Ubuntu Installation :: Version Upgrade - Reinstall - Preserve /home Method?
Sep 18, 2010
I will be version-upgrading a friends (Ubuntu only) laptop very soon. It is 9.04 now and the new version will be (ideally) 10.04.1 The machine has a large unused area on the hard drive and who has known this situation was to use the uncommitted area to do a complete new install of 10.04.1, leaving the 9.04 unchanged (useful insurance). Then, copy, paste (?) the /home directory from the 9.04 into the newly completed installed 10.04.1 overwriting the installed directory.
Opinions seem to support the notion that such a paste into 10.04.1 is likely to be successful and trouble free as long as the 10.04.1 installing username is the same as the 9.04 username with same privilege level. I would be grateful for comments here, particularly with any details, gotchas, you can see.

I am now using ubuntu 10.10. I am going to install ubuntu 11.04 on April 28 (after it is released). I want to preserve:
1) the list of extra programs installed by me on ubuntu 10.10 (I want to install the same programs in 11.04 also)
2) program settings
My questions:
1) From synaptic package manager menu:
File -> Save Markings (save full state, not only changes)
saves in a text file the list of programs installed on my system. I used that file to install the same programs in several computers running ubuntu 10.10. Is there a way to use that list in 11.04 also.
2) Copying the directory ~/.mozilla preserves all settings of firefox from previous installation. Like that what files should be copied for gnome applications (gnome-panel, nautilus, etc.)

I have been out of the Linux loop for a while. Prior to the holidays I did something 'stupid' within Wine and ended up taking out my Ubuntu partition to the point where it wouldn't boot. Being that I have a triple boot system and I had plans for the holidays, I didn't want to risk a reinstall in the event that if something went wrong with Grub, it would render my whole system useless. So I waited until now to reinstall Ubuntu. I performed the reinstall this past weekend and for the most part I thought everything went fine, but I noticed something was different with the file system.
When I attempted to load a 3.5gig program into Ubuntu yesterday, I got an error message saying that I don't have enough disk space. I said to my self, "That is impossible as I have a 106gig partition for programs". I have a separated system in which Ubuntu /root has an 8gig partition and the Home partition supposed to be the 106gig drive. I did this in the event I had to reinstall, I wouldn't loose my information. Well apparently something went wrong with the install and it appears that I have two Home folders...one is on the 106gig drive and the other is in the root directory.
Making note of that explained why my program wouldn't load because the root partition is only 8gig. So, my question is this: Can I set Ubuntu back to the old Home directory, or do I have to reinstall once again? As what under my avatar says, I am on Ubuntu Studio 8.04 (Hardy Heron). I stuck with this older version because it has long term support. I have a triple boot system with Windows XP, Puppy Linux, and Ubuntu Studio. I have two SATA 500gig drives with the first drive being home to all the operating systems and programs. The second drive is just for data.
Here is my fdisk -l I put the partitions usage in parenthesis:
geo@ubuntu:~$ sudo fdisk -l
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000cf364 .....

I installed Mythbuntu, got some Wine apps up and running, then discovered my Nvidia DualTV MCE won't work with Myth. So I'd like to try a different variant, either the plain vanilla Ubuntu or UbuntuStudio.Can I just use Mythbuntu to create a new partition, move /home/* to it, and then reformat and install over the original Mythbuntu partition? When I reinstall the new version, how do I tell the installation process to use /home on the other partition (without overwriting it) instead of creating a new one from scratch?

I'm wiping out / on an Ubuntu box but want to keep everything in /home/, which is mounted on a different partition. Using Code: ecryptfs-unwrap-passphrase ~/.ecryptfs/wrapped-passphrase I have unwrapped the passphrase, resulting in a ~25 character alphanumeric string. Is it possible for me to install from a disk and give the installer the (current) passphrase so that it will automatically mount my home directory?

I have installed Ubuntu 10.10 desktop version on my Lenovo L420 laptop. Now my friend told me that if I had installed laptop version on it then it would have recognized events related to laptop like closing down the laptop screen and all.
Q1. Is there any way by which I can upgrade it to laptop version?
Q2. What are the differences between both?

How do I ensure that my home partition does not get deleted the next time I reinstall Ubuntu, as I can see there is a choice between formatting the whole drive and manually partition it, but if I reinstall won't I delete the home partition as well?

I tried to install rawhide by enabling the rawhide repo and doing a yum update. Lets just say it didn't go so well. My system wont start the GUI when I start the computer. It just shows the Fedora boot animation and stays there. So anyway I need to reinstall Fedora 14. I wanted to reinstall Fedora without having to backup and restore all my data (my home directory). So I did some Googleing and found that if I had my home directory on a separate partition that I was set to go. All I had to do was format "/" and just tell it to use the "/home" partition I already had and not to format it and I that was it. So I went to try it myself and found that it was not as straight forward as it seemed. Well at least for me.
I clicked on "lv_root" assuming that was supposed to have "/" as its mount point. I clicked the edit button. I selected "/" as its mount point and told it to format it as ext4. Then I clicked on lv_home and clicked on the edit button. I made its mount point "/home" and clicked "ok". I clicked "Next" and I get this error "Bootable partitions cannot be on a logical volume". What do I need to do to fix this? I assume this has to do with the "lv_" at the beginning of the partition names.

Ok. I have a media server running debian amd64. when I installed it I made separate partitions for root (/) home (/home) var (/var) and swap.
I'm adding some new hardware (mobo and ram) and want to reinstall debian. I would like to keep my home and var partitions intact and just reinstall everything in root (/) partition.
I'm unsure of how to do this during the installation. Do i need to format? how do I tell it to use the /var and /home partitions?

