How can I upgrade from 12.04 lts to raring?

[jinjorge]

There is a standard method that we used when the new development cycle started. We took an updated Quantal and changed the software sources/repositories to Raring.

This is how I got my Raring install in the first place back in November. and being unable to get a Raring ISO image to work I converted a second Quantal just the other day. A lot of updates need to be done but it will still work.

sudo sed -i 's/quantal/raring/g' /etc/apt/sources.list

That changes the repositories. Follow it with the usual

sudo apt-get update

sudo apt-get upgrade

I am planning later today to install Gnome Remix. That will be Quantal and then use this method to convert it to Raring. If it does not work in this case I can easily re-install the 12.10 Remix.

Regards.

This is pretty awesome!!! Used it to go from quantal to raring.

Thanks for sharing.

Downloaded a fresh copy of 12.10 and installed it in VB. Then, using the above sources list line, I changed sources list to raring.

Ran into problems with broken dependencies after running all regular updates, including dist-upgrade.

ran the following two lines:

   sudo dpkg --configure -a

  sudo apt-get -f install

These fixed dependency problems and allowed for the installation of the 3.7 kernel and the remaining upgrades.

I already had Raring running in VB but wanted to give this upgrade method a try and was frustrated until I stumbled upon the 'dpkg' line above.

Thanks, Graham, for providing the sources list info.

Graphical way (bypass the bug):

do-release-upgrade -d -f DistUpgradeViewGtk3
