So, you want to install Picasa software for your Linux / Debian system? Easy enough, we just have to add the repository and the software key info to our package manager. Ok, fetch a snack, we’re gonna go back into the command line!

Within Debian or other Linux system, open a Terminal Window in Super User Mode (root). From the command line, we must first download the key and then install the key. Type the following at the command line:

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

Now, we add in the google repository of software for linux. Open sources.list by typing sudo nano /etc/apt/sources.list at the command prompt.

Then, add these lines at the bottom of the file:

# Google goodies
deb http://dl.google.com/linux/deb/ stable non-free

After editing this file and save it by using the CTRL-X to close sources.list.

then use apt as usual, for example, first update the packages list by typing:

apt-get update

And after updating the packages list, if you want to install Picasa, type:

apt-get install picasa
