There will be no updates. I am not sure if the development branch has opened up yet for 12.04

To upgrade there are no iso's at this stage.

to upgrade to the development branch you need to do the following

1) install update-manager-core
2) sudo do-release-upgrade -d

the 2nd step begins the upgrade process to the development branch.

Hi,

I did the following steps :

https://wiki.ubuntu.com/DebootstrapChroot

https://help.ubuntu.com/community/VirtualBox/FirstVM

Those leads me to the following questions :

Where can I find an iso image for 12.04 (Development branch) to run in
the VirtualBox, do I have to generate it myself ?

How can I test Unity in 12.04 (Development branch) ?

Is it possible to test it starting from a tty session in 12.04 (sudo
chroot /var/chroot/precise) and then starting the gui (lightdm) ?


Thank you very much.

Have a nice day.

I did "sudo update-manager -d" on a separate partition to get Ubuntu
development release.

Right now, this is what I got back from issuing the command :

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.10
DISTRIB_CODENAME=oneiric
DISTRIB_DESCRIPTION="Ubuntu 11.10"

How do I upgrade to 12.04 (precise) ?
I don't believe you can upgrade to a development release using the"-d"
switch to upgrade-manager until after Alpha 1 has been released. Of
course, you could always change the entries in /etc/apt/sources.list
manually to point to precise.

Do I need to switch to 12.04 (precise) ?
Not at all. At this point in the development cycle, I would even
suggest that it would be a bad idea to upgrade you main work
environment. I suggest would suggest that you use a virtual machine or
go back over some of the options in the
UsingDevelopmentReleases/OtherWays wiki page. Many Ubuntu developers
prefer to build their packages with pbuilder
(https://wiki.ubuntu.com/PbuilderHowto) and then test them in a
virtual machine.
