Terminix (update: it's now called Tilix) was uploaded to the Debian Sid repositories recently. To make it easier to install and stay up to date with the latest Tilix versions, I used the official Debian packaging (thanks to the packagers!) and created a Terminix / Tilix PPA for Ubuntu 16.04 and Linux Mint 18.
Update: the PPA now also provides packages for Ubuntu 16.10.

Ubuntu 16.10 Yakkety Yak did not yet import ldc 1.1.0 from Debian, required to build gtk-d (Terminix dependency), and it failed to build in my PPA for Yakkety (probably that's why it's not in Yakkety yet). Also, since Tilix requires GTK 3.14, it can't be built for Ubuntu 14.04.
The PPA package (as well as the official Debian package) is only available in English because the locale files are not built, and I'm not sure why.

I should also mention that there was an attempt to create a snap package for Terminix, but without success so far.
In case you're not familiar with Tilix, this is a GTK3 tiling terminal emulator that allows splitting terminals horizontally and vertically, and rearrange them using drag and drop. The layouts can be saved and restored. For more information about Tilix (previously Terminix), see our initial article. Also check out its GitHub page.
To add the WebUpd8 Terminix / Tilix PPA and install the app in Ubuntu 16.04, 16.10, Linux Mint 18, and derivatives (32bit + 64bit), use the following commands:
sudo add-apt-repository ppa:webupd8team/terminix
sudo apt update
sudo apt install tilix
Extra tip: For additional Tilix themes, see THIS page.
