Ubuntu Installation :: Regular Update Now Can't Boot From HD Or CD?
Oct 7, 2010
I updated my Ubuntu 10.04 on Dell 1330 and on the next boot it failed. I get a series of messages, the main point seems to be that it can't find the files it needs to mount.I tried booting from the live cd I used to install 10.04, but it can't boot either due to wrong user id error and maybe trying to boot from wrong kernel?At this point I am willing to just wipe the hard drive and do a fresh install but how to do that if I can't run the install cd?Or is there a way from initramfs to solve this?I tried mount /dev/sda1/mnt but it says cannot read /etc/fstab no such file.libdevmapper

I did an update during a time when power was cycling due do a nasty snow storm, but I'm pretty sure the update was completed successfully before I lost power. What did happen though is that my BIOS setup was reset.
Now if my HP Laserjet 1020 is plugged into USB during boot all other USB devices freeze for a while. So I played with my BIOS setting for USB:
- Enabled V1.1 and V2.0
- Disabled System USB Shadowing
So now my bootup doesn't hang. But now when I actually go into Karmic I still can't print.
dmesg shows the following:
[ 205.940008] usb 1-10: new high speed USB device using ehci_hcd and address 9
[ 219.510026] hub 1-0:1.0: unable to enumerate USB device on port 10
[ 223.430008] usb 1-10: new high speed USB device using ehci_hcd and address 10
[ 223.600766] usb 1-10: configuration #1 chosen from 1 choice

Got it on a CD and was using it as "Try Ubuntu" instead of installing it for good (I still wanted to see if there were memory issues or HDD issues with my desktop, before I installed it for good).Anyway, I would shut down the pc after about 2 or 3 days and redo the CD install (try ubuntu option) again and add all the plugins etc.Kids used this for playing some games on friv or nickjr.The real issue - of late, when I try to start the PC and boot from the CD, I am getting a LOGIN screen instead of the regular option to install from CD or Try the Ubuntu.

I have Mythbuntu 10.04 installed on an exclusive HTPC and working great... until tonight. After letting the system update some packages (161 packages if I remember right), I suddenly have an issue where the graphical system won't start. After researching I found three error messages that might be causing that.
1. At the start of splash screen I see "UUID=xxxxxxxCD7 not ready yet or not present" I checked in /etc/fstab and found that this is the swap partition. I don't remember seeing this before so this could be the culprit.
2. I'm not at the computer in question right now but I saw a Plymouth error about "mountall" and then the message "plymouth command failed". Not sure if this could be the main error.
3. after a while (usually ca. 1-2 min) I receive thousands of errors of the kind "out of memory"... "kill process XXXX" (process vary wildly e.g. dbus-daemon, mysql, etc)... "process killed"..."respawning"
After error 3, I'm not able to switch to graphical console (ctrl-alt-F7). If I was in the graphical console at this moment, I simply can't switch to the CLI console. I'm always afraid of updating my system since I've seen lots of things breaking afterwards (usually the proprietary graphic drivers) but this is really strange.

I was looking through the Debian FTP site, and noticed
debian-504-amd64-DVD-1.iso
and with a modification time only about 24 hours later,
debian-update-5.0.4-amd64-DVD-1.iso
Whats the difference between these two?

After doing a regular software update on a 5.5 box (and rebooting), I now have problems starting xen (version "xen-3.0.3-105.el5_5.3.x86_64").
Running "/etc/init.d/xend start" yields no output, and checking the script, I see that the script halts if "/proc/xen" doesn't exist.
Checking the filesystem, I find that the "/proc/xen" entry is indeed gone. Restarting the CentOS box does not help.
Should I reinstall Xen? If so, should I remove any portions of Xen before I do?
Update:
When I run /usr/sbin/xend I get:

My self-built PC had a BT wireless adaptor in it which worked, albeit after a bit of a faff, with Ubuntu 10.10 in connecting to my BT HomeHub2.
When I came to use it last week it would not connect. I'd not changed any hardware but I had been applying regular updates via Update Manager.
Bearing in mind the "faff" factor, I decided to try a different (Edimax) wireless card but got the same result. Upgrading to 11.04 has made no difference either.
It does *try* to connect but fails, so I think the card is installed correctly. I've also tried a full reset on the HomeHub and the setup works fine with W7.

