Ubuntu Installation :: 10.10 Over The Top Of Broken 10.04 - Keeping Data
Dec 6, 2010
I had 10.04 in my netbok but something happened, packages failed to install, all sorts of errors when shutting it down, kernel panic when switching on again so I've decided to just install it again. I've got 10.10 running from a LiveUSB drive right now and I'm going through the installer. I want to just tell it to use the exsting partitions, dont bother formatting, just install the new OS on top of the old one so I can keep the user documents etc How do I do this? I picked advanced partition management in the installer, pressed Change on sda1 and gave it a mount point of / but now the "format partition" is ticked and greyed out.. i dont want to format this partition, I just want to install to it

I've finally had enough of Windows and have decided to go with Ubuntu. However I hope someone can help me with this query... I currently have a single hard drive which I have partitioned under Windows into two. The old C:drive holds software & the windows O/S and the D: drive is where I stored photos, documents, etc. Can you tell me if it is possible to install Ubuntu into the old C: partition and leave the d: partition in tact (for a few weeks to ensure I have backups of everything on here). Alternatively, if I add a new drive and install Ubuntu onto there, will I still be able to access the old D: partition (or would I need some kind of dual boot config)?

My friend just got a gaming laptop that he won't let anyone else use (his last one got infected when his girlfriend surfed on it for just one hour -- he refuses to use antivirus since he claims he knows how to keep clean, but he doesn't trust others).
Because I used Linux a bit once, I said to him what if I could promise not to make any changes to your hard drive, and I told him that I was pretty sure I could boot to a live cd and then only write files to a usb key. He's actually willing to let me try (I showed him some linux sites I was looking at, and he believes me that we can do this).
1) Is there anything I either MUST do or else must NOT do to make sure I make no changes to his laptop's hard drive? And so that any changes are only going to go on the usb drive I hook up?
2) Since he's got an i7 processor, I assume I should get a version of ubuntu that supports 64 bits, right?

During a recent request to install fedora 11, I ran into an interesting problem. It seems that between fedora10 and fedora11, the developers switched from fdisk, to parted for creating the initial pre-mke2fs partition table creation.
It looks like the implementation of this is broken, as it's writing the partition table with overlapping cylinder boundaries. While this can sometimes be ignored, it can in certain cases cause significant data corruption.
On an installation I took it through, using the latest installation media, in both manual & automatic partition creation, the layout looked like this:
The last two partitions turn out fine, for some reason. However, those two partitions should not have overlapping cylinders. After my very first installation, the system was completely unbootable, and not even fsck wouldn't rescue it. If this is possible, then that means that a system that's been online for months or even years could simply drop out of functionality simply due to a byte or two of system-critical data falling on that last cylinder. Considering that a lot of the time kernel data ends up on /dev/sda1 (commonly the /boot partition), this is something that should not be ignored.

I'm currently setting up a server with 2x 1TB disks in raid1. (Centos 5.5)In the future, if the storage is insufficient and I decide to upgrade the disks to 2x 2TB, could I just:
- dump ghost image of the array on usb drive
- replace hdd's and build new array
- ghost array with image created previously
Would the above work, will the new partition automatically resize to 2TB or do I need to partition right now with LVM? would it work with LVM?

Intrepid Ibex (U8.10) is what I am using presently and I would like to know if there are measures that I can take to prevent my ISP from keeping data that flows between my PC and it.
I am living in Australia, I am wanting to keep the bastards (read: Australian Government) ignorant about what I use my PC for.
Its them storing any of my personal information that I am worried about, but if I can keep my history from them completely, even better...

the data usage information from the carrier is often several hours old and is accessed in some arcane ways (logging into their website, sending a specific SMS message at best). Here's my idea: single-session data usage is perfectly reported by ifconfig ppp0. The problem is, how tokeep track of previous sessions accumulate the numbers rollover to zero at specified date To be able to do this across computers means that one needs to store it on the modem/SIM card itself. (As a specially crafted SMS message, or a contact).

