Ubuntu Installation :: Md5sum Mismatch- 10.04.2 Alternate Install?
May 16, 2011
I downloaded the Xubuntu 10.04.2 Alternate Install CD ISO file from http://mirror.anl.gov/pub/ubuntu-iso...10.04/release/
When I checked the md5sum of the downloaded file, however, there was a mismatch.
The md5sum given at both http://mirror.anl.gov/pub/ubuntu-iso...elease/MD5SUMS as well as https:[url].... is 209cfc88be17ededb373b601e8defdee *xubuntu-10.04.2-alternate-i386.iso but running the command,
Code:
md5sum xubuntu-10.04.2-alternate-i386.iso generated the following, obviously different checksum for me:
098674ad5a59f0115030c5c0c3973899 xubuntu-10.04.2-alternate-i386.iso
(It also took unusually long to generate the checksum- around thirty minutes.)
Is it possible that the file was corrupted or tampered with on the server?

Used to run Gentoo, years ago, getting back on the linux train. Anyways, got a new media pc and am having some troubles getting it to function. I am using ImageWriter, an OCZ Rally 4gb flash drive and have tried both HTTP and BitTorrent downloaded copies of 11.3 with the same md5sum check wrong error. What am I doing wrong? Is it because it thinks it is a CD or am I getting bad copies of the ISO? I am so out of practice I can't remember anything about installation anymore and am at a loss.

I've tried the Universal USB Installer, but that doesn't support the alternate iso. And if I select the regular desktop one, it screws up the installation when I try to boot.
Unetbootin gives me this error during the cdrom process. It says it can't find copy files from cdrom and stuff. Well of course, there's no cdrom...

i have a Compaq Presario S4020WM
2.0Ghz XP2400 CPU
768Mb RAM
2 40Gb Hdd
and a HD raedon 4650 AGB 1Gb Grafics Card
I have tried to install Ubuntu with this CD and it gets past the keyboard detection part and then it tells me i need to get the CD ROM drivers via removable media, i know this is a problem with ubuntu 10.04 because i can install just fine a 8.04 ubuntu.
i don't know what to do.I have tried to install from a USB but my comp is too old for that, i know its not the specific cd because i'v used about 5 different brands of cd just to see if it was the cds i was uesing,
I would just upgrade from 8.04 to 10.04 but i get to the dbus part and the comp starts to run really slowly and eventually colors just show up, i left it for an hour to see if they would go away and fix but they didn't. Iknow my comp CAN run 10.04 because i have done it before, but i uninstalled and now i can't seem to get it to work again.
P.S. i have tried the live cd, same effect.

Today I decided to replace my 9.04 install with 10.04. (I did this on a separate hard disk.) As I am a big fan of LVM I used the 'Alternate' install CD. Everything installed fine.
However, upon booting I observed two things: firstly there was no grub menu. No countdown timer, no menu. Just a flickering cursor. After 15 seconds or so I got a message telling me that:
Code:
/dev/mapper/bromine-root (My root partition.) does not exist and that it had given up waiting. Finding this kind of strange I tried the alpha of 10.10 --- same again. Hence I have two questions: firstly, where did the nice grub menu go; secondly, what is wrong with LVM and grub these days? At the initframfs prompt I am thrown to there are some LVM utilities and they appear to show my volumes.
Switching back to my old pair of hard disks and everything works as expected (i.e, the hardware is fine and supported by Linux.)

