Ubuntu :: Upgrade For 11.04 - System Can't Be Recovered
May 14, 2011
I recently installed Ubuntu 11.04 from clean and installed Gnome 3 without any errors. If you don't want to read all the chit-chat, you can just read the "Resume" paragraph. I received an Upgrade, but could only partly upgrade. I thought "Yay, updates! It can't hurt, can it?". While I upgraded, a friend of mine contacted me to tell me not upgrade, because it broke his Ubuntu. Too late, pal. When it was done upgrading, I could just sit there looking at dialog box saying: "Click restart to buy your tombstone". I finished my work and restarted to find that there was no problems what so ever. I booted up and logged in to find this message covering the entire screen: It is in Danish, so let me translate it for you:
[code]...
I then discovered something strange. I could press the Super-key and see the Gnome 3 interface. I could run programs, but as soon as I chose a desktop, the message from above would lay on top of the entire screen once again. I managed to save some screenshots by holding Enter, while clicking on the "Save screenshot" window......

I had lost my emails and contact after using Evolution. some of forum user recommended to use photorec to recover all the files. I used and have stored all the files in a folder. Now my problem is there are over 1500 folders and in there over thousand and thousand of text files. How should I recognize which folder contains email and contacts and how to import to Evolution ?

I have recovered most of my USB drive, but a couple of folders are locked and look like files. I'm unable to change permissions on them and "You are not the owner so you cannot change these permissions." appears in the properties tab. The owner is "184444735 - user #-184444735" and the group is "17414907" which makes no sense to me. Most other folders and files are OK. The disaster I recovered from was a partition move that failed. I used fsck to get most things back. Any idea how I get these couple of folders (the most important one is one of them "Documents" of course). to be visible?

I have an 8x1TB raid6 array that I finally got back to a good state (see my other post here: [URL]..This is on a 9.04 server Now I can assemble the array no problem, but mounting is the issue. I think the reason might be because the array order changed. In the process of recovering I removed the /dev/md0 array and created a new array. In the create array command it told me:
Code:
mdadm: /dev/sdb1 appears to be part of a raid array: for each device in the array. I confirmed that I wanted to continue and the array was recreated. I think this overwrote the superblock, but I'm not sure.
After the sync I tried to mount the array using:

I managed to very stupidly (and avoidably) overwrite the hard drive that contained all my stuff--music, photos, home videos from the 80's that were painstakingly converted to digital movies, etc.After running Photorec and recovering much of the data to another disk, I'd like to be able to rename the music files using whatever exif data/tags are available.

I decided to give Ubuntu another try and installed the Studio version. During my installation it asked whether I wanted the Realtime kernel or not. I chose yes as I figured it could come in handy when I work with audio.However since this version isn't exactly Ubuntu 10.10 as promoted , I decided to install Ubuntu Desktop on top of it (trough apt-get). For the full experience. ( im not even sure if it just installed extra software and added some folders)Now my questions are:1:The Realtime kernel is it now overwritten by any other kernel that came with the Desktop installation?
2: How will the updates handle my installation once i want to upgrade to, lets say, 11.04.I'm not really sure about how the system will look at things to upgrade. Will it look at my Desktop installation or my Ubuntu Studio? ( concerning the Realtime kernel as well).Just to add some more: I'm a total Linux Noob(although im not scared to use the Terminal)

I decided to swap my existing small hard drive for a bigger one which went well. Then I formatted the old drive using a windows vista machine before putting it on my spares shelf. To my amazement after formatting my 20GB hard drive had become an 8GB hard drive. I fear the worst but remember that Ubuntu put a large swap file on the drive and wonder if Vista has just ignored the system partition. I tried attaching it to my Ubuntu laptop which reports a healthy 8GB hard drive even after formatting again. I don't know enough about Ubuntu to try repartitioning it in that so I tried DSKCHK in windows which reported a healthy 8 GB hard drive. Is all hope lost or is it a "hidden" partition which might be recovered under Ubuntu? If so, how?

I have upgraded my system from 9.10 to 10.04. I get the following error when I start my computer.
A error occurred while Mounting 0
Press S to skip or M to manual mount
This is my fstab below, what do I need to do to correct this startup problem.
# /etc/fstab: static file system information.
# Use 'blkid -o value -s UUID' to print the universally unique identifier for a device; this may be used with UUID= as a more robust way to name devices that works even if disks are added and removed. See fstab(5).....

