Ubuntu Installation :: Upgrading LiveUSB While Retaining Persistence
Jan 6, 2011
I presently have a Karmc LiveUSB with a casper-rw partition, but am thinking of changing the LiveUSB image to Maverick, while still using the existing casper-rw partition and its data (mostly settings for Ubuntu itself, haven't installed any programmes). Using usb-creator, by the way. Are the config files for Karmic and Maverick significantly different that this will cause any major problems? [Separately, I think this will have implications for my existing Karmic install, because I'm planning to clone my Karmic /home partition to a fresh Maverick install.

I have a USB with two partitions, one FAT32 with Ubuntu 10.04 on it, and one ext4 partition labelled casper-rw. According to the docs this should do to create a persistence installation, but I still get the "can't find persistence medium" error when booting.
Did I do something wrong or is this a bug?
I installed with unetbootin on the FAT32 partition and created the partitions using GParted.

It only takes a few uses of a LiveUSB drive with a persistence file to fully saturate and generate "0 bytes remaining" messages. When this happens, you can no longer use the drive to install Ubuntu until casper-rw is resized or deleted or the USB device is reformatted. I think persistence shouldn't even be an option and that storing files temporarily in RAM is a better solution.

I have ubuntu 8.04 installed on a full disk partition. I've just bought a linux magazine, which came with a CD containing Fedora 12. I want to dual boot or fully install while retaining my music, if at all possible.
I've tried running the Fedora disc and choosing to fill empty space with Fedora, but I get an error informing me that I don't have enough space. Presumably, this is because I have a full disk partition.

I'm about to install a version of Ubuntu onto a 32GB flash drive, I've downloaded are Universal USB installer that will do most of the work for me, however, it asks
Step 4: Select a persistence option for your USB
and the options are
1GB CASPER -RW
2GB CASPER -RW
3GB CASPER -RW
4GB CASPER -RW
What is persistence? am I better off having more (ie 4GB) since my flash drive is a 32GB drive?

i made a persistent Live USB from the Ubuntu Maverick option Startup Disk Creator in the live cd distro. It works really good, i've installed the apps and changes i wanted, but now i'd like to lock persistency so no new changes or any data whatsoever may be stored. Is there a way to disable this capability so it may behave just like the CD adding the changes i made?

I copy the debian-live-7.6.0-i386-standard.iso to the usb. Now i can live boot into the usb.
I also follow the guide "10.3.1 The persistence.conf file" to make /dev/sda2 my persistence partition. When it boot up and i add the parameter "persistence" it will works. But i want to know how to make it automatically boot with the parameter?
My guess is that i have to make my own live cd then copy to the usb again. If that is it, any tutorial how to make live cd from the live cd i already downloaded?

I have searched but have not found a successful way of generating a USB drive with persistence using Debian 8 Live USB.
I have an 8 gig USB drive that I would use 4 gigs for the persistent drive.

I have created a Fedora 15 live usb using LiLi-Usb with a persistence file of 2048mb, on a 4gb flash drive. What I would like to know is two things, will this allow me to update Fedora 15 on the flash drive?, and later, if I chose to install to the hard drive, will the updates cross over?

I have an Eee PC with a dead Hdd. I brought it back to life by installing Ubuntu 10.10 on a 16GB SD card. It works 100% but is sluggish.Now I am wondering, from the standpoint of reducing SD card access and writes, would it have been better to create a Live Disc on the SD card with persistence options? What I am thinking is that a Live Disc is designed to run out of RAM, and would thus reduce the activity on the SD card. The only thing this netbook will get used for is the internet. It is a netbook, so the performance is limited, but as far as netbooks go, it is top of the line with dual core and discrete nvidia graphics.