A while ago my harddrive kinda failed. I didnt notice untill I got "Grub error 17" one time when I was trying to boot my computer. The problem is not really that I couldnt log on to my computer, but rather that I have alot of important information on the computer I would hate to lose. At the time I used Ubuntu 8.04 and had reiserfs filesystem on the computer. I bought a new computer and decided to wait untill I could rescue the data before doing to much dmg to it. But I dont really remember if I tried something to fix it before I realised that it was the harddrive and bad sectors that made me get gruberror 17. Hopefully I didnt do anything.
Anyway. Now today I had some extra time, so I decided to dive in. I booted from a linux mint disk and used ddrescue to transfer all the rawdata over the network to an image file laying on an ext4 drive. Once there I used reiserfsck to try and repair the filesystem. After that i mounted the image file and tried to access the files. Thats where the probelms started. I could see the whole treestructure of the harddrive and everything seemed ok, but when i tried to open the files, none of the pictures, documents and so on could be opend, and when I tried to open stuff like MP3 files they played quite strange. Videofiles was really messy, kept changing resolution and was almost always just gray and green squares on the screen. I decided to use ddrescue and move the files from the image file and on to a clean disk. So when I was done I could mount the filesystem on the new disk, but with the same resault, so I did reiserfsck again, and when that didnt help I did a buildtree also. Still with the same resault. So I decided to investigate the data abit. Opening files at random trying to understand what had hapend. And I saw that some MP3 files (the easiest to open) was some kind of mixing between several difrent mp3 files. Some files wasnt even in the same folder, so it was probably just that the file pointer was pointing at the wrong data on the disk. I dont know how that works really, so I dont know how to go on.
So now to the question. How do I get the data back? Have I done something wrong, can I redo somethig? I still have the broken disk and can take data from it once again, but I want to wait to do that untill I really know what to do. I also still have the image file, and the disk with the copied data. I have a ubuntu 9.10 system at my disposal atm.

computer running ubuntu 10.10 is failing to boot and I want to access the private data in the home folder in order to recover data onto another disk. How do I go about doing this? As far as I can remember its not encrypted but am still unable to access the data to backup.

I have here a Fujitsu-Siemens laptop with Windows Vista on it. The graphical chip of this laptop is damaged in such a way that during boot I can see texts but once the GUI starts it is over. No more picture. This happens with Vista, but also when I boot a live-cd from Ubuntu.The owner of this laptop, not me, wants to buy a new one but would like all data to be saved.I have downloaded the server version of Ubuntu 10.04 (so I stay in text mode) and with the CD I can boot into restore mode. There it is possible to mount the internal hard-disk, after which I can see the data.
But... how do I get it from the disc? How do I setup the network, which I believe is running already, to make the laptop a part of my home network? Now from other computers I can't see this laptop, and I have no idea how to see my computers from this laptop.Or is it possible to burn a CD/DVD in Restore mode. If so how do I do that?

I have a multisession DVD-R with an unreadable volume descriptor caused by a bad DVD burning using growisofs. The DVD is not physically damaged. I tried to recover the data reading directly from /dev/hdc but it throws an input/output error. I believe the error is caused by the broken volume descriptor. That's why I'd like to know a way to make a low-level DVD image that doesn't use the volume descriptor.
Once I have the image I'll manage to recover the data, but now i can't access anything at all. By the way, i've already tried all this programs and anyone worked:
CD-DVD Data Recovery
JuiceSoft Bad CD DVD Recovery
burnaware

I am writing a code in Python where a socket client changes data with the server. That works nice if the connection is up. However it is also supposed to work offline. So I need to be able to detect if the connection is up before sending data, but I was not able to do so. A summary of the code is like that:
Code:
try:
socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socket.connect( (self.host, self.port) )
connected = True
except:
connected = False
if connected:
data = "some data byte"
try:
socket.send(data)
except:
connected=False
socket.close()
If I unplug the cable after the connection is ready then the socket sends data and does not detect the connection failure. What is amazing is that the client detects the connection failure just after the cable has been plugged again. Of course there is a loop in the code above and always that connected==False a new connection is made. How could the program detect the connection failure before sending data and then lead the code to an exception?

