In this article I will show you how to install Doomsday Engine 1.14.5 on Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Linux Mint 17 Qiana, Pinguy OS 14.04, Elementary OS 0.3 Freya, Peppermint Five, Deepin 2014, LXLE 14.04, Linux Lite 2.0 and other Ubuntu derivative systems.
Because it is not available via any repository or PPA, we have to download the doomsday deb package from sourceforge and install it by hand. I prefer gdebi over dpkg due to the fact that it also handles dependencies.
Follow the instructions for your system’s architecture exactly, in order to get a successful installation.
