I am trying to put Ubuntu on my USB.
I use the tool here (as recomended by Ubuntu) to put it on my USB. It seems to work well up until it says "Data error in 'casper/filesystem.squashfs'. File is broken".
I tried to install it anyways (I know how to work the BIOS and everything) and the installation just stops with an error message.
I have had a dual boot on my system since first trying Ubuntu a few months ago.I had a few problems when i upgraded to 11.04 (mainly due to the new desktop Unity), but after some great help here, we had the old desktop running again.I have Windows running on my spare Computer in case i should need it for any reason, though can not think of one lol Now i am used to Ubuntu (from the using side, get lost in terminal etc so here i come if i need help) i decided i would totally commit my main computer to Ubuntu.I downloaded the latest iso from the Ubuntu site, and burnt it to CD, inserted in my main computer & rebooted. It goes past the first purple ubuntu page (hit a key to choose language & also get a selection Menu) then goes to black screen and i get:
BusyBox v1.17.1 (ubuntu 1:1.17.1-10ubuntu1) built-in shell (ash)Enter 'help' for a list of built-in commands.(initramfs) mount: mounting /dev/loop0 on //silesystem.squashfs failed: Input/output errorCan not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs(hope i typed that i correctly)I have burnt the iso image numerous times, using different disks, speed (from x4 - x52) and burning programs
Trying to install 10.04.1 Kubuntu desktop to Toshiba T110 laptop running Win 7, 4 Gig Ram, 32 bit o/s. Downloaded iso from Ubuntu web site and burnt DVD. No matter what I do I get the error message "cannot mount /dev/lop0 (/cdrom/casper/filesystem. squashfs" etc. Searched by Google and this forum, tried various remedies Unebootin; USB drive boot up etc etc; still get same message. Is there a workaround for what seems to be a fairly common install problem?

Therefore I edited the script '/usr/share/initramfstools/ scripts/ casper'. I used the 'dirty hacks'in the ubuntuforums.org/boottoram howto but I suited them for my needs.Now the Systems stops after the kernel and doesn't find a root system.
The sqfs-image without the modification of the 'casper'-script still boots but doesn't load into ram completely.
I've just got a new laptop with 4GB RAM available, in order to fully utilize the available memory I'm going to install Ubuntu Lucid Lynx 64bit, but when I boot with Live CD, I always get the following errors:

i want to use linux but i am having some issues getting it to work on my system. my desktop is a p4 3.4gig with 512 DDR. When I insert my ubuntu CD it starts loading but then i get this screen/message:
Busybox v1.15.3(ubuntu 1:1.15.3-1ubuntu5) built-in shell(ash) Enter 'help' for list of built in commands (initramfs) mount:mounting/dev/loop0 on// filesystem.squashfs failed input/output error Can not mount /dev/loop0 (/cdrom/casper/filesystem/squashfs) on //filesystem.squashfs if I put the same disc into my HP laptop it boots up ubuntu fine. (however it won't allow me to get online, but that is a different issue).
So i insert the ubuntu 10.10 in the dvd and boot it. The menu comes up and i choose to install ubuntu. After that it shows some black screens and this error:
(initramfs)mount:mounting/dev/loop0 on//filesystem.squashfs failed: Input/output error cannot mount /dev/loop0(/cdrom/casper/filesystem.squashfs)on//filesystem.squashfs
The disc aint scratched. I tried installing from Windows but i got another error.
And for some odd reason Ic ant make a removable startup disk:
my friend using XP and it was closed because he didnt activate it . he want to try Linux , i adviced him to use UBUNTU 10.10 ,but after we order the boot we got a loading screen for ubuntu then this error appeared
[code]...
also , the labtop cannot boot from usb coz no option for that in BIOS. what can i do to solve each problems?
so i have done a partition for windows on my MBP, i dowloaded latest ubuntu 10.10 desktop edition, burned the iso , restarted , boted form cd and i get htis error: Whats the problem ? when i try to download the desktop edition it says i need to use a usb stick to install it. does this means that usb stick has to always plugged in?

The usb needs to use the data from the persistent casper-rw, but in the same time not be able to change the casper-rw. I have tried installing ubuntu on a SD-card, and then simply lock the SD-card. So fine so good, but it just wont bootup then - it says "Aufs mount failed".

