I had a look at my install in ubuntu 14.04 and upgraded successfully with the provided procedure.

Now I do see that there is a phratch package (in synaptic) but it can't be installed.

It asks for pharo-vm-core, which is there.

There is a glitch somewhere...

Have you tried this (from this page: http://pharo.org/gnu-linux-installation#ubuntu-ppa-headless-vm ):
Ubuntu (ppa)
Ubuntu users can use the dedicated ppa to install Pharo in various ways:
Install the headless Pharo VM only
sudo add-apt-repository ppa:pharo/stable
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install pharo-vm-core
Install��PharoLauncher, our experimental new GUI Dashboard
sudo add-apt-repository ppa:pharo/stable
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install pharo-launcher
If you don't have the add-apt-repository command,��google��is your best bet as getting it varies by distribution version
For reference, the��ppa page on launchpad.net