UPDATE: decided to reinstall and run the partitioner to get rid of the raid. Not worth dealing with this since seems to be lower level as /dev/mapper was not listing any devices. Error 15 at grub points to legacy grub. So avoiding the problem by getting rid of raid for now. So ignore this post. Found a nice grub2 explanation on the wiki but didn't help this situation since probably isn't a grub problem. Probably is a installer failure to map devices properly when it only used what was already available and didn't create them during the install. I don't know, just guessing. Had OpenSuSE 10.3 64bit installed with software raid mirrored swap, boot, root. Used the alternate 64bit Ubuntu iso for installation. Since partitioning was already correctly setup and the raid devices /dev/md0,1,2 were recognized by the installer, I chose to format the partitions with ext3 and accept the configuration:
/dev/md0 = swap = /dev/sda1, /dev/sdb1 = 2Gb
/dev/md1 = boot = /dev/sda2, /dev/sdb2 = 256Mb
/dev/md2 = root = /dev/sda3, /dev/sda3 = 20Gb
Installation process failed at the point of installing grub. It had attempted to install the bootloader on /dev/sda2 and /dev/sdb2. I moved on since it would not let me fiddle with the settings and I got the machine rebooted with the rescue option on the iso used for installing. Now, I can see the root partition is populated with files as expected. dpkg will list that linux-image-generic, headers, and linux-generic are installed with other supporting kernel packages. grub-pc is installed as well. However, the /boot partition or /dev/md1 was empty initially after the reboot. What is the procedure to get grub to install the bootloader on /dev/sda2 and /dev/sdb2, which represent /dev/md1 or /boot?
Running apt-get update and apt-get upgrade installed a newer kernel and this populated the /boot partition. Running update-grub results in a "/usr/sbin/grub-probe: error: no mapping exists for 'md2'". grub-install /dev/md2 or grub-install /dev/sda2 gives the same error as well. Both commands indicate that "Autodetection of a filesystem module failed, Please specify the module with the option '--modules' explicitly". What is the right modules that need to be loaded for a raid partition in initrd? Should I be telling grub to use the a raid module?

I have a Gigabyte 6A-M61P-S3 with an nVidia chipset, and I'm using the built-in graphics rather than a discrete graphics card. Ubuntu 10.10 and previous releases ran flawlessly on it using the nouveau drivers. I tried doing an upgrade to 11.04 using the Alternate AMD-64 CD, and it seemed to complete successfully, but when it came time to reboot, I had no video output at all after the BIOS screen. This is a test machine, so I went ahead and did a clean install using encrypted LVM with the Alternate AMD-64 CD after confirming that 64-bit 11.04 ran fine using the Live CD.
The installation went fine, but the first reboot flashed a brief "error: no video mode activated" and then I lost all video output. Subsequent reboots didn't give me any error message, but I had no video output. I suspect there are some boot parameters that would have gotten the nouveau driver working, but I wanted to try Unity, so I rebooted to get the Grub menu, chose Recover Mode, selected failsafe graphics, and got to the Desktop, then installed the proprietary nVidia driver (current) and once I rebooted everything was golden.

is there any way to do a 11.04 Alternate Command Line Install without Internet Connection? I try to install Ubuntu on a Internet-Tablet, wich has no Ethernet-Port and I don't know how to get Wifi to work during Alternate-Install. At previous Ubuntu versions it was possible to let network be unconfigured and install completely from CD or USB-Stick. Isn't this possible in current versions?

Where can I find the md5sum checksum for Ubuntu 10.10? They seem to keep it hidden.

I checked the md5sum of the iso using winMd5Sum utility, it is OK.
To check the CD, right clicked the md5sum file in it, send to winmd5sum, and then copied the corresponding hash from the ubuntuhashes page into the bottom text box, and compared. The message box says md5 sums are different. Now the question is, have I done it correctly, I mean, is this the way to check a burned CD, OR, is there another way to check md5sum of a burned CD?

In order to upgrade a machine that can not successfully upgrade to 10.4 I downloaded and burned the 10.04.1 iso image off the ubuntu alternate download site. In my first attempt I unsuccessfully burned the image with it failing at the very end. I did perform an md5sum on it and received the precise output I got from my second burn attenpt which DID complete successfully. Here is the output:
[code]...
I did research this last night and it seems the common wisdom was to reburn the iso (which I did twice) or copy down the iso again. This I also did and it came down precisely, bit for bit, the same as the first one. Here are the two cksums
[code]...
Is there something wrong with this image on the website or is the error about 1 file being unreadable (could that also mean missing?) be erroneous?

Long story short - I'm looking to run a live CD so I can alter my existing 10.10 x64 installation. The standard desktop install CD results in a graphically corrupted window (a grainy grey field). The alternate install CD does get me to its text menu, but the shell I open operates on the ramdisk the install CD creates, not the existing hard drives. I can't seem to get the alternate install CD to do anything to my existing file system.
I'm using the x64 alternate install CD off a USB key. Short story long - I'm trying to convert from ext3 which I've inherited from upgrading all the way from Warty, to ext4. I see instructions on how to do it and the best way is using a live CD, so I need to see the existing file system from the live CD via a shell.
As my 10.10 install is working just fine, I'm getting less and less inclined to mess with it at this point, so I may just abandon it. But I understand ext4 is much faster than ext3, plus I always learn a lot when I go through things like this, so this is just a question before I give up.

