I have installed KDE on my Ubuntu 12.04 before, and it worked fine for me until I tried to update it. When I tried to update, the Ubuntu Software Center broke, and I can't install anything.

I have asked this on this site but no one answered it. Then I have installed Ubuntu 13.04, and I want to know is it safe and stable to install GNOME 3.8 on my Ubuntu?

If you prefer Gnome Shell, try installing Ubuntu GNOME. Well, notice that Gnome 3.8 is not in the official repos, so the logical conclusion is that it is not a stable setup (unless you uninstall/upgrade Unity, thus it'd be better to just install Ubuntu GNOME). – edwin Aug 1 '13 at 23:41
Every PPA in Launchpad has this warning "You can update your system with unsupported packages from this untrusted PPA..." – NikTh Aug 1 '13 at 23:54
no i asked about installing (adding) Gnome to Ubuntu 13.04 , I checked Ubuntu Gnome site & i don't want just gnome with even no Ubuntu software center & Firefox ! , I want to have choice to select between gnome & Ubuntu in Ubuntu 13.04 start screen (like the way Ubuntu 12.04 was) – HOS Aug 2 '13 at 0:33

I have been running Gnome-shell 3.8 from the Gnome3 Team PPA ( for a number of months now without issue.

If you already have gnome-shell installed, then running the following commands should upgrade to 3.8:

sudo apt-add-repository ppa:gnome3-team/gnome3
sudo apt-get update
sudo apt-get dist-upgrade

OMG! Ubuntu! has a detailed article on installing Gnome 3.8 in Ubuntu:
