This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Add repository

sudo add-apt-repository ppa:elementary-os/daily

Update and install

sudo apt-get update

sudo apt-get install elementary-desktop

Thats it, now log out and on the login page, the Pantheon desktop should be visible in the list of desktop environments.

    This answer is now obsolete, as the ppa no longer provides packages for 15.04 – RolandiXor Sep 20 '15 at 6:15

Okay, for this answer, I'll follow the advice of Guss who managed to successfully install pantheon on Ubuntu 15.04.

  • First of all, rebuild ubuntu-extras-keyring locally following these commands:
mkdir ubuntu-keyring && cd ubuntu-keyring
sudo apt-get install -y debhelper
wget http://archive.ubuntu.com/ubuntu/pool/main/u/ubuntu-extras-keyring/ubuntu-extras-keyring_2010.09.27.{tar.gz,dsc}
tar -xf *.tar.gz
cd ubuntu-extras-keyring-2010.09.17
debuild -i -us -uc -b
sudo dpkg -i ../ubuntu-extras-keyring_2010.09.27_all.deb
  • Guss then goes on to mention: "After that, elementary-desktop will install, but will error out at the end because it depends on systemd-shim which is no longer needed nor wanted with 15.04 having a full SystemD implementation. " --------- Once you get this error, do the following:
sudo dpkg --force-depends -r indicator-datetime
sudo apt-get purge unity-control-center unity-control-center-signon

Pantheon should now be installed on your system.

  • I am tempted to try what you've mentioned here, except it doesn't make straight sense. elementary-desktop will install from where? And where is the advice that Guss mentioned? (You just linked to his profile). And that last pair of commands... why would I want to run those? – RolandiXor Sep 22 '15 at 18:17

    I found his answer and only now realized that this question should be marked as a duplicate. I did not find the other question before. – RolandiXor Sep 22 '15 at 18:20
