 * Distribution - (run ```cat /etc/os-release```)
 * Related Application and/or Package Version - apt policy $PACKAGE NAME

NAME="Pop!_OS"
VERSION="17.10 (Artful Aardvark)"
BUILD = 35 (noNVIDIA)

Issue/Bug Description
When Pop!_OS is installed without an internet connection and then a proprietary media format such as: .avi, .mov, .mp4, mp3, or .wav is played, an error returns that the required plugin could not be found. The user is not informed that with an internet connection, the proper media plugins are found and installed.

Expected Behavior

The error message seen in the screen-shot attached below should include a message that if the user connects to the internet, the plugins will be found and the file can be viewed.

@brs17 Normally the system then asks you if you want to install the plugins. What application was this in?

Bug filed against Pop!_Shop to handle codec installation. This should also fix this bug. #16

@carl I think this was being caused by a lack of internet connectivity. Totem does offer installation of the required codecs automatically when there is internet available.
