This howto guide shows how to install Gloobus Preview on Ubuntu 12.04/11.10, Linux Mint and Fedora 16/15/14/13/12 using PPA's and Yum repositories.

Install Gloobus Preview on Ubuntu 12.04/11.10, Linux Mint and Fedora 16/15/14/13/12

Install Gloobus Preview in Ubuntu

To install the latest Gloobus Preview in Ubuntu 12.04 or 11.10 and Linux Mint using its official PPA, use the following commands:

sudo add-apt-repository ppa:gloobus-dev/gloobus-preview
sudo apt-get update
sudo apt-get install gloobus-preview gloobus-sushi

Important Note : In the above command we also install gloobus-sushi package, which replaces GNOME Sushi (if installed). GNOME Sushi is an application similar to Gloobus Preview that was introduced with GNOME 3, which unfortunately doesn't integrate too well with Ubuntu.

Gloobus Preview also has PPA's for older versions Ubuntu and Linux Mint, but you will need to have Nautilus Elementary installed on your system. Let's install Nautilus Elementary and Gloobus Preview in older Ubuntu versions. (Please note that Ubuntu older than 11.10, don't install "gloobus-sushi"). Just follow below installation instruction.

sudo add-apt-repository ppa:gloobus-dev/gloobus-preview
sudo add-apt-repository ppa:am-monkeyd/nautilus-elementary-ppa
sudo apt-get update && sudo apt-get install gloobus-preview && sudo apt-get upgrade

If you wish to use Gloobus Preview with some documents like (odf, ods, etc.), then you'll also have to install unoconv on your Ubuntu system.

sudo apt-get install unoconv

Once installed, open Nautilus, select some file on your Ubuntu system and then press the SPACE key to quickly preview files using Gloobus Preview.

Using Gloobus Preview with Marlin

Marlin, the file manager that will be used by default in elementary OS, can also use Gloobus Preview. To set Marlin to use Gloobus Preview, install Dconf-Editor.

sudo apt-get install dconf-tools 

Next, Launch the Dconf-Editor, then navigate to apps > marlin > preferences and set "/usr/bin/gloobus-preview" for the previewer-path. Then, just like in Nautilus, use the SPACE key to quickly preview files.

Install Gloobus Preview in Fedora

Gloobus Preview is also available for Fedora based system in the updates-testing repository. But it has not been tested enough to be put into the stable release yet.

yum install --enablerepo=updates-testing gloobus-preview 
## OR ##
yum update gloobus-preview
