Hello Linux Geeksters. As you may know, Subsurface is a diving log application, written by Linus Torvalds himself. The latest version available is Subsurface 4.2, which has been recently released, coming with a bunch of bug-fixes only.
In this article I will show you how to install Subsurface 4.2 on Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Pinguy OS 12.04, Elementary OS 0.3 Freya, Elementary OS 0.2 Luna, Peppermint Five, Deepin 2014, LXLE 14.04, Linux Lite 2.0 and other Ubuntu derivative systems.
Because it is available via PPA, installing Subsurface 4.1 on the listed Ubuntu, Linux Mint, Pinguy OS, LXLE, Elementary OS, Peppermint, Deepin and Linux Lite systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the subsurface package. Like this:
$ sudo add-apt-repository ppa:subsurface/subsurface
$ sudo apt-get update
$ sudo apt-get install subsurface
Optional, to remove subsurface, do:
$ sudo apt-get remove subsurface