K3b burned iso with no errors, I set speed at 4x. I made two coasters before getting this far but it still won't get past the BusyBox built-in shell prompt after choosing my language and staring at the xfce mouse for a minute:

I upgraded 9.10 to 10.04 via the web. The program announced it would take several hours, and when I came back to check, computer was off (kids?). Anyway, machine boots and 10.04 starts, but then blinks a few times and goes to a prompt. What should I tell it?
I have a 10.04 disc too, but it won't run from that either (Cannot mount dev/loop0 on filesystem.squashfs failed). Same message when I tried to start a nearby Windows machine with it. Disc "verified" when I made it. What's with that?

is there a way to remove a patch from a kernel?
I need to apply a squashfs-lzma patch (squashfs 4.1cvs) to the liquorix kernel source which is already patched with squashfs 4.0.
how would I do that?I tried googling got this. url
but I dont know the command used to apply the patch the patch is called
35.4-3.patch.gz
url
but that patch includes more than squashfs,etc
I'm trying to install Kubuntu on an old Windows system. I am getting tons of errors such as:
I/O error
SQUASHFS error:unable to read page, block XXXXXX

It then reports that it's loading ACPI modules and starting the ACPI services, starting the system log daemon, doing Wacom setup, starting kernel log daemon.....and then it reads sb_bread failed reading block umptysquat.I have a feeling that this hard drive is toast. I can't get it to install Windoze or Linux. I can't even get a prompt so I can do a low-level format. Unfortunately, I'm not super savvy with Linux and don't know what to do next.
120 GB HDD. All ext4. Wanted to partition it into 60 gig ntfs, and 60 gig ext4 for dual install. Booted up the LiveCD. Clicked on the partition to modify. Selected /windows as mount point. Change took place. Now, my disk shows up as 57 GB FAT (almost all of which is free) and 60 GB of unallocated space. Any way to recover it? I'm sue the data is in the 60 GB of unallocated space. While I have a back up of some of the data, I'm going to be losing quite a bit if I can't recover this...
View 1 Replies View RelatedRecently I was forced to hard reset my computer a couple of times (mostly out of frustration) and due to my idiocy i was confronted with the standard Kernel Panic message at bootup. I tried running an fsck from live cd which corrected a bunch of errors but to no avail (as far as getting rid of the Kernel Panic msg). I then tried to mount the filesystem by accessing it from live cd (and later even installed ubuntu on a small leftover partition to get rid of the annoying live cd lag) but it says that I don't have access to my home or root folder. Mounting from command line gave the same issue.
So now to the question. Is there a general procedure to access data in my corrupt filesystem if it is encrypted?
I have my / partition on an SSD that I formatted in ext3 but I now realise that, in order to use TRIM, I need to be ext4. Can I use Partimage to make and image of the partition, format it (using GParted) and then restore the image? Basically, do Partimage files survive a filesystem change?
View 1 Replies View RelatedI'm about to have a web server at home for the first time. I've always missed having full control and not having to contact my hosting company when I need to do some specific changes - and some changes they won't do for you at all.I've chosen the non-GUI Ubuntu Server with LAMP, and nothing more is installed really except for a couple of command line tools from the repository. The LAMP software has been locked down as good as I can by following some guides on the net and using common sense. Like Apache 2 don't have access to the file system except for the www folder, and setting the headers to Prod. MySQL has skip-networking and I've commented out the listen string to localhost. PHP has a truckload of functions that I've disabled in the php.ini, also by following some guides on the net, among some other security enhancing php.ini editing.
The only thing the server will serve is a well known PHP forum and some html docs, and that's all. Nothing advanced or complicated stuff, and I'm definitely not programming PHP myself or letting anyone do it for me.But I do want to sleep well at night knowing that my server is always on and sitting on the edge of my home network! And can I do that? I've heard that you don't need to be worried about getting your Linux server box hacked, but you should be worried about anyone getting root access to it. But is it really that simple? Ubuntu is shipped without root account and you must have the sudo password, right? What's the odds for anyone to get full access to my system?An issue: I've heard that Apache never must run as root. When I do a ps -ef, I see that there are several www-data processes running apache, but there's one root process running apache too. Is this normal and is it safe?An issue: I've heard that PHP can fail pretty easily. But isn't PHP running under apache 2 and limited by the www-data filesystem access?An issue: MySQL is running as a MySQL user, and I guess that's an unprivileged user right?
I am running a dual boot system with Win7 on /dev/sda and Ubuntu 10.10 on /dev/sdb
I also have a 250 GB disk I use for storing backup data, /dev/sdc
The two logical partitions on /dev/sdc (/dev/sdc2 and /dev/sdc5) each take up 2.86 GB and I would like to free up that space if possible.
Since the filesystem on /dev/sdc doesn't have an OS on it, does it still require that those two logical partitions exist?
On my drive I had 2 partitions for an Ubuntu 9.04 (swap, /) and one partition for Windows. I figured out that I should upgrade my Ubuntu, so I deleted the "/" partition and in its place created 2 new partitions (/, /home) .
After installing the latest Ubuntu 11.04, I realised that although I had backuped everything I needed in a 2nd disk and I could access those folders and their data from my Ubuntu 9.04, both my Windows and the 11.04 can locate neither the folders nor the data now. I have no idea why this happened (perhaps some issue with the mounting?) I have tried the trial version of Stellar Phoenix linux data recovery tool, but it cannot locate the old partitions.
Recently, I started protecting all user-accessible filesystems on my Sidux desktop machine with LUKS. Before that, I would regularly erase traces of deleted data, and I wonder if this is still necessary.
It would be most valuable to me to be pointed towards a good introductory article on the underlying mechanics of LUKS and cryptsetup, as there are a few more minor questions to be answered. Unfortunately, I lack the necessary mathematic and cryptographic background to understand scientific papers.
At boot time, before entering Runlevel 3 the HDD will go mad when mounting tmpfs on /dev/shm...
Code:
EXT3 FS on sda1, internal journal
EXT3-fs: mounted filesystem with ordered data mode
/dev/sda1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
INIT:Entering runlevel 3
It will go on and on at the tmpfs on /dev/shm type tmpfs (rw) until i press ctrl-C...then I will stop whatever it is doing, let the hdd rest a bit, and resume normal boot..
Original disk:
XP NTFS primary
Linux / ext4 logical
Linux /home ext4 logical
Win 7 NTFS logical
NTFS data logical
swap space
NTFS recovery partition
I tried to install linux, as there was a problem with XP overwriting grub, I chose write grub to /dev/sda8 (which is where the linux install was appearing earlier).
I guess this borked the filesystem somehow. Now the NTFS data partition and the swap space are appearing as one free space.
Well actually before that some linux live CDs (including gparted were seeing the entire drive as unpartitioned). I had to go into XP and delete the /ext4 partitions.
Is there any way for me to recover the NTFS data partition ?
I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?