Viewing any source on the Web results in partial loading of data followed by broken up multiple lines. It is occurring now with this post. Paging down I get three lines of "submit new thread" until at the bottom are multiple lines (no characters) after "forum rules". I put it to my network provider who cannot come up with any idea of what may cause it. It cannot be the hardware as the same condition exists on two PC's. Both are on 11.2.

I am trying to install the bucktooth gopher server on a Windows xp laptop. I have cygwin 1.7 installed, and I recently installed the xinetd and perl packages. I successfully (?) configured bucktooth, but I have had trouble with the connection cutting out partway through (partial directory listings, half-blank pictures, etc.). I used tintin++ to get the connection's data directly, and found that in addition to occasionally missing lines, some lines are duplicated.
I then ran the bucktooth server directly (to bypass xinetd), and found that the server was giving consistent, correct output. I then added a test service to xinetd (m4), but after connecting to this test service (through tintin++), xinetd would respond with one line of unexpected data (such as "gf" or a line from a recent bucktooth directory listing) and close the connection. Could this be a broken xinetd? My xinetd configuration:

I've had a search through the forums but can't find what I'm looking for, I'm sure it's there and apologies for asking something that has undoubtedly been answered before. I'm running numerous Ubuntu 8 LTS web servers, with mysql, rails, nginx, etc etc and I was after some advice about keeping these servers up to date with security updates. I'm on the ubuntu security announcements mailing list, but I was hoping to find a way to automate the installation of any security updates.

I have a 32g usb stick and I am trying to install Ubuntu on it. But I want to keep 16g as storage space so that I can have it as a normal USB storage for daily use. It's my understanding that I need to create 2 partition ( Since I want to use ext4 for the system which windows doesn't recognize?). But when I created two logical partition and installed ubuntu onto the second partition <sdc6>, I can't seem to boot into there,the screen stays on the white cursor blinking mode, and the usb isn't being read. Is there any way that I could do this? I just want half used as storage and half as Ubuntu system.

I have a server running an older version of Ubuntu and with /var stored on a separate partition on a separate hard drive. I am attempting to update Ubuntu to 10.04, but I still want to store /var on a separate partition and hard drive. However, I don't want to format the drive which currently contains /var, as it has important data.
Is there some way to have 10.04 set up the new /var on this separate drive at installation, without formatting the drive and losing the old /var?

I've recently built a VM appliance using Ubuntu 8.04 that is given to customers for an easy deployment of our software. Ubuntu works great in a VM and its perfect for our software (which is a web application).
Some customers are paranoid (rightfully so) and they will run a vulnerability assessment on the web application. A particular customers' assessment fails as it finds that the appliance isn't running the latest version the Apache web server. I thought that just running "apt-get upgrade" would upgrade all of the software packages to the latest so that failures in the assessment caused by outdated software packages would be resolved... However this is not the case...
I realize that there is a probably a whole process for submitting/approving the latest versions of software packages in Ubuntu, that then get pushed to the repositories - But how does this work? What exactly does "apt-get upgrade" do if it doesnt upgrade packages to the latest?
For example: I need Apache 2.2.11 to fix a particular vulnerability. But when running apt-get upgrade, it doesnt actually upgrade the Apache version number (or any of the other packages). I'm stuck on Apache 2.2.8, and I can't find a .DEB installer for 2.2.11 or later.

I have 9.04 in my laptop and I want to make a clean install of Lynx.
My home partition is sda7 (ext4), so in the partition step during the install I'm telling the installer to use the partition as ext4 but don't format it (I'm explicitly checking sda6 as / mount point and set to format as ext4).
On the next step I see disabled options regarding the access to my home folder and "Require my password to log in and decrypt my home folder" is checked.
My current home partition is not an encrypted partition, so I am not sure of what will happen. I just want it to mount it and access it as Ext4, not encrypt it.
I also have a Private folder in my home partition, what will happen to it? Will I be able to mount it afterwards?