I wanted to upgrade qbittorrent to the newest version. So I went to the official website and followed the steps of typing some commands in the terminal. However, it said missing libtorrent-rasterbar5. I went to Synaptic and checked, showing "libtorrent-rasterbar6". Does this mean my version of libtorrent-rasterbar is too new?
And I've removed something regarding qbittorrent because I wanted to install rasterbar5. I searched for rasterbar5 in the Net and downloaded it. It connected to the Ubuntu Software Centre automatically but it showed unable to install.
So I thought I failed to upgrade qbittorrent. I just wanted to install the original version (v2.4.0). I did it like the first time I downloaded qbittorrent. Open the Ubuntu Software Centre and search for it and press "install". It failed! Because a type of repositories named "qbittorrent" showing conflict.
I've dealt with a similar problem regarding GIMP successfully before. But I can't remember.

I upgrade to fedora 9 from fedora 8. After upgrading I still gets F8 modules appear when I used system update. It seem that my Fedora 8 installation has a know bug that updates are halted, and this problem is not resolved during OS update. Since I have not install any other software yet I would like to make a clean installation of fedora 9. How can I remove the fedora 9 from my hard drive and make a fresh installation?
I use GRUB as a boot loader and have window install as well.

Had a working WinXp/Karmic dual boot system. Tried to upgrade Karmic to Lucid and my daughter rebooted the system during the upgrade. I decided to do a fresh install of ubuntu, leaving Windows in place and it succeeded until the end when it said it could install the bootloader, so I proceeded without. I meant to say "it said it couldn't install the bootloader, so I proceeded without.
On booting, Grub drops to the command line.
I get grub>, not grub-rescue>
I did ls in grub and it showed the partitions I expected
/sda5 is /boot
/sda6 is /swap
/sda7 is /
/sda8 is /home
I tried to follow the grub2 command line manual by entering
Code:
set root=(hd0,7) (success)
linux /boot/vmlinuz-2.6.32-24-generic root=/dev/sda7 ro (failed - couldn't find file)
so I'm now a bit stuck.
Here are my bootinfo_script results (by the way, sdb is just an e-SATA hard disc with nothing installed on it, I don't know why bootinfo thinks Windows is there. Windows is on /sda2 with some sort of backup/recovery partition on /sda1)
Code:
Boot Info Script 0.55 dated February 15th, 2010
Boot Info Summary:
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #7 for /boot/grub.
=> Windows is installed in the MBR of /dev/sdb .....

A much older version of the program compiled against GTK 1.2 works on CentOS 5.3
A current version of the program, compiled against GTK2, works in Slackware 12.1, 12.2 and 12.3. But I have a failure (see below) in CentOS 5.3.
The GTK library for each dist is
libgtk-x11-2.0.so.0.800.20 for Slackware 12.1
libgtk-x11-2.0.so.0.1200.9 for Slackware 12.2 and 12.3
and
libgtk-x11-2.0.so.0.1000.4 under CentOS 5.3
I have had the software working on different versions of GTK as well but no longer that that version information available.
(Below) -- I believe I've narrowed it down to the function gtk_entry_set_text in some (but certainly not all) instances.
I could provide details, but I doubt they really matter. My best guess is that libgtk-x11-2.0.so.0.1000.4 is broken. So, I'd like to replace it without learning how to compile gtk from scratch or causing problems with the rest of CentOS.

The first is regarding my home network that I've setup. It mainly consists of two laptops, both running fedora. I find myself using rsync, ssh, scp, and the like quite often, but it is very annoying constantly needing to provide a password. This sounds like a job for RSA keys, but is it safe to do so on my laptop I take whenever I travel? If my laptop were to be stolen, my personal and private keys would be available to the thief. Is it instead better to use something like kerberos (which I'm not very familiar with, ie. I've used it at work but never took the time to learn how it works).
This isn't much of an issue with my home network since it is protected behind my router. However, I have the same issue with rsync, and ssh to my work PC. These are the RSA keys I'm worried about if my laptop were to be stolen.

Does Ubuntu can / support update automatically like Windows Update does ?it is simply because I'd like to standardize my Ubuntu server installation across the datacenter to be exactly the same (latest) rather than having multiple minor version.Or is it possible to script / cronjob upgrade Ubuntu 10.0.4 into 10.10 using apt-get command by checking to the repo

So I was messing around trying to uninstall Nibbles and reinstall since I have an issue starting that game and something happened and removed the submenu under Games called "Logic", which had another whole list of games.
Is it possible to reinstall the games package or reinstall the update?I'm thinking more of the lines of a system restore or something so back 2 days from today.

I upgraded the computer at work from 10.10 to 11.04 yesterday and that went okay. Some issues, but I can work them out. I thought I'd get the computer at home done yesterday too, but that failed. I'm now operating off of a USB drive. I also have Windows7 that I was able to function off of (probably have 3 hours logged on Windows in the last 4 months). Anyway, I have an AMD64 with 4 hard drives, of which we have 2 RAID settings so it's more like 2 hard drives.

currently my installation is on sda1, while /home is on sdb1. I'd like to wipe sda1 and reinstall Ubuntu 10.04 from scratch.
Can I just run the 10.04 installer, reformat sda1, install 10.04 over it, then follow a guide to remount sdb1 to /home (and chown the new /home)?

I just need some clarification on the best upgrade path for me. I currently have Karmic installed with a separate partition for /home. I want to do a clean install of lucid with the CD.
What's the safest way to ensure my /home partition remains untouched? Should I install lucid overtop the karmic partition and then indicate a mount point for the other partition? or should I leave /home alone completely during installation and then just manually configure the mount point after install?
Edit: I had previously upgraded from jaunty to karmic via the update manager. This worked well but Karmic has felt very buggy overall so I feel a clean install might be best. although the audio is silent when the live cd boots :S