View 9 Replies View RelatedI've made myself a multiboot usb drive and looking to add ubuntu to it. I've created a live system and its respective casper drive, made the changes I want to it and now looking to make the whole system boot to ram including the casper drive so I can use the same usb drive in multiple machines instead of having to have multiple usb pens.
I've added the toram option in the txt.cfg file but only the operating system (filesystem.squashfs) goes into ram so when I take the usb out, the files on the casper drive are lost.
Could you tell me either how to boot the casper drive to ram or how to combine or merge the filesystem.squash and the casper-rw drive.
I have recently been experimenting with installing Ubuntu 10.10 on a USB/Flash drive, and have finally stumbled on the "Universal USB Installer", using a so-called "Casper" file for persistence.Now I wanted to make the Casper file bigger, and found this article:I was reading it, and got confused at this part:"This tutorial assumes that you have already created a bootable USB Flash Drive that contains Ubuntu or an Ubuntu based Live Distro like Xubuntu, Kubuntu, Linux Mint, Crunchbang, etc. You should delete any existing casper-rw file from the drive to free up all available space before proceeding.
1. Restart your Computer, booting from an Ubuntu Live CD"Do they mean that you have to make 1 flash drive that was created with the Universal USB Installer, and has a Casper file on it, AND you have a Live CD from which you operate?If so, could I use one flash drive that acts like a Live CD (without the Casper file), and create another flash drive that DOES have the Casper file, and then boot from the one without, and follow the instructions? (Sorry for the complex sentence, didn't know how other to put it...)
I'm using an acer aspire one netbook and attempting to install ubuntu 11.04 on it using flash drive. I extracted the installer using the universal usb installer. Anyway as soon as I get to the ubuntu installer screen it won't let the installer begin and says this: "could not find kernel img:/casper/vmlinuz. I have tried many things including typing in this:"vmlinuz initrd.img" and extracting the data to the flash drive again but nothing has worked.

When loading it ask for the language that you prefer and then loads.
I would like to have be default to english and boot straight into Ubuntu live.
Also posted another issue that I was having to where when it boots, is displays this:
