Upgrade to or Install Cinnamon 2.4 in Ubuntu
If you favour stability you should not upgrade to Cinnamon 2.4 in Ubuntu yet. New releases of Cinnamon arrive a month before Linux Mint for the specific purpose of testing, ironing out bugs and gathering feedback.
But if the above sounds more like a reason to try rather than avoid, Cinnamon 2.4 can be installed in Ubuntu 14.04 LTS and Ubuntu 14.10 using the following Cinnamon nightly PPA:
sudo add-apt-repository ppa:gwendal-lebihan-dev/cinnamon-nightly
Followed by:
sudo apt-get update && sudo apt-get install cinnamon
Already have Cinnamon installed? I’d advise running the following command in lieu of the one above. This will ensure that any package conflicts are automatically resolved by the package manager:
sudo apt-get update && sudo apt-get dist-upgrade
Installed and want shot? That’s easy enough; you can remove Cinnamon 2.4 and the bulk of its configuration files, dependencies and cruft by running this command:
sudo apt-get purge cinnamon
