Hello Linux Geeksters. As you may know, SubDownloader is an open-source program that automatically finds and downloads subtitles for your movies. It

Main features:
- No spyware
- Recursively folders search
- Multilingual (+50 languages)
- Download entire folders of movies with just one click in few seconds
The latest version available is SubDownloade 2.0.18, which has been released a while ago.
In this article I will show you how to install SubDownloader 2.0.18 on Ubuntu 15.04 Vivid Vervet, Ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr, Ubuntu 12.04 Precise Pangolin, Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Linux Mint 13 Maya, Pinguy OS 14.04, Elementary OS 0.3 Freya, Elementary OS 0.2 Luna, Deepin 2014, Peppermint Five, LXLE 14.04, Linux Lite 2, Debian 8 Jessie, Debian 7 Wheezy and other Ubuntu and Debian derivative systems.
For Ubuntu 15.04, SubDownloader 2.0.18 is available via the default repositories so installing it is easy. Just update the local repository index and install the subdownloader package:
$ sudo apt-get update
$ sudo apt-get install subdownloader
For Ubuntu 14.10, Ubuntu 14.04, Ubuntu 12.04, Debian 8 and Debian 7, SubDownloader 2.0.18 is not available via any repository or PPA, we have to download the subdownload deb package from Launchpad and install it via command-line. I prefer gdebi over dpkg due to the fact that it is also handles dependencies.
So, to install SubDownloader 2.0.18 on Ubuntu, Debian and derivative systems, do:
$ sudo apt-get install gdebi
$ wget https://launchpad.net/subdownloader/trunk/2.0.18/+download/subdownloader_2.0.18_all.deb
$ sudo gdebi subdownloader_2.0.18_all.deb