I'm putting this in general, because I'm not sure if many of the specifics are relevant.I have an everex cloudbook which I purchased from eBay with hardy herron on it.I finally got around, today (I've had it for a year), to installing netbook remix 9.10 with a usb key I had also purchased from eBay.Now, during the upgrade (using update manager) from 9.10 to 10.04, the system appears to have frozen.(desktop frozen, no response to keyboard or mouse).Now, I'm not sure if something could still be happening inside there, and if it would be a good idea to let the machine site overnight before rebooting it. Frankly, it happened once already, and I rebooted, and update manager just took up where it left off once I logged in.
I have not determined what's causing these freezes. It's not a new machine, of course (everex, afaik, doesn't even exist now), so maybe netbook-remix is too taxing on the hardware? I installed xfce to get away from the bloated netbook-remix graphical menu garbage, which did seem to allow the system to run faster. Anyway, the real question here is, while the interface appears frozen, could the upgrade still be developing under the surface? (I hear a fan running in there. There is no hdd to spin, but flash memory, so I don't know if the fan is any indication of internal activity). Would you wait to reboot it? (update mgr indicated 4 hrs remaining to upgrade, in the installing upgrades phase, not downloading, appears it froze during "Running post-installation trigger install-info"). Or just reboot it and see what happens (get update mgr to start again?)? The system never froze on me with hardy. It was pretty quick and snappy, in fact.

I just finished upgrading from 10.10 to 11.04 and restarted my system. It had been working fine, but now, after the POST test, the screen goes black, then a box floats around the monitor saying "Input Not Support." Pressing CTRL+ALT+DEL reboots the system to the POST screen, then the same thing happens. No hard drive activity, no boot, nothing. I really don't want to lose everything on my hard drive with a fresh install.
My system, a Compaq Presario, has diagnostics, so I ran that at startup, and it says I have no active partitions.

I run three Ubuntu machines - work, home, and a laptop. All were on 9.04, and I was able over the past week to painlessly upgrade the first two to 9.10.Today I fired up the laptop for the first time in a while and saw that it hadn't had the upgrade yet, so went to the upgrade manager. It had a bunch of package upgrades it wanted to do, so I let it. But there was no option to go to 9.10, not even after catching it up on updates. It just says the system is up to date. Clicking "check" again just gives the same message. It doesn't seem to know that there's a koala out there.
Settings on the update manager say to accept normal releases, so it's not an LTS thing. Yes, it's on 9.04 now according to /etc/apt/sources.list. Network connectivity is good.What might I be missing that I ought to look for?

I upgraded several months ago from 8.04 to 9.10 and found my system slowed considerably.I thought I'd get used to it, but it just seems to really drag. I'd like some suggestions on how to downgrade or alternatively speed up the system (are there items I can "turn off" that can bring back the speediness of 8.04?).I'm considering wiping and re-installing, but getting my system back the way I want it is keeping me from doing that.

After successfully upgrading from 8.04 to 8.1 (where even my wireless worked for the first time) I got a system freeze when I tried to upgrade to 9.04.
I suspect the graphics driver but don't know how to upgrade without X running. After booting in generic mode (kernel 2.6.28-1 I can log in the shell but am lost without the GUI.

I was trying to upgrade to 10.04 (from 9.10 x86_64)when the update manager crashed without any warning or errors. it happened while the packages were being installed, as a result of which i could no longer login into gnome. so i logged in using the terminal and since i had cleaned the cache before upgrading i ran sudo -i dpkg *.deb (there were a large number of deb files in it, so i thought those were the upgrade packages) but the process couldn't be completed. it said that there were too many errors. after rebooting, gnome doesn't start and i can see lucid development version in the terminal. it also didn't detect my usb keyboard.do i have to reinstall ubuntu.

Is it possible to upgrade an Ubuntu install which is using software RAID?
I ask because I'm currently using Fedora, and one of my huge frustrations with the distro is that if you're using software RAID, the installer explicitly notes you can't upgrade to future versions. Instead, it requires that you wipe your entire drive and do a full reinstall to acquire the next release. I presume Ubuntu probably uses many of the same libraries to support software RAID as Fedora, so does Ubuntu also have this limitation?

