Google releases regular updates for it’s Linux distributions of Picasa and Google Desktop applications. Picasa is an amazing image viewer and manager. It is one of my most used softwares for Linux when it comes to viewing image albums.

Default update service for Picasa is not present in Ubuntu itself, but can be easily added. Now, this can be done with a GUI as well as from the command line.

To add Google repositories from the command line, follow the steps below.

1. Add the GPG signing key for Google repositories by entering

   wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
   apt-get update

   into your terminal.

2. To add the repository URL, open the file /etc/apt/sources.list and append the following code at the end

   # Google software repository
   deb http://dl.google.com/linux/deb/
   stable non-free main

3. Update your software package update list with

   sudo apt-get update

4. Update Picasa with
   
   
   

    sudo apt-get install picasa

Now, your Picasa will update automatically with your other packages every time Google provides an update. This will also fetch package update lists for any other Google software you use.