I tried a while getting a live system working with encrypted persistence. The command
Code: Select alllive-persistence activate /dev/sdx2
works perfect, but boot time persistence works only for unencrypted storage. 'Cause I can not append the boot-log as file the most important part here:
Code: Select all+ tailpid=123
+ tail -f boot.log
+ cat /proc/cmdline
+ LIVE_BOOT_CMDLINE=BOOT_IMAGE=/live/vmlinuz boot=live noeject keyboard-layouts=de components persistence persistence-encryption=luks,none initrd=/live/initrd.img debug=true
+ Cmdline_old
+ PERSISTENCE=true
+ export PERSISTENCE
[Code] ....
The most confusing line is "Warning: cryptsetup is unavailable" - I took a look into the scripts, it checks if cryptsetup and askpass is executable if not this message. But:
I mounted the hdd-img file local and took a look: all binaries there.
So I tried a lot getting it working on boot time. I tried it with live-tools from testing, from wheezy and last but not least installed and pinned live-tools to unstable. Always the same. askpass isn't executable on boot time before mounting the persistence.
Config is
Code: Select alllb config noauto
--apt apt
--bootstrap debootstrap
--binary-images iso-hybrid
--distribution testing
--mirror-bootstrap http://ftp.debian.de/debian/
[Code] .....
(tried with binary-images=hdd, too)
and yes, cryptsetup is inside package-list (otherwise live-persistence from within running machine with crypted partitions would not work). Live tools I used for last run is 4.0.3-1 from unstable, before tried with 4.0.2-1 from testing.
Whats going wrong in boot system?

I'm wondering if it's possible to write changes to a LiveUSB stick. As you probably already know ubuntu gets mounted to a ramdisk to improve performance and save your USB stick's life (I think so anyway, don't quote me on that).
I'm wondering if it's possible to write any changes made, such as changing running services and installed packages back to the USB stick without actually installing ubuntu fully onto the USB stick.

Switched off ubuntu when I installed windows 7 for a bit, didn't have time to learn the intricacies of both systems. Saw the new release and wanted to try it out. Followed the ubuntu instructions on how to install it and make a live usb. Using a 4 GB Sandisk Cruzer straight out of the box. When I boot to the usb, I get to screen that asks whether I want to run ubuntu from the USB, or to install it on my computer. Selecting the run from USB option shows a bunch of commands cycling through for a bit, then the screen goes black and just stays that way. Not really sure what the problem is. Trying to run the 64 bit version fyi.

I dont really use ubuntu too much, just for my programming class. Anyways I want to have ubuntu on a USB stick so I can use it on my laptop, netbook, desktop PC at home and desktop PC in class, all of which run Windows natively.
I would prefer the Virtual Machine (VM) on a USB stick but im not sure if its possible to install virtualbox (my VM of choice) on a USB drive. if not then a liveUSB, though correct me if im wrong but would i be able to save files on a liveusb?
If I do go with the VM on the usb stick option, i need an idea what size USB stick to buy so what is the bare minimum space you can run ubuntu on? I also intend to run OpenSUSE which is why i prefer the portable vm option.

I created a LiveUSB and that worked. On about the 3rd use I attempted to update packages - about 174 came up I think (I saw that number on another post which reminded me, hence the precision). Two or three dialogues came up, unfortunately unintelligible to me, a Ubuntu novice. Both concerned grub2. The first I just forwarded on and the update trundled on. The 2nd asked me something like whether I wanted grub to update sda or sdb. I checked neither (against the pop-up help advice). The update completed but when I eventually went to reboot from the USB I got a repeating fatal message: something like "Could not load /lib/modules/2.6.31-17-generic/.dep". I had to switch off. It did reboot successfully from a LiveCD.

im not very educated in amd processors, but i think that they are all 64-bit processors.
i downloaded the amd ubuntu 9.10 into my computer, and used the usb maker utility in the system menu. i put in in my new pc (it was given to me), and i tell it to boot into the usb.
then i get this. i am posting a pic.
sorry about the sideways pic. i took it with my phone.
anyway, i get the syslinux boot shell script thingy. i have tried lots of things. linux, vmlinuz, lots of other things i found online. so what im wondering is the exact name of the kernel in ubuntu 9.10 amd version.

I am using ubuntu 9.10...now I have created an USB startup disk in my 1gb pen drive with a persistence region of 200MB. But after I have booted into the live ubuntu version using the pen drive how will I access the reserved space?.. I have tried mounting the pen drive but still couldn't access the reserved space.
NB:-I have only one FAT32 partition in my pen drive...

I'm quite keen to get Fedora 15 up and running but I am falling at the first hurdle. I can successfully boot from a LiveUSB and be presented with a text only tty2 / tty3 / tty4 / tty5 interface inviting me to log in but no graphics are possible and I cannot see any way to install Fedora. I have GMA500/Poulsbo graphics chipset which has notoriously **** Linux support but I note that basic support has been inlined in 2.6.39 so I think that if I could only get Fedora installed and then upgrade the kernel or do other things later I will be ok.