I'm currently experiencing a problem when trying to upgrade my system through aptitude (apt-get *). I can install programs, but whenever it tries do anything with the kernel I get this error:
E: linux-image-2.6.32-24-generic: subprocess installed post-installation script returned error exit status 2
This started about a month ago when I was trying to install some upgrade (with apt) which stalled and I unknowingly shut down the comp while it was running.

I talked a friend into trying Ubuntu, and installed it via wubi. So far, he likes it a lot, but today I checked his computer out, and saw that he had a lot of updates pending. There was a kernel update, openoffice, grub, the whole lot. So, I started the update, and, when it finished, the system froze.
I restarted the PC, but now Ubuntu says that the root partition is not ready. When I open a diagnostic shell, it says "Root filesystem check failed". However, an fsck works just fine, and I can see all the files in both Ubuntu and Windows.
There's only one real disk, as far as I can see, /dev/sda1, and it's the Windows disk. The Linux root is a /dev/loop5 which points to a file under Windows. I suppose it's the wubi way, although I'm not familiar with that.
There's a possibility that the Windows disk had errors while I was running Ubuntu; in fact, Ubuntu said something to the effect while booting the first time it failed.
What can I do to boot normally?

I have dual boot (wubi) Windows XP. It was working smooth until I upgrade ubuntu 9.10. At the boot screen I choose Ubuntu, then it ask me wich version, then it freeze. I tried the recovery version, but then it ask me for a user ID login and password. At this point I'm able to enter the user , but it don't type anything on the password and keep asking me to enter the user id and password again, and again.

I have the System of 9.04, but have a Live CD of Ubuntu 9.10 too. But, I do not want to download all the massive Upgrades. Still, Ubuntu 9.10 is the best! So, can I upgrade 9.04 to 9.10 using the Live CD? (Offline).

I have an AMD64 system, which I recently upgraded to Lucid 10.04. The system now fails to boot after the upgrade. Recovery mode makes no difference.
When I attempt to boot, I get a series of messages about file systems needing checking, and also some messages from ureadahead-other. (process terminated status 4), though a post here says that status 4 is in fact not an error.
I have sucessfully booted the Lucid desktop install CD in live CD mode, mounted the filesystems, and started parts of my system in a chroot. In that system I tried running an update, and removing plymouth, but it made no difference. how I can get my system working.
I did take a backup of /etc before I upgraded, so I could get back to a karmic install, but the pain in doing so would be considerable, so I would prefer to avoid that if possible.

I've just reported a launchpad bug report about my desktop system being unbootable after upgrade to lucid lynx. [URL]... I opened this thread to ask if someone else experienced a similar problem and for collecting information and workarounds (none yet) about this quite serius problem. The system has an nvidia graphic card and proprietary drivers were installed before the upgrade. However I'm not sure the problem is related to this. FYI, the system booted regularly from a usb stick with ubuntu lucid lynx. SO the problem is in the upgrade path.

I tried running an upgrade from 8.04 LTS to 10.4 last night, and things seemed to be going smoothly. The upgrade progress was nearly complete, and I wandered off for a while to let it run. When I came back, I had nothing but an orange screen and and unresponsive system. I left it alone all night with the hopes that something would happen, but this morning nothing had changed so I hard restarted the system.
Ubuntu 10.4 appears in GRUB, but the system cannot boot and exits with a kernel panic and the message "vfs unable to mount root fs on unknown-block" I was able to boot to a 10.4 LiveCD, and I can browse all of my files from there. What can I do to get this system back up an running? I have dozens of user account and a lot of customization (it acts as a webserver with a wiki for a gaming website running on it, among other things), so I really really don't want to do a fresh install and lose all my data and customizations.

A server of mine previously running ubuntu 9.10 used to be between 0.01 and 0.10 load average during the normal load of users using various server programs on it (mostly apache with php scripts).
Now, after upgrading to 10.04 (which went smoothly for the most part), the load average is much greater under the same user workload, hovering between 0.1 and 0.3 under very light work and up to and over 1 regularly when more users are accessing the same scripts.
Are there any known issues that would cause greater usage of the same resources in lucid, or are there any ways I can trace what's causing the higher load? Downgrading or starting with a fresh install are last resorts, as there are a lot of customized options specifically set up for this server and I'd rather not go through backing them all up and restoring them after a complete wipe.
