Hello Linux Geeksters. As you may know, Plank is the default dock app on Elementary OS 0.2 Luna, but it can be easily installed on other Ubuntu based systems, enabling the users to place their favorite apps in the dock, for an easier usage. The latest version available is Plank 0.6, which has been released a while ago. For a list of fixes and improvements brought by the latest version of Plank, see the official release notes.
In this article I will show you how to install Plank 0.6 on Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Ubuntu 13.10 Saucy Salamander, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 17 Qiana, Linux Mint 16 Petra, Linux Mint 14 Nadia, Linux Mint 13 Maya and Elementary OS 0.2 Luna.
Because it is available via the PPA, installing Plank 0.6 on Ubuntu, Linux Mint and Elementary OS is easy. All you have to do is add the ppa to your system, update the local repository index and install the plank package. Like this:
$ sudo add-apt-repository ppa:ricotz/docky
$ sudo apt-get update
$ sudo apt-get install plank
Optional, to remove plank, do:
$ sudo apt-get remove plank
Or, you can disable the PPA, remove plank and downgrade all the packages updated via that PPA, do:
$ sudo apt-get install ppa-purge
$ sudo ppa-purge ppa:ricotz/docky
