1. title Upgrading Feisty to Gutsy

<< < Edgy Gutsy >>

7.04 to 7.10 (Feisty to Gutsy)

Before you start

Please make sure you've read and understood the main EOLUpgrade page. I would recommend using clonezilla for backing up your current installation. It is very easy to backup and restore your partitions with clonezilla. It takes less then 30 minutes to backup/restore a 20Gb root filesystem which has 4-5 Gb used space.

Requirements

• /etc/apt/sources.list

Please make sure you have the following sources.list.

# Required
deb http://old-releases.ubuntu.com/ubuntu/ feisty main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ feisty-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ feisty-security main restricted universe multiverse

# Optional
#deb http://old-releases.ubuntu.com/ubuntu/ feisty-backports main restricted universe multiverse

You can make use of -backports, -proposed repositories if you want. For more information about repositories see Repositories/Ubuntu.

The upgrade

• Make sure your sources.list is correct (see requirements)
• Update the package list and get fully upgrade all packages

sudo aptitude update && sudo aptitude upgrade

NOTE: It could be that you just upgraded your kernel, if this is the case, please reboot!

• Upgrade your complete system

sudo do-release-upgrade

This command will fail, because it cannot download a specific tarball which is needed to the upgrade, this is due to an error in the meta-release file. it will however leave a subdirectory in /tmp, owned by root.

    fileobj = file(name, mode + "b")
IOError: [Errno 2] No such file or directory: '/tmp/tmpaIgInN/gutsy.tar.gz'

• Download the tarball manually

First we will make sure we can create and write into the /tmp directory do-release upgrade created. Then we download the gutsy tarball and extract the contents.

sudo chown $USER /tmp/tmpaIgInN
cd /tmp/tmpaIgInN
wget http://old-releases.ubuntu.com/ubuntu/dists/gutsy/main/dist-upgrader-all/current/gutsy.tar.gz
tar zxvf gutsy.tar.gz

• Make sure we can continue upgrading, since two packages are needed we need to change the prerequisites sources as well:

perl -p -i.704 -e 's/(http:\/\/).*archive(.ubuntu.com)/${1}old-releases$2/' prerequists-sources.list

Problems with installing specific packages:: Some users have reported that they still have to download packages from archives.ubuntu.com while everything resides on old-releases. If you have this problem, you could change your /etc/host file to point archive.ubuntu.com to old-releases. Do this by running `host old-releases.ubuntu.com | grep address | awk '{print $NF"\tarchive.ubuntu.com"}' | sudo tee -a /etc/hosts`. After the upgrade you need to remove this line again from the hosts file, by doing `sudo sed -i '$d' /etc/hosts`

• Change your sources.list

sudo perl -p -i.704 -e 's/feisty/gutsy/g' /etc/apt/sources.list

• Continue the upgrade process

sudo ./gutsy --frontend DistUpgradeViewText --mode=server

• Check your new version

Reboot your machine and you can now run `lsb_release -a` to check the new version of Ubuntu. << < Edgy Gutsy >>