I'm running Fedora 11, and just did an update of the system. It looks like there was an update to the package that takes care of knetwork manager. In the past, I have played around with it, but it hasn't met my needs, so I went back to nm-applet, which works fine.
I'm curious about the update, and would like to see if it works. However, knetwork manager won't start as there is another network manager already running (there is a message about this everytime I log in). I can easily kill nm-applet, but logging out and back in causes it to reload, and I still get the message from knetwork manager. So here are my questions:
1) With the update, is knetwork manager stable and robust enough for regular use (the docs for F11 said it wasn't upon F11 release, so included gnome's network manager as the default network manager)?
2) How do I get knetwork manager to work (I presume this means I turn off Gnome's network management and switch to knetwork management)?

I have GRUB on my laptop with Ubuntu and Windows 7. GRUB and Windows 7 seem to boot just fine, but recently, Ubuntu doesn't boot. My suspected cause is simply because I've often shut down unofficially. My laptop doesn't have a battery, and even the AC connection is awry, so as soon as an accidental disconnection or something occurs (because it too is broken), it'll essentially shut down.
I try booting Ubuntu, and it doesn't boot. I think I see that Ubuntu and the dots page, but it'll hang there (and I waited overnight). Immediately, I want to run an fsck, but I seem to be unable to, so I run Recovery Mode. I always get a forever loop of a bunch of stuff that doesn't make sense to me, but this is one thing that I always see (or something similar).

When I boot my pc it used to take me to a prompt which asked which OS I would like to boot. Today randomly, some grub rescue menu came up. I read online that that meant I had to fix my grub menu, which I did. Now a regular grub menu pops and and I have no idea what to do with it. Whats a grub menu? How can I just get back to my regular boot screen? I run dual boot xp and ubuntu, is grub a program of xp or ubuntu? I have no idea what this grub menu is and whats going on with my pc!

A few weeks ago I did a WUBI 10.04 LTS install on a Windows XP desktop that went perfect. System ran great until this morning. I was prompted to install "Security Updates", which I allowed the system to do, but thereafter was unable to boot. What happens is at the point of selecting either Windows or Ubuntu for booting, and I choose Ubuntu, the computer goes right back into a re-boot process and brings me back to the Windows/Ubuntu boot selection prompt. It doesn't even bring me into the secondary boot level of asking which type of Ubuntu boot I want (generic, etc.). Is there a solution for this problem besides reinstalling Ubuntu?

A few days ago I updated my openSUSE installation on my Acer Aspire 5920G notebook from 11.1 to 11.2, but I haven't been able to get any kind of graphical shell loaded. Using the regular "desktop" option in GRUB results in a black screen. seems my PC is still responsive though as hitting Ctrl+Alt+Del like a mad man results in the PC getting rebooted after a while. I had the same "black screen" issue with the KDElive CD and the regular installation CD (Yeah, I should have known better than to do the upgrade...).
When opting for "Failsafe" in GRUB, I reach a command line. Before that it seems to try to load GNOME (you get to see the cursor) but fails at it a few times in a row. When I try to start GDM afterwards from the command line, it gets into a loop in which it tries to load, then crashes and then tries to load again, endlessly.I have installed the newest NVIDIA drivers "the hard way", and my card (NVIDIA 8600M GT) is on the list of supported devices on the NVIDIA website. SaX2 seems to work OK with it.

Is there a way to get the matching Linux kernel headers automatic on a regular kernel update via the Ubuntu packed manager? Every time I get a new kernel I must do an aptitude install linux-headers-`uname -r`

I forgot the root passwd for linux (via the "single" mode) and, according to all confirms, did so successfully! I then try to log on to Centos as root, and I can't....it says "incorrect passwd"! So then I log on as another, regular, but not root, user, with that passwd, and boot up into Centos. if I try to "su" to root, with the new root passwd, again it says its incorrect. there is no "system admin" passwd set. I checked!. I need root access within Centos!

