upgrade to 10.2. i got the follwoing error during upgrade error occurred while installing grub (version 0.97) error 21 disk cannot be found. I ignore this error and the upgrade went fine. after a reboot the server works pretty fine. Except one thing GRUB.. i cannot install it on this system. i want to install grub on this system.
X is working, I get a desktop, all updates are current, just no Unity menus/window/widgets/whatever, blank desktop with single mapped network folder and no working keyboard shortcuts after initial login. I upgraded on Alpha 2 and it ate my desktop, never has given it back for 3 months. I assumed eventually the upgrades would fix it. Looked into ditching Unity and doing GDM, but thought I'd wait it out, ran dpkg-reconfigure unity and it did nothing, can't find any relevant errors in the logs, where should I be looking and/or what should I be doing? Running lots of servers on this box and have dual-boot, otherwise I'd probably torch it and start over.
If I just upgrade my 10.10 to 11.04, will it replace gnome with unity? I tried unity before and it is not satifying because it is not customizable, I feel I have less options and less power over what my interface looks like and how it behaves. Same case with gnome3.I'm wondering if when I upgrade to Naughty will I have to go through a lot of messing around with packages and configuration files to get back to gnome2 ? Do we have an option when we upgrade to choose between Unity, Gnome2 and Gnome3?
So before natty, firefox 4 interface fonts matched the rest of my apps, but now they are huge! See the screen-shot to see what I mean. Anyone know how to get them to match again?
I think some of the browser fonts changed as well, but I know I can change them in the options menu.
I was running Ubuntu 10.4 netbook version (with Gnome) on my Dell Inspiron 910 and yesterday it told me there was an upgrade available, to Natty. I followed the links, did the download, and left it to install overnight. When I got up today, it said it had a problem, because an application was using a file it needed. I thought I had closed everything before I started the process. I acknowledged the message, and proceeded to restart.
I ended up with the standard 10.4 Ubuntu screen, but with no tool bars, status bars, or anything. Just the wallpaper. Keyring login came up and I signed in, wireless said it was connected. So it looks like things are working, just no UI as such. Poked all the screen edges with the mouse, but nothing popped out.
Ctrl><Alt><Del> brought up the logout screen, and if I clicked on Help, I could ultimately get Firefox to run. (Note: the Help screen talks about Gnome, but it had the new popout scroll bars).
If I hold down <Shift> on startup, I get the GRUB menu. I am running linux generic 2.6.38-8 , but I am not sure where to go from there. Running dpkg didn't help.
I upgraded to natty on release day and everything went fine, but about three days ago when I went to update my sources, I get this: Code: sudo apt-get update Code: W: Failed to fetch [URL] Sources 404 Not Found W: Failed to fetch [URL] Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.
I've looked through the forums, but similar problems are always tied to the mozilla repo, not this one. It seems important, so I'm not sure if I should just delete it or what. My sources.list looks like this: Code: # deb cdrom:[Ubuntu 10.10 _Maverick Meerkat_ - Release i386 (20101007)]/ maverick main restricted # See [URL] for how to upgrade to newer versions of the distribution. deb [URL] natty main restricted deb-src [URL] natty main restricted ## Major bug fix updates produced after the final release of the distribution .....
I was going to pull the trigger and do the "natty" upgrade. Before I do I had a few questions. Basically, I changed a few config settings on my ubuntu 10.10 load. I made it so I can connect to it remotely via ssh and open a secure desktop session. I changed some port settings so it doesn't use the traditional ssh 22 port and traditional xrdp port was change also. So, I'm wondering if my "tweaks" will remain intact after the update or if I'll have to go back in and reconfigure those settings? I'm running 10.10 on my PIII 600 with an old ATI Radeon 64 graphics card. I'm quite happy with 10.10 but if I can upgrade to "natty" will little problems I'd like to. Also, my default GUI is xfce. Also, here's my system as shown by lspci:
I've just upgraded my Ubuntu version a week ago and got a problem that the Unity UI won't running after upgrade. My laptop is Dell Inspiron 14R which is i think is more than capable for running Unity 3D. When I rebooted after upgrade there was just a blank wallpaper screen, without Unity interface at all.
When I first boot up. I get the GRUB command line. What happened to the boot menu? And I can boot up into my Windows partition just fine. But when I try the other partitions i get "Unknown file system" or when I try to boot into the other ntfs drive, I get "BOOTMBR missing", but yet it does not mean Windows, because i can boot that just fine. I can't find my Ubuntu partition. How can I get the GRUB boot menu back?