I was thinking of creating an extremely minimal version of Xubuntu using XFCE. I have a Dell Mini 9, a netbook that uses a wireless-g card requiring bcmwl-kernel-source to work.What I would like to do is use either the alternate CD or mini.iso minimal install file to perform a command line install-style installation of the system.So far, what I am thinking (from reading this [url].... article:
HTML Code:
http:[url].....is to start off with these packages to begin with:
xorg
slim (if possible with 9.10, unsure if it is still available. in short, i want to use a lightweight display manager)
xfce4
xfce4-goodies
xubuntu-default-settings
bcmwl-kernel-source
aptitude
My opening questions are: Should I go with mini.iso or the Xubuntu Alternate Install CD (or the Ubuntu one)? If so, which one? What additional packages will I need to make the hardware accessible and fully functional? All I can think of so far would be sound (I'd like to stay away from PulseAudio if possible, it wreaks havoc with my computer), my webcam, and the memory card slot, if additional packages are needed for it?What other "core" packages should I include in this list? Should I include Synaptic, or other packages, and why?What do I need to take into consideration, since this is both a directly- and battery-powered computer?

sudo apt-get install ubuntu-desktop fails and has been failing for the last two days, I installed both the lto and the 10.10 newest, starts out OK and runs for about 5 minutes then finishes with many 'failed to fetch [URL] size mismatch issues. This is the first one after many installs over the last two years. Is there something going on with the US servers? On closer examination of running sudo apt-get update it seems to be fine till it hits the pool directory on the server, lucid main and lucid-updates are fine, breaks when it goes past those.

I have Ubuntu 10.10 installed and a few weeks ago I tried upgrading to 11.04 using "Update Manager" BUT I got the following error after a few hours of fetching all the files from internet except for one
Code:Could not download the upgrades
The upgrade has aborted. Please check your Internet connection or installation media and try again. All files downloaded so far are kept.
Failed to fetch [URL]
I thought there's something wrong with the internet connection in spite of that everything else works well.. I tried upgrading in different times in different days, I redid the process again today and I got the same error again. Is there any other way to upgrade or ignore this package?

I'm currently installing GTK+ under Fedora Core 13. Before you install GTK+ you have to install GLIB, Pango and ATK. When installing ATK it goes wrong. After giving the "./configure" I get following error:
checking for GLIB - version >= 2.0.0...
*** 'pkg-config --modversion glib-2.0' returned 2.25.8, but GLIB (2.24.1)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system
[Code]...
Apparently there is an old version of GLIB on my system bugging my installation process. Does anybody know how to get rid of this old version?

I am trying to do a 'light' install of Ubuntu 10.04 using the alternate install CD. Here is how i am planning to do it:
1. Perform a console only installation(Standard system only on d-i tasksel)
2. Install gnome-core
3. Then install the packages i need using apt.
1. Would such an installation lead have any significant performance(RAM usage) advantage over a full fledged installation?
2. Is there a way i could install gnome-core from the installation CD instead of downloading them from the repository?
3. Would installing just gnome-core mean that synaptic & update-manager wouldn't be available? i am hoping that it wouldn't be the case I checked their dependencies from packages.ubuntu.com, it doesn't look like they need gnome-desktop-environment to be installed first.
4. Would such an install have any more device driver related issues (eg.display drivers) than a regular install?

I've upgraded to the new 10.04, and when I have the Alternate CD in, it shows on my desktop, and I can search all the contents of the CD, so I know it's registering. But when I try to install anything, via the terminal, .deb packages, synaptics package manager, it always asks me to insert the CD. Then I click ok and it says it's not mountable, even though I know it is because it's on my desktop.

Is the Ubuntu LTSP install still on the alternate CD as of Karmic? Or has it been moved (say, to the server CD)? Websites say it's on the alternate, but there's no way of knowing if they're up-to-date.