I updated from 10.04 to 10.10 this afternoon, and after a reboot, I can't start ubuntu in the new kernel. Grub shows up fine, but after selecting the new kernel, all disk activity stops after a while. When booting in safe mode, the same thing happens.
Oddly, booting in the old kernel does work. I'm not sure which log files might be of use here, so haven't gotten much further..
[edit] Just tried to boot in the livecd, doesn't work either, same problem.... I guess there is a driver problem somewhere most likely

jump straight in with a problem. I'm experiencing the same problem mentioned here; where it was suggested to start an individual thread.I have been using ubuntu as a dual boot with vista for a couple of months. Apart from a few hiccups I've been very pleased, but after an update I am unable to boot ubuntu. It appears to be the same issue in the link above.
I originally installed 10.4 (because my first attempt with 10.10 would not install (turned out to be duff CD)) and then updated to 10.10. All was fine until this latest automatic update.I've tried a few things suggested -- copying the c:ubuntuwinbootwubildr file over c:wubildr -- with no luck... I'm worried about making things worse and thought I'd ask first. I hope that's OK.I also tried working from my liveCD, but it only gave me the option to install (because it's 10.4 and I've updated?

I updated to 11.04, looked down after about an hour and a half, and my laptop was off. Now when I turn it on, it acts like it's checking my desk, but it says something like "/ is not available or doesn't exist press s to skip, or m to manually recover" then when you skip it's like "/mnt is not available" It could be possible I accidentally turned it off during the upgrade.

I recently installed Ubuntu 11.04 via wubi.exe to dual-boot between Ubuntu and Windows XP Home Edition. Ubuntu was the default OS to load on boot. I tried running a few updates in Ubuntu through the update manager, followed the instructions in the wizard, and restarted my computer when asked. The computer now automatically boots straight into the "GNU GRUB version 1.99~rc1-13ubuntu3 Minimum BASH-like line editing is supported..."
I have only just started to get into Linux. I have no idea how to get through this portion. I can't load back into Windows either (at least...I'm not sure how to. I never get the opportunity to choose which OS to launch). I've tried researching this issue, but still not having a lot of success. My only current option is to completely reformat my HD, but this is (hopefully) not going to be needed. If I could just get back into Windows I think I could probably reinstall with Wubi.

Yesterday I got installed Ubuntu 11.04. After I got updated with update manager everything was OK until I rebooted the system so that update can tack effect. When I rebooted It's stuck in the middle of something. (No GUI). I tried recovery mode but same thing. Then I tried Previous version and it worked fine. Now I can boot into system but each time I need to select previous version.

I just allowed Update Manager to install the latest security updates to the Linux kernel, header and xorg and clicked on restart system. After selecting Ubuntu from the system's boot manager I'm dropped into a Grub command line and don't have any idea what to do next. I'm running Ubuntu 9.10 inside Windows 7 on a Toshiba L500 laptop using the Wubi setup.

So i have a second PC, which has 2 HDD's in it. Windows 7 is installed on the first HDD, (640GB) and i have Ubuntu 10.04 installed on the second HDD (80GB). This was done basically by "OldFred" 's directions.[URL]...(First few posts on thread i linked will inform how i have my Dual boot setup) So far i haven't really used Ubuntu much. And from reading on here, 10.10 isnt to stable, but still im interested in knowing:
Is it safe (considering my dual boot setup) to update my Ubuntu version? I am assuming when in my 10.04 it would tell me a new version is out, but maybe it doesnt upgrade like that, you tell me please. Basically i am concerned for messing up my dual boot setup considering if something goes wrong , i dont want to mess up my Windows 7 OS or the time taken to successfully install the dual boot.

I made a usb install drive on a mac by following the instructions on the ubuntu download page, but had problems getting the GRUB loader to run the USB at boot on the DreamLinux PC i wanted to install it on, so I have now sorted access to a CD writer to make a liveCD.
However I need to convert the USB FDD back to just a regular FDD for my mother to use. I am not at all familiar with Macs, or the terminal utilities (though I am able to use the terminal to some degree) so would appreciate help with this procedure or a pointer to some steps to do it.
Currently the drive is named Ubuntu 10.04 LTS when it mounts on mac, before the img write it was just untitled, I cannot delete the ubuntu files from it or write new ones, and I don't know how to do a reformat on a mac.
I need he drive to be able to work again with windows and mac... so will need to reformat to FAT32 I guess?

same thing happened when version 17 came up. I definitely NEVER again going to update kernel. What do I need to do now? should I uninstall latest kernel...if that is possible?