It's been about three days since I've made Ubuntu my OS and I'm quite surprised to see, when I tried it first via wubi, that it actually reads NTFS partitions.It made backing up easy for me though now is it still alright that I still keep them NTFS or should I now start converting them to ext4? Except for my external hard drive.and what's the difference with ext3 and ext4? I was shown these options when I tried formatting my hard drive.
My other hard drive has two partitions which was done when I installed windows a few years back..If I would to reformat should I combine these partitions into one and make new partitions via that?

I'd like to install Lucid on a spare hard drive I have, so I can do my bit for testing it. I have a feeling that if I just burn the latest alpha .iso and install from that, it will replace my current GRUB, whereas I would prefer to simply add the Lucid install as an option in my current GRUB.
Of course I might be wrong, I just wanted to check before I went ahead with it. I was unable to find the info I needed via searching.

Been away for awhile (Fedora 5 or 6 was what I last ran). Just downloaded Fedora10 and installed it on a drive here, running great, looking slick. What drove me back to Fedora (Linux) is my need to create a simulated webserver to locally test stuff without messing up my live site. I had successfully installed php and mysql, using the specific versions my host uses. I then downloaded the RPM of the specific apache instal, followed the install directions and ran into a snag. Last step, says, "$ PREFIX/bin/apachectl start". I did that and received an error. Tried just typing apachectl start, and it worked. Upon my surprise it loaded Apache 2.2 (mine was a 1.3 release), and of course is Fedora-branded.
My questions are as follows:
Do I know somehow how two versions of Apache on? How do I start up the 1.3 one if so?
If not - How can I remove the 2.2, and what will have become of the 1.3 I installed?

I'm wondering if anyone can give me some tips about this.I have very little fedora experiee and wanna start playing with it now.I'v bin using it for some short time a long ago but nothing much.Now I could use some help with this:Can I and how, instal Fedora11, while having Windows7 instaleed allready and then have them both with dual boot. I guess it should be possible but some tips / guide would be great so I don't kill my windows and have to reinstal all over again, as i wanna keep windows as main OS for work but have fedora to learn as well.By the way, I have 2x640Gb in raid0, 1st partition 100gb with Windows7 on it, and the rest on another partition. Both have data on them. If that means anything for instalation

I'm using Ubuntu 9.04 and I want to move to 10.10. The upgrade path would be very long so I want to do a fresh install. I have twisted a little bit my Gnome appearance (theme, icons in menu bar, etc.). I would like to install it, keeping all of my files in my home folder but using fresh visual settings from Maverick.

Having read several threads and received excellent previous advice there are just a couple of points I want to check please before proceeding on laptop. I want to upgrade to 11.4 from 11.2. My disk setup is as follows:-
Disk /dev/sda: 120.0 GB, 120034123776 bytes
240 heads, 63 sectors/track, 15505 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes
Disk identifier: 0x462d462c
[Code]..
If I select existing /home root and swap partitions, format root but prevent formatting of /home and use a different user ID I believe that will leave my existing data intact and will allow me to trial new os. Is this correct approach? If all goes well and when I have new system working correctly, what is best way make old user id date accessible. Can I simply create my old id on new system and will that allow me to access data when I log on with that id?
Second question; at present I have the ability to boot to openSUSE, OS/2 and windoze. (It used to be done entirely by Boot Manager but during my last Linux installation I messed this up a bit so now machine boots to grub and this offers all three operating systems but chain loads Boot Manager if I select OS/2)
When I do the new installation what should I select to retain this setup so that I still have access to windoze and OS/2 but when selecting linux have new 11.4 system run.

I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?

I'm setting up my first Linux install and I was wondering if I would be able to boot Fedora from a CD while keeping every other file on my computer, or in other words if I would be able to put the /boot partition onto a cd. I've also read that Linux can be booted entirely from a logical partition. If that's true then can anyone help me in setting that up. Mostly my problem is I already have four primary partitions, one being a logical drive with plenty of free space in it, and I can't get rid of the primary partitions I already have.
