Ubuntu – How to upgrade to a newer release of Ubuntu using the Live CD

installationlive-cdupgrade

I've downloaded Ubuntu 13.10 daily CD and I want to upgrade all my computers using this Live CD (they all run Ubuntu 13.04 presently).

How can I upgrade to Ubuntu 13.10 exploiting the packages in the CD? Is there any standard procedure for this?

I tried this:

I rebooted into Live CD, searching for an option like "Upgrade from 13.04 to 13.10" (I think it used to appear in the alternate CD) but found nothing like that. -EDIT- Even if the option is not present it is possible to "mimic it" by entering manual partitioning and tell Ubuntu to reuse the existing partitions without formatting them. Ubuntu will keep user's data and install the updated software. Nevertheless this is not a viable solution because after the upgrade one has to reinstall all the programs he needs, since it is like having a vanilla Ubuntu.
I booted into Ubuntu 13.04 and added the CD to my software sources. I then proceeded with the upgrade however the CD was never accessed and everything was downloaded from the web.

I know, I know… I have other options rather than using the Live CD, namely:

Forget the CD and setup apt-cacher in the LAN
Copy the deb files from the CD into /var/cache/apt/archives/

But this looks unreasonable to me… Why can't I insert the CD and exploit its contents? I would like to avoid apt-cacher and if possible avoid also manually copying the packages.

Any idea on how to accomplish this?

You need the Alternate CD/DVD, which has all the packages required to perform upgrade. In other words, it is a replacement for the on-line access to Ubuntu repositories.

The Live CD contains only the current version of Ubuntu and its packages and just copies that over to your drive after dealing with partitioning.

It's bad news, I'm afraid. Canonical removed the ability to upgrade using CD/DVD images from the 12.10 release.

All of the instructions I have seen for upgrading to 12.10 only talk about a network installation, usually using the Update Manager. See the 12.10 release notes. It is also mentioned in the 12.10 Beta2 Technical Overview, and there are lots of comments and complaints out there on the net.

Ubuntu – How to upgrade Ubuntu to newer release manually (without using update manager)

Let me say, I wanna upgrade to Trusty directly from Raring skipping Saucy. How do I do that?

Fully upgrade your existing installation.

sudo apt-get update && sudo apt-get dist-upgrade

Disable all 3rd-party applications & PPA (especially xorg-edgers!!!)
```
sudo sed -i s/deb/#deb/ /etc/apt/sources.list.d/*.list
```

Change release and update:

sudo sed -i s/raring/trusty/ /etc/apt/sources.list
sudo apt-get update

(Most cautious part starts here) Upgrade:
```
sudo apt-get upgrade
sudo apt-get dist-upgrade
```
During this, you can experience errors!!!. That's normal. To fix, simply run sudo apt-get -f install and the command was running before. Until success on dist-upgrade.

Also, you will be prompted to replace some configuration files. Keep the files you manually configured and replace those configured by scripts.

Reboot and enable repositories you disabled:

sudo sed -i s/#deb/deb/ /etc/apt/sources.list.d/*.list

You may want to disable sources. Run

sudo sed -i s/deb-src/#deb-src/ /etc/apt/sources.list.d/*.list

Update release name in repositories and update

sudo sed -i s/raring/trusty/ /etc/apt/sources.list.d/*.list
sudo rename s/raring/trusty/ /etc/apt/sources.list.d/*.list
sudo apt-get update

Replace non-working repositories with previous versions and update

sudo sed -i s/trusty/saucy/ /etc/apt/sources.list.d/jwigley-window-list-trusty.list
sudo sed -i s/trusty/saucy/ /etc/apt/sources.list.d/playonlinux-trusty.list
sudo sed -i s/trusty/saucy/ /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list
sudo apt-get update

Finally, dist-upgrade:
```
sudo apt-get dist-upgrade
```

Voila! The system is fully upgraded! To finish, delete old kernels and obsolete packages through Synaptic.
