I used the 12.04 minimal installation image/ CLI installer to install the base operating system. Once the base system was installed I did the following:
sudo apt-get install python-software-properties sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo add-apt-repository ppa:xorg-edgers/ppa sudo add-apt-repository ppa:gnome3-team/gnome3 sudo apt-get update sudo apt-get upgrade
At this point there were system upgrades which were downloaded and applied. I went on to install xorg nvidia-current gdm gnome-shell synaptic. Every step of the way I'd check for "upgrades" and after the initial bout of upgrades nothing was ever upgraded.
Once I rebooted, logged into the gnome desktop environment and started synaptic, however, on Mark All Upgrades Synaptic said:
To be upgraded linux-headers-generic linux-image-generic
It seems like that should've been upgraded during the installation, yes? But I'm using ppa which draw software newer than that which is available in Synaptic.
Will I downgrade the ppa installations I've already applied to the system by running the aforementioned upgrade through synaptic?