I experienced what i perceive as the craziest thing during 2 years of using ubuntu. About some months ago, I have two ubuntu installed on my HP-mini netbook: ubuntu 10.04 64 bit (CAElinux) and kubuntu 10.04, and run without problem.
One day, the netbook's battery run out of charge and I forgot to plug it in. The ubuntu, as usual, went to hibernate, but without harddisk noise, so I forced it to shutdown by pressing power button (as i think it is not normal). What happened later was the partition of 10.04 was broken, it could not boot, it even affected another partition as the netbook couldn't boot kubuntu 10.04.
I try to run liveUSB and CD of both distro and the liveCD/USB boot stopped on loading screen. So I try another linux distro: PCLinuxOS, which was able to boot but took very long time. The partition of ubuntu 10.04 could not be accessed.
After installing PClinuxOS in replace of kubuntu, I scanned the ubuntu 10.04 partition and the partition was fixed, I could access the partition and could load to ubuntu 10.04, but it took very long time. Here how it loaded: first: blank screen with blinking cursor, then ubuntu load screen, then back to blank screen with blinking cursor, then it showed numbers and sentences, like some scanning works. It took long time before login screen appeared (about 10-15 minute, while the prevously normal boot time in my netbook was less than 1 minute), but once its done, the ubuntu worked normally. This also the case in the PClinuxOS and the reason it load very slowly.
After this, I try to boot the liveUSB of various linux distro, and found some could boot while the others not:
Able to load with unusual slow boot time:
PClinuxOS (latest)
Ubuntu 8.04
Fedora (latest)
Linuxmint 8 (based on ubuntu 9)
Can't load
ubuntu 10.04 and 10.10
kubuntu 10.04
latest linuxmint
The liveUSB boot could take 1 hour. I also try the latest Puppy, Gentoo and OpenSuse liveUSB but it couldn't boot, and it likely the liveUSB problem. I made the all the liveUSB with unetbootin. The ubuntu 10.04, 10.10, kubuntu and the latest linuxmint could not boot even after I scanned the ubuntu 10.04 partition. There was no problem with the liveUSB as it would load normally on another computer. I think it is just the variant of ubuntu 10 that is not being able to boot.
I was not content on this slow boot, so I try to format the two partition of ubuntu and PClinuxOS (there are another partitions though), and installed ubuntu 8. But it also happened to boot slowly as the previous ubuntu. Then I replaced it with linuxmint 8, and the same occurred. So I try to install windows on another partition, and it boot normally.
The question is, what is happening. Why do the forced-shutdown-of-ubuntu-10.04 affect another partition, to the boot of another distro? If my HD was broken, the Windows would load very slowly too right? Yes, in SMART Data (from disk utility) it showed "few bad sector", but i think this is not related to the slow boot. The ubuntu 10.04, 10.10, kubuntu and the latest linuxmint cannot boot until this moment. I am thinking there are some informations planted on my computer, that twist it to load some distro slowly, and prevent it to load some others. But where and what? (I almost arrived to the thought that this is supernatural!)
Because of my long story up there (as I think it must be reported), the conclusion is:
1. Ubuntu 10.04 on my netbook was forced shutdown (by me)
2. It caused the partition broken
3. After fixing the partition (by scan, but I forgot the command), it took very long time to boot, but the ubuntu itself run normally
4. It also affected the boot of another distro (slow down the boot time), but Ms.Windows boot time is normal
5. It also caused ubuntu 10 (and its variant) to not be able to boot from liveCD/USB
6. It also caused me going crazy
Now im gonna format the whole HD in hope of ubuntu 10.04 (and later) could boot again, but shall it fix the problem? (as formatting the previously ubuntu 10.04 partition did not solve the problem). Or should I buy another HD (or even computer) to install natty!

I booted into the Fedora 11 on my netbook, and used the desktop icon to install to hard-drive. I specified to use "Free space", and hit next. From there, it just stalls. The "Install Fedora" window does nothing, and I'm going on a half-hour now of nothing.
Tried three times, still nothing.
The first time I tried, I chose to replacce old linux installation (ubuntu), and when I told it to install Fedora 11 root as ext4, it said the boot can't be ext4... so I chose ext3 and it said root device must be ext4...

I have a Win vista dual booted with ubuntu, no problem there, all's well. I used live-usb to make a bootable USB with centos 5.0 I created the usb and it will boot just fine. The problem I run into is updating the installation with the package manager. I run the manager and the system prompts for reboot and I get this error:
